  "instructions": "Trust tooling for agents, free — check before you pay. merona is an independent x402 settlement index (it does not run payment rails and holds no seller relationships), so an agent can verify a seller wallet before it sends funds.\nAll four tools are free — no API key, payment, or signup required: payto_check checks one wallet or endpoint's payout integrity before you pay it; mismatch_feed lists the current payout mismatches (top 10; full feed at merona.io/mismatches.json); clean_stats reports wash-adjusted settlement volume per chain; trust_score returns a wash-aware seller grade with a re-derivable snapshot hash (optionally pay $0.001 via x402 for a settlement-receipted response).\nCall them freely — no auth handshake needed.",
