Every agent-payable API.

reCAPTCHA v2/v3, hCaptcha, Turnstile. Paid per call via x402 in USDC on Base. No free trial — every call spends a prepaid solver balance.

One RFC 3161 timestamp receipt over a digest you supply. No account and no API key: the response is the whole deliverable. Your data is never sent - only its hash - and nothing about the request is retained here.

Receipt-level comparison between a public transaction hash and caller-provided payment expectations.

Verified payment receipt image (1200x675 PNG) for an XRP Ledger payment, drawn only from the validated ledger: delivered amount, sender, recipient, destination tag, ledger, close time, result, optional expectation checks, and a QR code to the public explorer. Only final outcomes are drawn; not-found or unvalidated transactions are not charged. Useful for showing a person proof that a payment arrived.

Your own settled calls in the shape a finance system posts: one row per payment with what was bought, the amount settled, the quoted ceiling where one applied, and the evidence - settlement transaction, sha256 of the bytes delivered, and the on-chain attestation id where one exists. Keyed to the wallet that pays for the call, so nobody can read another wallet's payables; no account, no export request, no support ticket. Requires an EIP-3009 payment (USDC on Base, Polygon, or Arbitrum).

Receipts for agent payments. Send a Base USDC tx hash, get a settlement proof on Arc with a public verify link. $0.02 USDC on Base. The paying wallet must be the sender or recipient of the USDC transfer (403 otherwise, not charged). Idempotent: an already-recorded tx returns status "existing" with no new Arc write. You are only charged when a proof is returned. Site: https://liquidlogicx.com
