Swagger · Postman · cURL Risk Discovery

API tests from specs — and risks from a live cURL.

Upload Postman or OpenAPI/Swagger to generate NLP coverage. Or paste one working cURL to discover validation, auth, boundary, and protocol failures — run in cloud or on your local agent, then promote failures into regression and Engineering Memory.

Postman · Swagger · Impact — interactive demo

The same import panel from the homepage feature theater: import a collection or OpenAPI file, see generated coverage, then watch schema drift flag linked tests.

Postman JSON → NLP suite with auth and chaining preserved
OpenAPI YAML/JSON → happy + negative + boundary + auth
Schema changes trigger impact analysis on linked tests

API Risk Discovery

Have a working request but no suite yet? Paste one cURL. TestNeo expands it into deterministic validation, boundary, auth, schema, and protocol variants — no LLM inventing attacks — then scores API Confidence. Failures promote to NLP regression and Engineering Memory so the next PR can WARN.

Discover → Run (cloud or local agent) → Promote & remember
Protocol signals: HTML-from-JSON, soft method handling, security-header hygiene
Export Confidence Brief or Postman collection
Complements Swagger/Postman generation — not a replacement

From a spec

Postman / OpenAPI → broad NLP coverage and schema impact.

From a live cURL

Risk Discovery → break assumptions on one endpoint, then feed RI.
