# Lumi Trades

> Should I pay this x402 URL? Lumi Trades is an x402 seller trust service: start with the free trust check (trust_check, GET /v1/trust/check), allow / warn / block with coded reasons from daily CDP Bazaar index checks and Lumi's own on-chain test-buys. Paid: high-value check, vendor reports and receipt lookups; signed delivery receipts come with paid receipt lookups (/v1/trust/receipts), vendor reports and Feed catalog lookups, verifiable free. Paid checks settle per call over x402 v2 with no API key or account, in XRP or RLUSD or USDC on the XRP Ledger, or USDC on Base, or USDC on Stellar. Also available as a remote MCP server.

## Skills

- **Catalog: endpoints, prices, payment networks (free)**: Lists every Lumi endpoint with live prices on every payment network (XRP Ledger, Base, Stellar), the MCP and A2A endpoints, and the not-charged-when-Lumi-cannot-answer guarantee.
- **High-value check before a larger x402 payment: same verdict + live re-check + signed receipt (paid, 0.5% of the amount)**: Use this before your agent makes a larger x402 payment. The basic GET /v1/trust/check is free (100 checks a day per IP and per key); this paid version gives the same allow / warn / block verdict with coded reasons and the same score (paying never changes them), plus: 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 (signed as live_evidence), and a Lumi-signed receipt bound to the stated amount (lumi_receipt, paid: true). Query: url (required), amount (required: the USD amount you are about to pay), payTo (optional, to catch an address mismatch). Price: 0.5% of the stated payment amount (amount, USD), minimum $0.005, maximum $0.25; e.g. amount=10 costs $0.05. Observations, not a guarantee. Not charged on bad input. Paid per call via x402 at https://api.lumitrades.io/v1/trust/check/high-value: 0.0042 XRP / 0.005 RLUSD / 0.005 USDC on the XRP Ledger, or 0.005 USDC on Base, or 0.005 USDC on Stellar. Over A2A this skill returns the live payment terms; it is never charged when Lumi cannot answer.
- **Price quote for a paid call, without paying (free)**: Live x402 v2 quote (all accepts options) for a paid skill or path, e.g. {"skill":"high_value_check","url":"...","amount":"25"} or "quote /v1/verdict?url=...". A 503 means Lumi cannot answer right now and would not sell the call.
- **Free samples of every paid product**: Free, clearly labelled SAMPLE previews of every paid product (truncated, up to 10 minutes old), with the USD price of each. Use it to see the output shape before paying.
- **Seller monitoring plans for x402 sellers (info free; plans paid at the REST URL)**: For x402 sellers, priced per endpoint per 30 days: Watch $5 (hourly quote checks, weekly test-buy, alerts), 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%, 3 terms prepaid -10% (discounts do not stack: the larger applies). Audit $99 one-off (every listed endpoint, signed report). Test-buy packs, one-off: 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); both valid 12 months, each buy capped at $0.10. 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). Seller-funded, no auto-renew, payTo proven by signature; paying never changes a score. Answers with the plan table and enrolment steps; payment happens at GET /v1/monitor/subscribe/{plan}?enrollment=<id>&endpoints=<N>.
- **Should I pay this x402 URL? allow / warn / block (free, rate-limited)**: Should I pay this x402 URL? {"url":"...","payTo":"...","amount":"0.01"} answers allow / warn / block with coded reasons and a Lumi-signed receipt, free: 100 checks a day per IP and per key (GET /v1/trust/check). For a larger payment, the paid high_value_check skill adds a live re-check of the seller (0.5% of the stated payment amount (amount, USD), minimum $0.005, maximum $0.25; e.g. amount=10 costs $0.05.)
- **Trust data feed for facilitators, wallets and frameworks (info free; keys and plans at the REST URL)**: Licensed trust data feed: 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). Answers with plans, endpoints and licence terms; keys and payments at the REST URLs under /v1/feed.
- **x402 vendor report: full observation history for one vendor (paid)**: Use this when you need evidence before paying an x402 vendor on Lumi's trust list: the full observation history. Every free 402-quote check (90-day retention) with status, quoted price and latency; every paid test-buy with amount, ledger tx hash, explorer link and delivered yes/no; latency stats (min/p50/p90/p95/max) and the 7-day trend; uptime % over 24h/7d/30d/90d and a daily series; per-endpoint quoted-price history; agent reports; vendor replies; score components, sample sizes and confidence labels. Automated observations, not a rating. Not sold (503, not charged) when the vendor has no observation in the last 48 h. The free summary is GET /v1/trust/vendors/<vendor id>, e.g. /v1/trust/vendors/printmoneylab. Paid per call via x402 at https://api.lumitrades.io/v1/trust/vendors/{id}/report: 0.0166 XRP / 0.02 RLUSD / 0.02 USDC on the XRP Ledger, or 0.02 USDC on Base, or 0.02 USDC on Stellar. Over A2A this skill returns the live payment terms; it is never charged when Lumi cannot answer.
- **x402 seller lookup and observations (free)**: Check an x402 seller before paying it: {"url":"..."}, {"domain":"..."} or {"payTo":"..."} (case-insensitive) looks it up in the full CDP x402 Bazaar catalog (free quote checks of listings on a rotating schedule: 'quote-checked, low confidence'; live coverage counts in the response) and Lumi's on-chain-confirmed test-buys ('test-bought', counted per chain: Base USDC for Bazaar listings, XRPL for a small curated list). Answer-only; for an allow / warn / block verdict use the free trust_check skill. With no arguments: curated XRPL vendor observations; {"vendor_id":"..."} for one vendor's summary. Observations, not ratings; no match is not a negative finding.
