}⚪verify_payment(chain, txHash, payee, token, minAmountRaw, ...)
Verify 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? Proven by Plumb (Base via proof-backed L1 checkpoints, Ethereum via a light client). Bound to the exact transfer (log index); returns the proof level, how long a Base checkpoint can still be challenged, the evidence to re-check, and an Ed25519-signed receipt. Never answers not_paid while a payment is still pending; abstains (unverifiable) whenever the proof is incomplete. Costs $0.02 USDC (x402); asking again about the same claim costs nothing. Optional requiredLevel (releasable or not) and callbackUrl (signed events when the level is reached, the answer changes, or checking gives up).

Verify up to 25 payments in one call for $0.25 USDC (x402): give `claims` (same fields as verify_payment) or `csv` (header: chain,txHash,payee,token,minAmountRaw,payer,logIndex). Claims already checked cost nothing; if all of them were, nothing is charged. Returns one row per claim (format "csv" adds a reconciliation CSV).

}🟢check_x402_receipt(receipt, offer, sellerAddress, sellerJwk, checkId)
Free. 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. Pass that verification's checkId to learn which side failed.
