RFC 3161 timestamp receipt
timestamp_receiptSubmit a SHA-256 digest and receive a Time-Stamp Authority's signed RFC 3161 token over it: evidence that the data you hashed existed at that time, verifiable against the authority without trusting or contacting this service. Hash your data yourself - it never leaves your side. Costs 0.05 USDC per call, paid over x402. No account, nothing stored here afterwards.
