First indexed and scored.

## MCP tools (12)

### `lumi_check` (~219 tokens)

Lumi Check: should I pay this x402 seller? (free)

Free. Call before paying an x402 seller. Returns allow / warn / block with reasons, the seller's current Lumi score and a link to the live report card. The verdict is signed by Lumi and verified locally against the Lumi keys pinned in this package (other keys are rejected). Only the URL's origin + path is sent. For MCP tool payments pass pay_to alone. If Lumi cannot be reached within 2.5 s the answer is warn (fail-open). Paying Lumi never changes a score, tier, ranking or 'Tested by Lumi' result. The paid 'Monitored by Lumi' badge is separate and labelled as paid.

Input parameters:

- `amount_usd` (number): Price in USD, e.g. 0.01
- `network` (string): CAIP-2 network, e.g. eip155:8453 or xrpl:0
- `pay_to` (string): The payTo address from the 402 quote
- `url` (string): The x402 resource URL you are about to pay

### `lumi_scan_seller` (~135 tokens)

Lumi Check: scan an x402 seller (free, dry-run)

Free. Fetches an x402 seller's 402 quote without paying and returns latency, HTTP status and the quoted price per chain, plus a dry-run test-buy plan checked against the kit's local caps (default 0.01 per buy, 0.05 per day per asset). Nothing is signed or paid from this tool. Passive mode is the default way to contribute: report purchases you already made with lumi_report_receipt.

Input parameters:

- `body` (string): Optional JSON body for POST endpoints
- `method` (string): HTTP method (default GET)
- `url` (string, required): The x402 resource URL

### `lumi_report_receipt` (~270 tokens)

Lumi Check: report a purchase you already made (passive)

Passive contribution: builds a counterparty_delivery_receipt for an x402 purchase you already made (tx looked up on-ledger), signed by the paying wallet. With submit=true it is sent to Lumi signed with your contributor key (LUMI_CONTRIB_KEY_FILE); Lumi verifies it on-ledger before it counts. Submitting is tier 2 receipt sharing: OFF by default, so submit=true sends nothing until you opt in (LUMI_SHARE_RECEIPTS=1 or `lumi-scan sharing on`). A receipt shares the payment's chain and transaction ID (tx hash), no amount or wallet field; a transaction ID is public on-chain and can be linked to the paying wallet. Checked receipts earn a public contributor badge only (nothing of monetary value). No new spend. Self-tests (your own endpoints or wallets) are rejected.

Input parameters:

- `endpoint` (string, required): The x402 resource URL you paid
- `http_status` (integer, required): HTTP status of the paid response (0 = timeout)
- `latency_ms` (integer)
- `network` (string, required): Chain of the payment
- `outcome` (string, required)
- `submit` (boolean): Send to Lumi (default false: return the signed receipt only)
- `tx_hash` (string, required): Payment transaction hash

### `lumi_catalog` (~49 tokens)

Lumi: endpoints and prices (free)

Free. Lists Lumi API endpoints, live prices (USD; XRP / RLUSD / USDC on the XRP Ledger or USDC on Base), payment settings of this MCP server and the caller wallet address.

### `lumi_samples` (~85 tokens)

Lumi: free samples of every paid product

Free. A truncated, clearly labelled SAMPLE of each paid product (trust_check, vendor report, verdict) with its USD price and full URL, so you can judge it before paying. Lists are cut to 2 entries; up to 10 minutes old. Pass route to get one product.

Input parameters:

- `route` (string): Optional product route, e.g. trust_check or verdict

### `lumi_quote` (~106 tokens)

Lumi: price check without paying (free)

Free. Shows the x402 price quote (XRP / RLUSD / USDC on the XRP Ledger, USDC on Base) for any Lumi paid path, e.g. /v1/verdict?url=..., without paying. A 503 means Lumi cannot answer right now and the call would not be sold.

Input parameters:

- `path` (string, required): Paid API path, e.g. /v1/verdict?url=... or /v1/trust/check?url=...

### `lumi_vendor_scores` (~295 tokens)

Lumi: x402 vendor observations (free)

Free. Check an x402 seller before you pay it: pass url (the resource you are about to buy), domain, or payTo (the address in its 402 quote, case-insensitive). Lumi ingests the full CDP x402 Bazaar catalog daily and runs free, unpaid 402-quote checks of listings on a rotating schedule (valid quote, price and payTo vs the listing, latency, domain age; live coverage counts in the response), labelled 'quote-checked, low confidence', plus Lumi's own test-buys confirmed on-chain, labelled 'test-bought' and counted per chain (Base USDC buys of Bazaar listings; XRPL buys of a small curated list, separately). Answer-only: tx evidence is in the paid trust check. Observations, not ratings; no match is not a negative finding. With no arguments: the curated XRPL vendor scores and catalog counts; vendor_id gives one curated vendor's summary (tx evidence is in the paid vendor report).

Input parameters:

- `domain` (string): Seller host or domain, e.g. example.com
- `payTo` (string): payTo address from the seller's 402 quote (0x... or r...)
- `url` (string): Resource URL you are about to pay, e.g. https://example.com/api/data
- `vendor_id` (string): Optional curated vendor id, e.g. printmoneylab

### `lumi_verdict` (~251 tokens)

Lumi: one-label pre-payment check

Before paying an x402 URL or seller domain: one label from the same data and signing key as Lumi's free /v1/check: checks_passed (Delivered in recent checks), check_first (Check first), checks_failed (Recent checks failed) or no_data (Not enough data), with as-of date, evidence window, conclusive test-buy count, last delivered/failed dates, reason codes, evidence and appeal links, and observed on-chain payments as ranges only. It is the one-word version of the live check: label_live is the label after Lumi contacts the seller at call time (an unpaid request) and compares its quote, price, payTo and TLS with Lumi's record, with signed live_evidence. Costs $0.01 per call, paid with your wallet within the configured caps. Paying Lumi never changes a result. Observations, not a guarantee.

Input parameters:

- `amount` (string): Optional: the quoted price in USD, e.g. 0.01
- `payTo` (string): Optional: the payTo address in its 402 quote
- `url` (string, required): The x402 resource URL (or the seller's domain) you are about to pay

### `lumi_seller_monitoring` (~320 tokens)

Lumi: seller monitoring plans and monitored sellers (free)

Free. For x402 sellers, priced per endpoint per 30 days: Watch $5 (hourly quote checks, weekly test-buy), Watch Pro $20 (15 min checks, daily buys on up to 3 chains, limited by the test-buy budget, signed monthly report); 10+ endpoints -20% or 3 terms prepaid -10% (not stacked: the larger applies). Audit $99 one-off. Test-buy packs, one-off, valid 12 months, buys capped at $0.10 each: Re-test pack $6.50 for 30 test-buys ("Fixed something? Get re-tested now"), Founder pack $5 for 24 test-buys (first 10 sellers, one place per company, rebuy up to 12 times). Free Watch tier (1 endpoint, daily quote check, no test-buys) and a one-per-seller 14-day Watch trial (no card, never converts; on day 14 nothing is charged, checks stop, the badge comes off and history freezes read-only). Monitor, Monitor Plus and Watch Plus are no longer sold; existing terms run to their end. No auto-renew; payTo proven by signature; paying never changes a score. No args: plans, enrolment steps and safeguards. enrollment_id: that seller's public entry (disclosure, findings, replies) and live badge status. Plans are paid over x402 at the REST URL.

Input parameters:

- `enrollment_id` (string): Optional enrollment id (men_...)

### `lumi_trust_feed` (~85 tokens)

Lumi: trust data feed plans and licence (free)

Free. Licensed trust data feed for facilitators, wallets and frameworks: free key with 1,000 lookups/month (wallet signature), $1.50 per 1,000 extra lookups, Feed $99/30 days, Feed Pro $199/30 days (snapshot export, webhooks). Returns plans, endpoints and licence terms (no resale, attribution).

### `lumi_trust_check` (~284 tokens)

Lumi: trust check (paid)

Should I pay this x402 URL? allow / warn / block with coded reasons, from Lumi's daily CDP Bazaar index, free 402-quote checks and Lumi's own test-buys (Base USDC for Bazaar listings; XRPL only for a small curated vendor list, counted separately). Live: after payment Lumi contacts the seller once (an unpaid request; Lumi never pays the seller) and compares its current quote, price, payTo and TLS with Lumi's record, returned as live with signed live_evidence; the free check is cached and shows data_age. Pass url, and optionally the payTo and USD amount you were quoted, to catch address or price mismatches. Links the free lookup and, for curated vendors, the $0.02 full report. Observations, not a guarantee. Paid: $0.02 per call (USDC on Base, or XRP/RLUSD/USDC on the XRP Ledger). Pays with your own wallet via x402 (XRPL_SEED or EVM_PRIVATE_KEY) within the configured caps.

Input parameters:

- `amount` (string): Optional: the quoted price in USD, e.g. 0.01
- `payTo` (string): Optional: the payTo address in its 402 quote
- `url` (string, required): The x402 resource URL you are about to pay

### `lumi_vendor_report` (~180 tokens)

Lumi: vendor report (paid)

Detailed report on one x402 vendor from Lumi's trust list: full observation history (every free 402-quote check over 90 days, every paid test-buy with tx hash and delivered yes/no), latency stats and 7-day trend, uptime % (24h/7d/30d/90d) and daily series, quoted-price history, agent reports, vendor replies, sample sizes and confidence labels. Automated observations, not a rating. Paid: $0.02 per call (USDC on Base, or XRP/RLUSD/USDC on the XRP Ledger). The free summary is lumi_vendor_scores. Pays with your own wallet via x402 (XRPL_SEED or EVM_PRIVATE_KEY) within the configured caps.

Input parameters:

- `vendor_id` (string, required): Vendor id from lumi_vendor_scores, e.g. printmoneylab
