OpenAPI → Code Snippets

Paste an OpenAPI (3.x) spec (JSON or a practical YAML subset) to extract endpoints. Select an operation to generate cURL, Fetch, Axios, and Python snippets.

  • Paste OpenAPI/Swagger spec (JSON or YAML).
  • Pick an endpoint and generate cURL/Fetch/Axios snippets.
  • Perfect for API docs and client code samples.
  • Share results: Generate a secure link to share your current input and results with teammates — nothing is uploaded to any server.

How to use the OpenAPI → Code Snippets Generator

Paste or load an OpenAPI 3.x (or Swagger 2.0) spec in JSON or YAML, browse the operations, pick one, and generate a ready-to-run code snippet in your target language: cURL, fetch, Axios, Node.js, Python requests, Go, Java (HttpClient), C#, Ruby, or PHP. The URL, method, path / query parameters, headers, request body, and security scheme are filled in from the spec. Useful for trying a new API, bootstrapping a client, generating documentation samples, or QA test recipes. Runs locally; the spec never leaves your browser.

When to use it

How to use it

  1. Paste or load your OpenAPI / Swagger spec (JSON or YAML).
  2. Browse the operations list grouped by tag; pick one.
  3. Fill in any parameters you want as concrete values (the form uses examples from the spec).
  4. Pick the target language and copy the snippet.
  5. For a Postman collection of the entire spec, use the OpenAPI → Postman Exporter.
  6. For a single ad-hoc request without a spec, use the Request Snippet Generator.
