API (Beta) - BitProof

Release stage: Private beta / early access

Last updated: March 3, 2026

API access is rolling out in controlled phases. Core endpoints are live. Authenticated v1 features are in early access.

What the API Enables

Timestamp file hashes and get downloadable .bitproof bundles.
Archive public URLs into evidence bundles with screenshot, HTML, PDF, and Bitcoin-anchored proof.
Verify proof bundles against OpenTimestamps / Bitcoin confirmation state.
Integrate BitProof into external systems with API keys and stable response envelopes.

Current Endpoints

Core Endpoints (Live)

POST /timestamp - hash to proof bundle
POST /archive - URL to archive proof bundle
POST /verify - verify content + proof
GET /health, GET /ready, GET /platforms - service status and platform catalog

v1 API (Early Access)

POST /api/v1/timestamp
POST /api/v1/timestamp/file
POST /api/v1/timestamp/batch
POST /api/v1/verify
POST /api/v1/archive

Authentication and Access

Public core flows continue to work without an API key. Authenticated v1 access is issued by API key for controlled rollout, integration testing, and tiered usage limits.

To request beta access, use the support link in the footer and include your use case, expected volume, and whether you need file upload, batch timestamping, or archive integration.

Quickstart Example

Hash-first timestamp request to the live API:

{
  "hash": "0812b186d8bd5a10f7f0f9f3f53f8f4b3224f0f2dcf17e9e5f3d9b7f5c9e1a6c",
  "filename": "example.txt",
  "filesize": 1234
}

curl -sS https://api.bitproof.org/timestamp \
  -H "Content-Type: application/json" \
  -d @payload.json
