Does it support YAML as well as JSON?

Yes. It tries JSON first, then parses YAML locally in the browser.

Is this a full OpenAPI validator?

No. It focuses on endpoint inventory and practical readiness checks, not every schema rule in the OpenAPI specification.

Why flag missing operationId?

SDK generators, docs tools, and API clients often rely on stable operation IDs for clean method names.

Are private API specs uploaded?

No. The spec is parsed locally and can be exported as Markdown, JSON, or CSV.

Prepare an API for SDK generation

Find missing operation IDs, summaries, tags, and success responses before generating client libraries.

Review internal API surface area

Export a path and method inventory for product, QA, security, and platform cleanup meetings.

OpenAPI Endpoint Auditor - local API spec inventory

Audit OpenAPI JSON or YAML for endpoint coverage, missing operation IDs, security gaps, and weak response documentation.

What this tool does

OpenAPI Endpoint Auditor turns an OpenAPI 3.x JSON or YAML file into a local endpoint inventory. Paste a spec or upload a file and the tool lists every path, method, operationId, tag, summary, response code set, parameter count, security declaration, deprecated flag, and issue note. It highlights missing operation IDs, missing summaries, endpoints without global or operation-level security, deprecated operations, and methods that do not document a 2xx response. The report is useful before SDK generation, API documentation launches, partner handoff, security review, QA planning, and cleanup of older API surfaces. Everything runs in the browser, so private internal API specs do not leave the machine.

Tool details

Input: Files + Text + Numbers; The page exposes text boxes, numeric controls, file pickers, or structured inputs depending on the tool.
Output: Live result + Copy + Download; The result area focuses on usable output, with copy, download, or preview actions when supported.
Privacy: Browser-side processing; The main tool logic does not call an external API, so inputs normally stay in the current tab.
Save / share: Shareable URL state; Key settings are encoded in the URL so another person can reopen the same setup.
Performance budget: Initial JS <= 118 KB; No WASM budget is declared, keeping the tool quick to open on mobile.
Best fit: Developer & DevOps · Developer; Category and role tags drive related tools, internal links, and quick fit checks.

How OpenAPI Endpoint Auditor fits into your work

Use it in the small gaps between coding, reviewing, debugging, and shipping.

Developer jobs

Formatting, validating, shrinking, or inspecting code-adjacent text.
Preparing snippets for documentation, tickets, commits, or handoff.
Checking a small payload quickly without switching tools.

Developer checks

Run irreversible transforms like minify or obfuscate on a copy.
Keep secrets out of pasted snippets unless the tool explicitly stays local.
Use your normal tests or linter before shipping transformed code.

Real-world use cases

Prepare an API for SDK generation
Find missing operation IDs, summaries, tags, and success responses before generating client libraries.
Review internal API surface area
Export a path and method inventory for product, QA, security, and platform cleanup meetings.

Common pitfalls

Generating SDKs from specs with missing operation IDs and then hand-fixing method names later.
Treating a rendered Swagger UI page as complete without checking security and response coverage.

Privacy

API specs can reveal private paths and data models. This tool parses them locally and does not upload the file.
