Full-text search over the public OpenTrain job marketplace. This endpoint is tokenless — no Authorization header needed — and CORS-enabled (Access-Control-Allow-Origin: *), so it works from browsers, scripts, and agents without any onboarding. Responses are cached at the edge (Cache-Control: public, s-maxage=300, stale-while-revalidate=3600). For filter values to offer in a UI, fetch GET /jobs/facets first. To track marketplace changes incrementally, poll GET /jobs/changes. Requirements: none — no token, no scope, no feature flag. Rate limited to 120 requests/minute per IP.
