Upload an OpenAPI 3.x spec (JSON or YAML) and Yorker generates a ready-to-run HTTP monitor for every supported operation. Path parameters are substituted with example values from the spec, and each generated monitor carries an `openapi_conformance` assertion that links it back to the source spec so response validation targets the right operation. Re-running generation is idempotent — operations already covered are skipped.

Available in the web UI under **API Specs** on the monitors dashboard.
