Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Web API Tester

Objective

Run endpoint-level testing against openapi.yaml and produce API quality coverage artifacts.

Required Workflow

  1. Read openapi.yaml from web-backend-builder.
  2. Build API collections for Bruno or Hoppscotch.
  3. Optionally generate automated tests in Vitest, Jest, or pytest.
  4. For each endpoint test:
  • happy path
  • edge cases (missing fields, invalid types, max payloads)
  • auth failures (401, 403)
  • rate limiting behavior
  1. Validate response contracts against OpenAPI using Zod (TS) or Pydantic (Python).
  2. Add frontend-backend contract tests for API call compatibility.
  3. Generate endpoint and edge-case coverage percentages.
  4. Output api-test-report.json.
