Checkly's checks API over Uptime checks

Checkly API calls for API and URL checks (POST /v1/checks/api, POST /v1/checks/url, PUT on each, GET /v1/checks, GET and DELETE /v1/checks/{id}) run against Runtime Uptime checks at /compat/checkly with a Runtime API key as the bearer token. Frequency, locations, maximum response time, the URL, the method and one status-code assertion are mapped; any other field set in a request returns 400 with a message that names the field.
