Quick Start (`/beat/timestamp`)

Replace <your-lowercase-sha256-hash> with a real 64-character lowercase SHA-256 hash.

curl -X POST https://beats.provenonce.dev/api/v1/beat/timestamp \
  -H "content-type: application/json" \
  -d '{"hash":"<your-lowercase-sha256-hash>"}'

Test Beats in 5 Steps

  1. Generate a SHA-256 hash locally for any file or payload.
  2. POST it to /api/v1/beat/timestamp.
  3. Confirm response includes on_chain.tx_signature and signed receipt.
  4. Open the Solana explorer URL from the response (devnet) and confirm the transaction exists.
  5. Fetch /api/v1/beat/key and verify the receipt signature offline.
Expected response fields: timestamp.hash, timestamp.anchor_index, on_chain.tx_signature, receipt.signature
