Proof of existence for files: anchor a SHA-256 hash on Base, look up proofs. Paid with x402.

## Tools (as reported by the server, not verified)

- `find\_proof`: Free. Look up whether a file hash is anchored on Base and when, or read the proof written by a transaction. Pass \`hash\` or \`tx\`. Call it before anchor\_hash to avoid paying for a hash that is already anchored.
- `anchor\_hash`: Paid with x402 \(USDC on Base\). Writes the SHA-256 hash of a file on-chain; the block time becomes the proof of existence. Compute the hash locally and never send the file. The hash, the filename and the payer address become public and permanent. Without a payment in \_meta\["x402/payment"\] the result
