Developer sandbox — API key + curl

Grab an ephemeral sandbox API key and exercise the real Agent Commerce endpoints with curl. Certify drop zone is here too. Everything runs in test mode — real signatures, zero persistence, no charges.

Looking for a click-through product demo? /agent-commerce/demo runs the full policy → receipt → verify flow with no key management. Or start at /try for all three pillars.

Certify an artifact — no account required

Drop any file to compute its SHA-256 fingerprint and check the public registry. Sandbox certifications are test-mode only — rate-limited, limited retention, and clearly distinct from production certificates.

Anonymous sandbox includes a limited number of test certifications so you can see the full certification loop before creating an account.

Sandbox vs. production

Your sandbox API key

Use this key to call the Agent Commerce API in sandbox mode. No login required. Sandbox keys use the cdp_test_ prefix.

Sandbox environment · limited retention · test-mode outputs only · not equivalent to a production account

Where to start

Curl reference + open-source SDK

The Agent Commerce SDK, MCP server, and integration examples are in the public repo. Clone it, run the examples with your sandbox key, and build on top of the real API.
