How this service works
Deterministic CSV, URL, text and PDF utilities sold per call in USDC on Base, plus /verify_receipt: an independent sha256 check that returns a citable receipt id (GET /receipt/{id}) any third party can re-read later.
Output
Returns a JSON object containing: receipt_id (unique citable identifier), sha256 (observed hash), expected_sha256 (originally recorded hash), match (boolean indicating integrity), issuer (Ethereum address of the certifier), issued_at (ISO 8601 timestamp), source (type and reference URL of the original artifact), bytes (file size), label (human-readable artifact name), and verify_url (permanent public link to re-read this receipt).
Example use cases
Audit a software release artifact
“I just downloaded the v1 release tarball and I have the transaction hash 9f2c1d4a7b6e8035 — can you pull up the Textdock receipt and tell me whether the SHA256 matched and who certified it?”
Cite a document integrity certificate
“I need a citable reference showing that our contract PDF was verified last October — the tx_hash is 7a3f2b9c1e4d6081. Can you retrieve the receipt and give me the receipt_id and verify_url?”
Third-party audit of a published artifact
“Our compliance team wants to independently confirm that the data file we published hasn't changed — can you check the Textdock receipt using tx_hash a1b2c3d4e5f60789 and tell me whether the hash matched, the timestamp, and the issuer address?”
Technical details
Endpoint
GEThttps://textdock.ggez.my.id/verify_receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you already have a Textdock-issued transaction hash and need to retrieve or cite the associated SHA256 content-integrity receipt — for example, during audits, compliance checks, or to provide third parties with a permanent, independently readable verification link. Prefer this over re-running a hash check when you need a historical record tied to an on-chain issuance event.
Side effects
- Invalid or unknown tx_hash returns 404 or empty result
- Malformed tx_hash string causes 400 bad request
- Receipt not yet indexed if called immediately after issuance
- Network or service unavailability returns 5xx error
- tx_hash belonging to a different service or contract returns no match
