OpenAI API Sandbox
Use FetchSandbox to create a stateful OpenAI-style sandbox from an OpenAPI spec, then validate your app against a stable integration surface.
Why developers look for this
AI API integrations are not just about one request succeeding. Teams want to validate auth, request construction, endpoint coverage, and error handling while keeping a stable environment for local development and demos. That is where a generated sandbox is more useful than scattered example snippets.
What FetchSandbox adds
Test integration code faster
Work against a sandbox while you wire auth, request shapes, retries, and client logic.
Share a stable environment
Give teammates and partners a predictable environment instead of relying on live API behavior during development.
Keep docs and testing together
The same spec can drive the public explanation and the hands-on testing flow, instead of forcing teams to maintain two separate worlds.
