Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

clean

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.

mismatch

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 check.

payto

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 not a clearance.

trust

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 response.
