Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons.

Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 api_sat per call. Proof is verified by ``debit_or_deny`` before any cost is incurred.

Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned).

Get a non-spoiler Socratic hint for an open journal entry. history is an optional JSON-encoded array of prior {question, answer} turns from this clue conversation, so follow-on questions have context. The wheel caps it hard, so oversupplying gains nothing. Returns a **claim check**, not the hint. Redeem the ``claim_check`` with ``optionality_fetch_tip``, polling until ``status`` is ``done``. A degenerate question (empty or oversized) needs no LLM, so it returns a settled ``{status: "done"}`` nudge directly instead of a claim to poll.

Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Authority. This is the operator's own funding — not a patron balance. Free.

Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), use authority_check_balance instead. Free — no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances.

Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free — no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID.

Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free — no credits required.

Check whether a previously-cached dpop_token is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Free, no side effects — does not evict the cache or touch relays.

Generate a fresh options trading scenario and open a journal entry.

Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operator — requires proof.

Hard-delete a journal entry and recompute the leaderboard cache.

Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

Deposit a freshly-generated nsec for operator-managed Nostr signing. Trade-off: sovereignty for UX. Optionality holds the nsec encrypted in Neon (AES-256-GCM, key derived from operator nsec). Until you withdraw it, the operator can sign Nostr DMs on your behalf. Use this only for fresh game-persona keypairs — never for an existing Nostr identity that lives elsewhere. The nsec MUST derive to the same npub that authenticated this call, or the deposit is rejected.

Redeem a judge_trade claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the judge_trade response (``entry_id`` + ``evaluation``). ``expired`` means the claim is unknown or its result aged out — submit the trade again.

Redeem a deal_scenario claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the deal_scenario response (``entry_id`` + ``scenario``). ``expired`` means the claim is unknown or its result aged out — start a new deal_scenario request.

Redeem an ask_tip claim check. Free. While ``status`` is ``running``, wait ``poll_after_seconds`` and call again. When ``done``, ``result`` holds the ask_tip response (``tip``). ``expired`` means the claim is unknown or its result aged out — ask again.

Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``.

Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a write.

Aggregated LLM usage and cost for this patron's calls. Returns ``{"models": [{"model", "runs", "total_calls", "total_input_tokens", "total_output_tokens", "total_cost_usd", "priced_runs"}, ...], "totals": {...}}``. One row per distinct model the patron's tool calls have invoked. ``total_cost_usd`` is what the PROVIDER reported for those calls, not a figure reconstructed from a price table — tokens from two models are not comparable money, so a local table goes wrong the moment the route changes model. ``priced_runs`` says how many of ``runs`` carried a reported cost, so a caller can render "$0.42 across 3 of 5 runs" rather than implying the rest were free. ``totals.avg_cost_usd`` is what one call actually costs to serve — the number that says whether a tool's sats price covers its own compute.

Return ``{"escrowed": bool}`` — whether Optionality holds the patron's nsec. Free; the FE polls this to render Withdraw vs Deposit affordances on the Profile page.

Return the full journal entry including scenario + evaluation.

Global leaderboard ordered by ``sort_by``.

The caller's leaderboard row plus their ordinal rank under ``sort_by``.

Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile if none is published.

Generate a Merkle inclusion proof that a patron's balance was included in a Bitcoin-notarized snapshot.

Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free.

List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are never exposed — use this to verify which fields are configured and how old each one is. Free. Proof of npub ownership is required: the list of configured fields is itself sensitive (reveals which integrations a patron has set up).

Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup.

Return the caller's profile — display_name, avatar, bio, relays.

Get the active pricing model for this operator. Free. If no model exists, self-initializes a scaffold with all registered tools at 0 sats. No economic data from code.

List a target patron's shared evaluated entries — newest first. Public, free read: anyone (including guests) can browse the trades a leaderboard peer has chosen to share. Eager-loads the evaluation and trade proposal so the FE can render the full assessment with no follow-up call. No npub/proof envelope — this is a bootstrap-style tool the FE invokes without identity injection.

Evaluate the trainee's trade. Persists evaluation, parses legs, recomputes leaderboard. Returns a **claim check**, not the evaluation. Redeem the ``claim_check`` with ``optionality_fetch_judgement``, polling until ``status`` is ``done``.

Return canonical (tool_id, mcp_name, …) for every registered tool. The authoritative source for any client (Studio, agents, FE) that needs to know how this MCP identifies its tools. Reconcile uses this output to UUID-join against the stored pricing model — no name-based UUID derivation, no guessing. If the operator renames a function or rebrands a slug, the mcp_name in this output changes but tool_id stays. That's the whole point of the canonical-UUID design. Free, no side effects.

List all available constraint types and their parameter schemas. Returns the type, category, description, and parameter specs for every constraint that can be used in a pricing pipeline. Free — no credits required.

List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter — the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator — requires proof.

Server-side sorted, grouped, paginated list of the caller's journal. Sorting and grouping are done in SQL, so each page is a slice of the fully-ordered dataset. Returns ``{total, page, page_size, groups, entries}``; ``groups`` carries per-group counts over the whole set.

List the coupons this patron has redeemed on this operator. Returns both active and exhausted redemptions with a per-row ``status`` (``active`` / ``window_closed`` / ``patron_limit`` / ``total_limit``). Free — requires proof of ``npub``.

List recent Bitcoin notarization records.

Create a new operator-owned discount coupon.

Build a Merkle tree of all patron balances and submit the root to Bitcoin via OpenTimestamps. Operator-only background task. Bitcoin confirmation takes 1-6 hours. Free — no credits required.

Describe the DPYC ecosystem via the Oracle. Free.

Get the current DPYC certification tax rate. Free.

Get DPYC onboarding instructions from the Oracle. Free.

Look up a DPYC community member by npub. Free.

Get active network advisories from the Oracle. Free.

Publish a CLIENT-SIGNED kind-0 profile to relays for an npub. The wheel never holds a patron nsec. The frontend signs the kind-0 metadata event with the patron's session key or a NIP-07 extension and passes the signed event (JSON) here; the wheel verifies the signature matches the npub, then relays it to public relays. The signature is the authorization — no proof token, no key custody. Free.

Buy credits via Bitcoin Lightning. Creates a Lightning invoice. Pay it with any Lightning wallet, then call check_payment to confirm. Proof of npub ownership is required so credits land in the correct ledger. Free — no credits required to call.

Pick up credentials from the Secure Courier. Completes the CREDENTIAL-DELIVERY flow (the ownership-proof counterpart is ``receive_npub_proof``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response you want with ``(sender_npub, service, dpop_token)`` and the tool drains ONLY the rendezvous relay that channel was pinned to. Every popped DM with the wrong session phrase is deleted and its sender is NACK'd; the first DM with the matching phrase is accepted (ACK'd) and the scan stops. If none match, the queue is drained and a ``courier_not_found`` result is returned. Do NOT poll, loop, or retry. If a credential_card (ncred1...) is provided, it is redeemed directly without any relay access (dpop_token not required for that path). On success, the payment processor client is reinitialized from the new credentials — no server restart needed.

Receive npub ownership confirmation from a patron. Completes the npub-OWNERSHIP-PROOF flow (the credential-delivery counterpart is ``receive_credentials``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response with ``(patron_npub, dpop_token)`` — the ``dpop_token`` being the value returned by ``request_npub_proof``. The tool drains ONLY the pinned rendezvous relay that challenge was published on, stopping at the DM whose phrase matches. Mismatched DMs are deleted and NACK'd (without revealing the expected phrase). If called before the user replies, their message will never be found. Do NOT poll, loop, or retry. The signed DM itself proves npub ownership (the patron's nsec signed it). On success, returns the ``dpop_token`` — the same token. The calling application MUST remember it and pass it as the ``dpop_token`` parameter on every subsequent paid tool call. The proof (a hash of the token) is stored in the vault keyed by that hash — the MCP never stores the raw token itself. Free.
