OpenAPI Viewer

Paste or upload an OpenAPI or Swagger spec in JSON or YAML and browse its endpoints, parameters, request bodies, and response codes in a searchable, readable layout instead of scrolling through raw spec text. It auto-detects OAS3 versus Swagger 2, and a simple search box lets you jump straight to an endpoint by path, operation ID, or tag rather than hunting through a massive file. This is a read-only viewer, not a validator: it renders specs that parse successfully even if they're technically non-compliant in places, so a dedicated OpenAPI linter is still the right tool for strict spec validation. It also doesn't send any requests; once you've found the endpoint you're looking for, the companion HTTP Request Builder is where you'd actually try calling it.
