How credits are spent​

Mainnet

  • Prove API -> Only the proof_request call costs credits; proof_query does not cost credits.
  • Execute API -> Only the execute_request call costs credits; execute_query does not cost credits.

Testnet

  • Credits are not required for Testnet and uses its own Testnet-API key (visible in the testnet toggle).

Pricing​

  • $0.01 per credit
  • Prove API -> One credit = one proof
  • Execute API -> Credit rate may vary based on usecase. Reach out to us to learn more.

3. Make your first request​

Replace YOUR_API_KEY below and run the two-step flow.

3a. Request the proof​

curl -X POST <https://api.polymer.zone/v1/> \\
  -H "Authorization: Bearer YOUR_API_KEY" \\
  -H "Content-Type: application/json" \\
  -d '{
        "jsonrpc": "2.0",
        "id": 1,
        "method": "proof_request",
        "params": [{
          "srcChainId": 11155420, 
          "srcBlockNumber": 26421705, 
          "globalLogIndex": 15 
        }]
      }'

Response

{"jsonrpc":"2.0","id":1,"result":123456}

Save the numeric result—that’s your jobID.

3b. Query for the proof​

# Repeat every few seconds until status == "complete"
curl -X POST <https://api.polymer.zone/v1/> \\
  -H "Authorization: Bearer YOUR_API_KEY" \\
  -H "Content-Type: application/json" \\
  -d '{
        "jsonrpc": "2.0",
        "id": 1,
        "method": "proof_query",
        "params": ["123456"]
      }'

Final response

{
  "jsonrpc":"2.0",
  "id":1,
  "result":{
    "status":"complete",
    "proof":"base64EncodedProofData..."
  }
}

Base64-decode the proof bytes, convert to hex, and submit them as call-data in your smart contract.

That’s it—your credits are deducted automatically and you can track your daily usage in Polymer Portal.
