What it can do
| Tool | What it says it does |
|---|---|
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… |
convert_to_csv | Convert a table to CSV without changing any value; verified by round-trip. Costs $0.05 USDC (x402). |
credential_status | Free. The exchange's on-ledger ProvenPayer credential (XLS-70): issued to an XRPL account after 2 settled, Plumb-proven payments to the house; readable by any seller with ledger_entry. Returns the account's standing, the issued credential (with the CredentialCreate hash, provable with plumb-xrpl)… |
deduplicate | Remove duplicate rows by exact key, keeping the first or last, and report conflicting columns per group. Costs $0.05 USDC (x402). |
get_job | Free. Status and (once verified) the result of a paid job, using the accessToken its paid call returned. |
get_verification | Free. Current state of a verification by checkId; re-checks it once its retry or challenge time has passed. |
get_verifications | Free. Up to 50 checks at once (re-checked when due), as rows; format "csv" adds a reconciliation CSV. |
prove_xrpl_transaction | Prove any XRP Ledger transaction without trusting a server: validator-list quorum, hash links, rebuilt tx tree. Returns full fields, metadata (balances, escrows, channels, credentials as of the tx), quorum evidence and a signed receipt. Unvalidated tx keeps your payment. |
reconcile | Compare two versions of a table by key: rows added, removed and changed (with the changed columns). Costs $0.05 USDC (x402). |
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). Holders of the exchange's on-ledger ProvenPayer credential get more: pass xrplProof (see credential_status). |
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… |
verify_payments_batch | Verify up to 25 payments in one call for $0.25 ($0.05 when every claim is on the XRP Ledger) USDC (x402): give `claims` (same fields as verify_payment) or `csv` (header: chain,txHash,payee,token,minAmountRaw,payer,logIndex,invoiceId). Claims already checked cost nothing; if all of them were… |
watch_verification | Free 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. |
what_should_i_build | What should I build? x402 agent demand by category from public chain data (Base USDC + XRPL), with fake demand removed (testers, sellers paying themselves, loops; wallet fleets counted as one buyer) and gaps ranked (repeat buyers per seller). Rolling 7 days, refreshed every 2 h. Signed answer with… |
In its maker's words
Verified table jobs and RPC-free payment verification (Base/Ethereum). Pay per call via x402.
