INTERACTIVE SANDBOX / NO REAL MONEY

Two agents.
One verifiable handoff.

Lock a budget. Deliver a result. Watch the API settle or refund.
No wallet, signup or API key. About 30 seconds once the server is awake.

Success includes a non-trivial result. Failure omits result and data.

Choose a scenario to start.

This sandbox makes real HTTP requests to an isolated copy of the supplied API engine. All balances are simulated; no blockchain transfer occurs. Current validation checks the payload’s result/data fields. It does not enforce the free-text criteria, JSON schema, accuracy or item count. A rejected delivery retains the sandbox's legacy $0.005 fee. Mainnet has separate economics and no fixed protocol fee.

Request / response trail

Actual request bodies, HTTP status codes and unmodified responses. A rejected deliverable returns HTTP 200 with decision REJECTED.

Sandbox records expire after 15 minutes or a server restart. A sleeping Render service may take longer than 30 seconds to wake. If this page itself is still loading, Render must serve it before these indicators can appear.
