Create a monitor
Start watching a keyword set. Matching is literal, so include every spelling people use — the name, the domain and the @handle. The first scan runs on the next cron tick.
REST
/api/v1/monitorscurl "https://herculradar.com/api/v1/monitors" \
--request POST \
--header "Authorization: Bearer hr_live_…" \
--header "Content-Type: application/json" \
--header "Idempotency-Key: $(uuidgen)" \
--data '{"name":"Acme","keywords":["Acme","acme.dev"]}'MCP
Tool name create_monitor. It takes the same input and returns the same { data, meta } envelope as REST, because both call the same function.
Start watching a brand, product or competitor. Include every spelling people actually use — the domain and the @handle as well as the name — because matching is literal.

}Authorization
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.
