Lumière PayCheck

**Check any x402 endpoint before your agent pays it.** Lumière PayCheck monitors 19,000+ x402 endpoints from the Bazaar every 30 minutes and makes real test payments to confirm they deliver what they charge for. Your agent gets a clear answer before any money moves. ### What your agent can do - **Check an endpoint:** trust score (0–100), grade (A–F), and a verdict: *proceed*, *caution*, or *avoid* - **Authorize a payment:** confirm the price isn't inflated and the payout wallet hasn't been swapped (hijack detection) before paying - **Find safe endpoints:** the most trustworthy x402 services right now, ranked - **Report outcomes:** flag a paid call that didn't deliver, which triggers an independent re-test ### Why trust it - Real paid delivery tests, not just uptime pings - Payout-wallet changes checked against seller declarations and on-chain evidence - Published scoring formula; grades are never paid for ### Free to use No API key or signup. Add the server and ask your agent to check before it pays. ### For teams Running several agents? Plans give each agent its own key with spend limits, human review for unusual payments, signed receipts, and a full audit trail. **Builder** $9/mo · **Business** $49/mo · **Enterprise** custom → [lumierepaycheck.org/subscribe](https://lumierepaycheck.org/subscribe) [Website](https://lumierepaycheck.org) · [Docs](https://github.com/Book0fEli/lumiere-paycheck)
