Independent Verification

The response includes instructions for verifying without trusting Treeship:
  1. Get the public key: curl https://api.treeship.dev/v1/pubkey
  2. Save the payload: The recreate_payload field contains the exact JSON that was signed
  3. Verify: Use OpenSSL or any Ed25519 library to verify the signature
