Tools (12)

convert_to_csvConvert a table to CSV without changing any value; verified by round-trip. Costs $0.05 USDC (x402).
deduplicateRemove duplicate rows by exact key, keeping the first or last, and report conflicting columns per group. Costs $0.05 USDC (x402).
reconcileCompare two versions of a table by key: rows added, removed and changed (with the changed columns). Costs $0.05 USDC (x402).
verify_paymentVerify an on-chain payment without trusting any RPC: did this tx transfer at least this amount of a token (default USDC) to this payee, optionally from this payer?

try_verify_paymentFree: the same verification as verify_payment, limited to 3 NEW claims per client per day (asking again about a claim already checked is always free).
get_verificationFree. Current state of a verification by checkId; re-checks it once its retry or challenge time has passed.
watch_verificationFree for a PAID check: add a callback (https) that receives signed events when requiredLevel is reached, when the answer changes, when it becomes final, or when checking gives up. The service re-checks on its own.

Claims already checked cost nothing; if all of them were, nothing
get_verificationsFree. Up to 50 checks at once (re-checked when due), as rows; format "csv" adds a reconciliation CSV.

Cross-check a seller's signed x402 offer + receipt (offer-and-receipt extension): verifies the signatures (official x402 functions; pin the seller with sellerAddress for EIP-712 or sellerJwk for JWS), checks offer and receipt agree, and returns the exact `claim` to prove with verify_payment.
