Fastly stats

Prefer the fastly CLI. Drop to curl only for the seven things the CLI cannot do, listed under Raw API below.

Requires the fastly CLI, jq, and network access to Fastly APIs; raw API examples also require curl. Use the user's locally configured authentication. If authentication is missing, direct the user to a local CLI login or local FASTLY_API_TOKEN configuration, never to paste a key in chat. Keep tokens out of output and avoid shell tracing for authenticated commands.
