About OpenAPI to mock
Convert an OpenAPI 3.x JSON document into a validated static socket.help mock configuration.
When to use it
Start a small mock from an existing API contract.
OpenAPI paths /users/{id} become mock routes /users/:id.How to use it
- Paste an OpenAPI 3.x JSON specification.
- Generate response examples and inspect the routes.
- Copy the configuration into the Mock REST API editor and create the endpoint.
Limits & privacy
Static JSON and text responses only. Up to 20 routes and 64 KiB input. Supports local response/schema references, explicit examples, and basic object, array, enum, and scalar schemas. No remote references, inference, live requests, or stateful behavior.
Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
