Update a monitor

curl "https://herculradar.com/api/v1/monitors/:id" \
  --request PATCH \
  --header "Authorization: Bearer hr_live_…" \
  --header "Content-Type: application/json" \
  --header "Idempotency-Key: $(uuidgen)" \
  --data '{}'

Tool name update_monitor. It takes the same input and returns the same { data, meta } envelope as REST, because both call the same function.

Change a monitor’s keywords, sources or active state. Only the fields you pass change.

Requires the monitors:write scope. A credential without it gets 403 FORBIDDEN. Resources in projects the credential cannot reach answer 404 NOT_FOUND rather than 403, so ids cannot be probed across tenants.

Send an Idempotency-Key header. A completed response is replayed for 24 hours, so a retry after a timeout cannot create a duplicate.
