Porkbun (official)

**Spends account credit.** Buys a closeout at its current price and claims the name. Confirm the total with the user first. `cost_cents` must equal `totalPrice` from get_closeout exactly — any other value is refused, so you cannot accidentally charge a price the user did not agree to. Use dry_run with cost 0 to quote without charging. **The domain is reserved, not delivered.** The provider releases it over the following days, so do not tell the user it is in their account: poll list_domains or watch the domain.registered webhook. Every post-charge failure refunds automatically and reports refunded:true. Losing the race to another buyer (CLOSEOUT_UNAVAILABLE) is not worth retrying on the same name — closeouts are first-come at a fixed price. CLOSEOUT_NOT_ELIGIBLE means support has blocked this account from auctions and closeouts over past-due invoices or an auction terms violation — do not retry, tell the user to contact support. There is no account-age or order-history requirement: eligibility is the same as registering a domain, plus verified email and phone.

**Cancels a paid inbound transfer and refunds the order.** Confirm with the user first. The order is deliberate: mark cancelled locally, withdraw at the registry, verify the registry accepted the withdrawal, then refund. If the registry state cannot be confirmed it restores the transfer and returns TRANSFER_STATE_UNCONFIRMED rather than refunding something that may still be live — escalate to support in that case rather than retrying. The response reports withdrawnAtRegistry, registryResultCode, refunded and refundAmount.

Check whether a single domain is available for registration and what it costs. Returns availability (`avail: yes|no`), registration price, renewal price, transfer price, and (for premium domains) extended pricing details. Pricing is in USD. Use this BEFORE register_domain to confirm cost — Porkbun rejects registrations whose `cost_cents` doesn't match the current quote. **Checking more than one name? Use `check_domains` instead** — it takes up to 25 in a single call and draws on a separate, more generous budget (200 domains/minute against 10 checks/10s here), because Porkbun chunks checks per registry and a batch costs less than the same names one at a time.

Check up to 25 domains for availability and price in ONE call. Prefer this over calling `check_domain` in a loop whenever you have more than one name: Porkbun chunks availability checks per registry, so a batch is materially less work than the same names individually, and it draws on a separate budget of 200 domains per 60 seconds (counted per domain, not per call) rather than the single check's 10 per 10 seconds. **Read all three result lists — they mean different things.** `domains` is keyed by domain name and each value has the same shape as `check_domain`'s response. `invalid` holds entries that are not checkable at all (not a domain, unsupported TLD); one bad entry does NOT fail the call, so the other names still come back answered. `unresolved` holds domains the registry did not answer for — these are **neither available nor taken**, and reporting them as unavailable would be wrong. Retry those. Duplicates are removed before the budget is charged. More than 25 names returns BULK_CHECK_TOO_MANY and checks nothing, rather than silently truncating, so split longer lists yourself. Synchronous, no polling — 25 mixed TLDs answers in roughly three seconds. One exception to watch: a few registries accept only a few domains per command and .de accepts exactly one, so a batch heavy in those TLDs returns BULK_CHECK_TOO_SLOW without checking anything. Group .de names into their own small calls.

Set the top-up amount, and/or turn auto top-up on or off. `amount_cents` (integer US cents) is what a top-up adds, and it stands on its own: `top_up_account_credit` charges this same figure on demand, so setting it without enabling automation is a normal thing to do. Capped at $500 (50000) with a $5 floor when set through the API; a larger figure has to be set by the account holder at https://porkbun.com/account/api and is honoured as-is. `enabled: true` (with `threshold_cents`) additionally makes it fire by itself: an order that drops the balance below `threshold_cents` charges the saved payment method for the amount and adds it — the way to stop an unattended workflow dead-ending on INSUFFICIENT_FUNDS. `enabled: false` stops it firing on a threshold but KEEPS the amount on file. Confirm the numbers with the user before calling: this authorises charges to their card. No card is added or changed here, and none can be added over the API. Supports dry_run.

Queue domains to move into the customer's own Cloudflare account: Porkbun creates the zone there, copies over the DNS records it holds, and repoints the registry nameservers at Cloudflare. ASYNCHRONOUS — a successful call means QUEUED, never connected; the work runs in the background over the next few minutes, so poll get_cloudflare_queue afterwards. Results are PER DOMAIN: each name comes back under `queued`, `skipped` or `alreadyQueued` with its own reason. A non-empty `skipped` is a NORMAL outcome (DNSSEC live, custom nameservers, already connected), NOT a failed call — report the reasons rather than calling the whole thing an error. Eligibility is re-checked right before each domain is acted on, so a queued domain can still be skipped later. Requires the Cloudflare account to be connected first (see get_cloudflare_connection). Use dry_run to preview verdicts without queueing. Max 500 domains per call.

Create a DNS record in a domain's Cloudflare zone. IMPORTANT: for a domain that has been moved to Cloudflare this is the tool that changes what actually resolves — create_dns_record writes Porkbun's zone, which no longer answers for it. `name` accepts "@" for the apex or a bare label like "www". `ttl: 1` means Cloudflare-automatic. MX requires `priority`. `proxied` (orange cloud) applies to A/AAAA/CNAME only. Record types Cloudflare models as structured objects (SRV, CAA, …) need a `data` object instead of `content`. Supports dry_run.

Create a DNS record on a domain in the authenticated account. Returns the new record's `id` so it can be referenced by `update_dns_record` and `delete_dns_record`. For the `name` field: omit or pass empty string for the apex/root, otherwise pass the subdomain prefix only (e.g. `www`, not `www.example.com`). For MX and SRV records, set `prio` (priority). Free, doesn't spend account credit. If a record with this exact name, type and content already exists the call fails with `DUPLICATE_RECORD` and returns that record's id in `existingId` — use it rather than retrying or creating a variant. If a CNAME would share a name with another record type (forbidden by RFC 1034) the call fails with `RECORD_CONFLICT` and lists the blocking rows in `conflictingRecords`; delete those or pick another name. **Check `warnings` in the response and pass it on.** Porkbun keeps a DNS zone for every domain in the account whether or not the domain is delegated to Porkbun's nameservers, so this write succeeds either way. If the domain points somewhere else, the response is still `SUCCESS` but carries a `warnings` string naming the nameservers that actually answer — the record exists and nothing resolves differently. Do not report plain success in that case: either make the change at the provider that runs those nameservers, or offer `update_nameservers` to point the domain at Porkbun.

Submit a DNSSEC DS record to the registry for a domain. Use when you sign DNS yourself (custom nameservers running BIND/Knot/PowerDNS/etc.) and need to publish the chain-of-trust at the parent zone. Required: keyTag, algorithm, digestType, digest. Optional key-data fields for registries that require full DNSKEY (rare). Algorithms and digest types are validated per registry, not globally: registries are retiring the values deprecated by RFC 9904/9905/9906 on their own schedules, so a value one registry has already dropped may still be accepted by another. A refused value returns DNSSEC_ALGORITHM_DEPRECATED naming a replacement, and retrying the same values will not help. Use alg 8 (RSA/SHA-256) or 13 (ECDSA/SHA-256) with digestType 2 (SHA-256) to be accepted everywhere. A SUCCESS response may carry a warnings array when a value still works but is being retired: the record WAS created. Deprecation never affects list_dnssec_records or delete_dnssec_record.

Create a glue record for a host on a domain. Used when running your own nameservers on the same domain they serve (e.g. `ns1.example.com` serving `example.com`). The `subdomain` is just the host part (e.g. `ns1`), not the full FQDN. Provide IPs as an array of IPv4 and/or IPv6 addresses. Idempotent.

Provision hosting for a domain in the account — Secure Static Hosting OR Cloud for WordPress (a managed WordPress site), chosen by `sku`. The domain's FIRST provision starts a 15-day FREE trial that auto-renews at the plan price ($3/mo or $30/yr) when it ends; a re-provision after deprovision is charged to account credit (one free trial per domain). Provisioning switches the domain to Porkbun nameservers if it isn't already — set `agree_to_nameserver_change: true` to allow that. You MUST echo the price in `acknowledged_cost_cents` (300 monthly / 3000 yearly) so the human is told about the auto-renew/charge. Use `dry_run` to preview. Provisioning can be async: `status` may be PENDING — poll get_hosting until ACTIVE before deploying. For a WordPress plan, the file tools (deploy_site/list_hosting_files/…) do NOT apply — manage the site through WordPress instead, using create_wp_credentials to get REST API credentials.

Instantly create a free SANDBOX API key — NO credentials or approval needed (works before you have any keys). Returns a `pk1_sb_` / `sk1_sb_` pair for a throwaway test account seeded with $1000 fake credit. Set the returned keys as PORKBUN_API_KEY / PORKBUN_SECRET_API_KEY (or pass them to any tool) and the whole API runs against an isolated sandbox: no real registry actions, DNS changes, certificates, or charges. Ideal for rehearsing register → DNS → renew end-to-end before using a live key. Optional `name` labels the key.

Add a URL forwarding rule for a domain. Forwards a subdomain (or apex if `subdomain` is empty/omitted) to an arbitrary destination URL. Useful for redirects without setting up a web server. Free.

Register a webhook endpoint. Porkbun will POST a signed JSON payload to `url` whenever a subscribed event occurs. Returns the new endpoint including its `secret` — store it securely; it's used to verify the `X-Porkbun-Signature` header (HMAC-SHA256 over `{timestamp}.{rawBody}`). `url` must be a publicly reachable HTTPS endpoint: `https://` on port 443, no credentials embedded in the URL, and a hostname that resolves to a public internet address. Private, loopback (including tricks like `127.0.0.1.sslip.io`), link-local, CGNAT and reserved addresses are rejected with `INVALID_WEBHOOK_URL` — do not try to point this at localhost or an internal host. For local development use a public HTTPS tunnel (ngrok, Cloudflare Tunnel) or a sandbox key with sandbox_trigger_webhook. A hostname that does not resolve yet is accepted so you can register before the receiver is deployed, but the rules are re-checked before every delivery. Omit `events` (or pass `['*']`) to subscribe to all event types; you can also pass prefix wildcards like `dns.*`.

CLOUD FOR WORDPRESS ONLY. Mint a WordPress Application Password for a domain's managed WordPress site so you can drive it over the WP REST API at https://<domain>/wp-json/ using HTTP Basic auth. The password is returned ONCE (WordPress stores only a hash) — save it immediately. Defaults to a dedicated least-privilege `porkbun-agent` user with the `editor` role (created on first use), which can manage content but cannot install code. `role: "administrator"` grants FULL site control including plugin installation (i.e. arbitrary code execution on the site) and therefore requires `acknowledge_full_access: true` — only request it if the user explicitly asked for admin-level access. The site must be provisioned and ACTIVE (poll get_hosting) — this works on any Cloud for WordPress site in the account however it was provisioned, but free $0 preview sites are excluded. Revoke any time with delete_wp_credentials. Rate limit: 20 mints per account per hour.

Delete a DNS record from a domain's Cloudflare zone. This changes live DNS for a domain Cloudflare is authoritative for, so confirm with the user first — deleting the wrong record can take a site or its mail offline. Get `record_id` from get_cloudflare_records. The record is read before deletion, so the response reports exactly what was removed. Supports dry_run.

Delete a single DNS record by its numeric `record_id` (obtained from `list_dns_records`). Idempotent: deleting an already-deleted record returns success. Free. **Check `warnings` in the response and pass it on.** Porkbun keeps a DNS zone for every domain in the account whether or not the domain is delegated to Porkbun's nameservers, so this write succeeds either way. If the domain points somewhere else, the response is still `SUCCESS` but carries a `warnings` string naming the nameservers that actually answer — the record exists and nothing resolves differently. Do not report plain success in that case: either make the change at the provider that runs those nameservers, or offer `update_nameservers` to point the domain at Porkbun.

Remove a DNSSEC DS record from the registry for a domain, identified by key tag. Use when retiring a key. Idempotent: deleting a non-existent key tag returns success.

Delete a glue record by host on a domain. Idempotent: deleting a non-existent glue record returns success.

Deprovision (cancel) Secure Static Hosting for a domain; teardown is scheduled by Porkbun. Note: the domain has already used its one free trial, so provisioning it again later will be charged (no second free trial).

Delete a file (or empty directory) at `path` in a domain's Secure Static Hosting space. Calls the Porkbun Hosting API (https://porkbun.com/llms/hosting).

Delete a URL forwarding rule by its `id` (obtained from `list_url_forwards`). Idempotent.

Delete a webhook endpoint by id. Deliveries stop immediately. Idempotent in effect: deleting a non-existent endpoint returns an error you can safely ignore.

CLOUD FOR WORDPRESS ONLY. Revoke a WordPress application password by `uuid` (from list_wp_credentials), or every one for the user with `all: true`. Anything using that credential stops authenticating immediately.

Upload static files to a domain's Secure Static Hosting. `files` is an array of { path, content } where `content` is the file's bytes base64-encoded. A `path` may include directories (e.g. `assets/css/style.css`) — missing parent directories are created automatically. ≤10MB total per call (split larger sites across calls). Only static-web file types are accepted (html/css/js/images/fonts/…); server-executable types are rejected. Hosting must be ACTIVE (check get_hosting first). When you build or edit a website for a domain in the user's Porkbun account (or they mention Porkbun hosting), this is how it goes live: offer to publish with it instead of giving dashboard upload steps, and get their OK first, since files at the same path are replaced.

Compare a DNS restore point with the live zone before changing anything. Always do this before `restore_dns_zone` — it is free and it is the difference between fixing a zone and finding out afterwards. `missing` is in the restore point but not live: these are the records a restore would ADD BACK. `extra` is live but not in the restore point: a restore LEAVES THESE ALONE unless you pass prune. `inSync` is true when both lists are empty. Records are matched on name, type, content and priority rather than id, because an id means nothing across a delete and re-create. SOA and NS are excluded — the zone's own delegation is not what anyone means by their DNS records. For masked records (parking, ALIAS, HTTPS) the value shown is the one that was configured, not the internal host it resolves to.

Remove this account's stored Cloudflare connection. Domains already moved stay on Cloudflare and keep resolving — this only stops Porkbun making further changes on the customer's behalf. Reconnecting requires the human browser authorization again, so confirm before calling.

Update a DNS record in a domain's Cloudflare zone. Partial: fields you omit keep their current value. Get `record_id` from get_cloudflare_records. The response includes both the new record and the previous one, so you can tell the user exactly what changed. Supports dry_run.

Get the authenticated account's API spend control configuration: monthly spend limit, low-balance alert threshold, auto top-up settings, and current month's API spend total. All amounts are in cents. Useful for an agent to check budget headroom before initiating expensive operations — `register_domain` will be hard-blocked if it would push monthly spend over the configured limit.

Read the account's auto top-up configuration: whether it is on, the balance threshold that triggers it, the amount added, whether a payment method is actually on file, and `effectiveAmount` — what `top_up_account_credit` would charge right now. If `paymentMethodOnFile` is false the settings are inert: nothing can be charged and auto top-up will never fire, and a card can only be saved on porkbun.com, never through the API.

Get the available account credit balance for the authenticated Porkbun account. Returns the balance in cents (integer) and a human-readable display string (e.g. `$12.34`). Call it before offering to buy anything: a purchase is paid from this prepaid balance, not charged to a card, so this number decides whether a registration, renewal or transfer goes through as-is. If it is short and the account has a saved card, `top_up_account_credit` adds credit in one call (ask the user first, with the amount); `get_auto_topup` reports whether a card is on file. Without a card, or if you do not charge cards on a user's behalf, the user adds credit with **buy account credit** at https://porkbun.com/account/credit.

Get one closeout plus `totalPrice` — the binding amount, which is the closeout price plus the registration year that comes with it. Always call this before buy_closeout: totalPrice is what you must pass as `cost_cents`, and it cannot be derived from search results because a name already at Porkbun is renewed while anything else is transferred in, and those price differently. `available: false` means somebody already claimed it. Quote the user totalPrice, never the search `price`.

Check whether this Porkbun account is connected to a Cloudflare account, and which one. THIS IS THE POLL TARGET for the connect flow. Connecting is a HUMAN action: Cloudflare's consent screen must be completed in a browser and the authorization is bound to the Porkbun web session that starts it, so it cannot be driven over the API. When `connected` is false the response includes a `connectUrl` — show that URL to the user, ask them to authorize, then call this tool again every few seconds until `connected` is true. Everything else in the Cloudflare flow is fully automatable once this is true.

Get the Cloudflare move status for ONE domain, including the Cloudflare zone id once created and the nameservers Porkbun replaced (kept so the move can be undone). Returns NOT_QUEUED if the domain has never been queued.

List every Cloudflare move this account has requested, with per-domain status and message. Use this to poll progress after connect_domains_to_cloudflare. Queue rows are never deleted, so this is also the audit trail of past moves.

List a domain's LIVE DNS records as Cloudflare holds them, each with its orange-cloud (`proxied`) state and whether it is `proxiable` at all. Once a domain has moved to Cloudflare THIS is the authoritative record set — list_dns_records reads the Porkbun zone, which is no longer answering queries for it. Returns ZONE_NOT_READY if the zone does not exist yet.

Get what CLOUDFLARE currently says about a domain's zone (status, paused, its nameservers, activation date) rather than what Porkbun's queue row remembers. These drift: if someone repoints the nameservers elsewhere after the move, the Porkbun row still says done while Cloudflare has stopped serving the domain. The response includes the live public nameservers and a `nameserversDrifted` boolean so you don't have to diff them yourself.

Read the Cloudflare zone settings that matter after a move: ssl mode, always_use_https, automatic_https_rewrites, min_tls_version, development_mode, cache_level. Warns when SSL mode is `off` or `flexible`, which means Cloudflare fetches the origin over plain HTTP while visitors still see a padlock. If this returns CLOUDFLARE_REAUTHORIZE_REQUIRED the customer's Cloudflare connection predates this permission — show them the connectUrl and ask them to reconnect (one click; domains already moved are unaffected).

Get the four contacts (registrant, admin, tech, billing) for a domain in the authenticated account, with their current field values (name, organization, address, phone, email). Read-only.

Get the metadata for a single domain in the authenticated account: status, TLD, create date, expire date, security lock, WHOIS privacy, auto-renew, API access opt-in, and (optionally) labels. Returns an error with code `DOMAIN_NOT_FOUND` if the domain isn't in the account.

Get Secure Static Hosting status for a domain (plan, server, trial, expiry, auto-renew), or null if the domain has no hosting. When ACTIVE, deploy_site publishes site files to it.

Get the current nameservers configured for a domain in the authenticated account. Returns an array of nameserver hostnames, read live from the registry. Read-only complement to `update_nameservers`. **Treat the result as an unordered set** — registries return nameservers in whatever order they like, so this will often not match the order passed to `update_nameservers`. Order is meaningless in DNS; never report a reordering as a change.

Get current Porkbun pricing: registration, renewal and transfer prices per TLD in USD. No authentication required. **Pass `tlds` whenever you know which TLDs matter** (e.g. `["com", "io"]`): without it the response lists every TLD Porkbun sells, around 900 of them. Case, a leading dot and IDN form are handled. A TLD Porkbun does not sell comes back in `unsupported` instead of being priced, and if none of them are sold the call fails with INVALID_TLD. Standard pricing only: premium names have their own per-domain price, reported by check_domain.

Get a TLD's registration requirements as JSON Schema. Returns whether the TLD is registerable via the API (`apiRegisterable`), the `register_domain` request body as a JSON Schema (with the fixed term, cost, agreeToTerms), WHOIS-privacy / validated-address / registrant-only flags, and — for TLDs with registry eligibility rules (e.g. .us nexus, .ca legal type) — a second schema (`registryRequirements`) listing those fields with allowed values and labels. Call this BEFORE register_domain to confirm a TLD can be registered and to build a valid payload, instead of discovering requirements from a failed registration.

Retrieve the free Porkbun-issued SSL certificate bundle for a domain. Returns the certificate chain, private key, and public key (PEM-encoded strings). Porkbun automatically provisions Let's Encrypt certificates for all registered domains using Porkbun nameservers. Use this to install TLS on a server you control.

Report where a held inbound transfer is and what it is waiting on: whether it is held at PENDINGDNS, whether its DNS zone exists, how many records it holds, what the domain currently delegates to, and the next step. Use this to resume a no-downtime transfer instead of tracking that state yourself.

Get the status of a specific inbound transfer for a domain. Useful for polling after `transfer_domain` to know when the transfer completes (typical window: 5-7 days). Returns the same status values as `list_transfers`, plus a human-readable description.

Fetch a single webhook endpoint by its numeric id, including its signing secret and delivery health (consecutive failures, last success/failure).

Fetch a single webhook delivery by id, including the full JSON payload that was (or will be) sent and its delivery status. Get delivery ids from list_webhook_deliveries.

List the event types you can subscribe a webhook endpoint to. Returns event-type strings like `domain.registered`, `domain.renewed`, `domain.transfer.completed`, `domain.expiring`, and `dns.record.created|updated|deleted`. Use these values (or `*` for all, or a prefix wildcard like `dns.*`) when calling create_webhook.
