OpenAPI endpoint summarizer

Paste OpenAPI JSON or simple YAML and summarize methods, paths, tags, and descriptions.

Inputs stay in your browser. Supports OpenAPI JSON and simple YAML with common paths/method structures.

Supports a bounded JSON and simple YAML paths subset, not full OpenAPI validation.

How to use this tool

Paste OpenAPI JSON or simple YAML and summarize methods, paths, tags, and descriptions.

Extract endpoints from OpenAPI JSON or supported simple YAML structures. Get a text list and CSV with method, path, tag, and summary fields.

💡 3 Quick Steps to Get Started

1. Paste Specification

Enter a JSON or simple YAML document containing paths.

2. Parse Endpoints

Extract HTTP methods and paths, the first tag, and summary; operationId is used if summary is absent.

3. Review or Download

Review the text list or download CSV with method, path, tag, and summary columns.

When it helps

Useful for API inventory, documentation review, and handoff.

Workflow and limits

Enter a JSON or simple YAML document containing paths.

Extract HTTP methods and paths, the first tag, and summary; operationId is used if summary is absent.

Review the text list or download CSV with method, path, tag, and summary columns.

This is not a full specification validator. It does not summarize parameters, response statuses, or security settings, and has no search-filter interface.

YAML support uses a simple parser, not every YAML feature. Use JSON if parsing fails. Specification processing runs in the browser.
