Tools: payto_check mismatch_feed clean_stats trust_score
payto_check | Check whether an x402 endpoint or wallet pays out where it claims to, before your agent sends funds. Takes one wallet address or endpoint URL. Returns any catalog-vs-live payout mismatch, dated payout-rotation history, and whether the address has settled on chain. Free, no key. Use mismatch_feed instead to list every known mismatch. Records are dated facts, not accusations, and no record found is params: query* |
mismatch_feed | List x402 endpoints currently advertising one payout address while asking payers for another, from merona's nightly probe of the public catalog — the top 10 entries with advertised vs live addresses, full counts and as-of dates (complete feed, uncapped: merona.io/mismatches.json). Takes no arguments. Free, no key. Use payto_check instead when you already have a specific address or endpoint to chec params: none |
clean_stats | Get wash-adjusted x402 settlement volume per chain — spend that survives removal of funded loops and self-dealing cycles, which can differ from raw transfer totals by orders of magnitude. Returns clean settlement count, clean volume in USD and an as-of date per chain. Takes no arguments. Free, no key. These are the figures published on merona.io. params: none |
trust_score | Score a specific seller wallet before paying it: wash-aware m.Score with an A–F grade, component breakdown, wash flags including multi-hop cycle detection, and the snapshot SHA so the result can be re-derived independently. Requires chain and address. Free — no key or payment needed. Optional: pass payment=<base64 X-PAYMENT payload> to pay $0.001 via x402 and receive a settlement-receipted respons params: chain*, address*, api_key, payment |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
