`check_x402_receipt`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.	Free.

`try_verify_payment`Free: 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).

`verify_payment`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, XRP Ledger via a quorum of Ripple's validator list: RLUSD, XRP or any issued currency). 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) ($0.002 for an XRP Ledger payment); 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).
