Quickstart & Execution

cURL (20 Free Calls/Day • Zero Authentication Required)

curl -X POST https://api.code402.dev/v1/tools/crypto-ticker/call \
  -H "content-type: application/json" \
  -d '{"symbol":"btc"}'

No API key needed for the free daily tier. When daily quota exhausts, the endpoint replies with HTTP 402 Payment Required specifying the exact USDC amount. Machines sign an EIP-3009 transfer on Base L2; human engineers buy card credits. Every paid execution returns a cryptographically signed XDR-1 receipt for zero-knowledge audit trails.
