Create a Firecrawl monitor to watch a page or site for content changes

Documented steps

1. Get an API key from the Firecrawl dashboard and send it as 'Authorization: Bearer fc-...' on every request.
2. POST https://api.firecrawl.dev/v2/monitor with a JSON body: {"name":"...", "schedule":{"text":"every 30 minutes", "timezone":"UTC"}, "targets":[{"type":"scrape","urls":["https://example.com/page"]}]}
3. Schedule accepts either a 5-field 'cron' (minimum interval 5 minutes, e.g. '*/30 * * * *') or a natural-language 'text' (e.g. 'every 30 minutes', 'hourly', 'daily at 9am'). timezone defaults to UTC.
4. Target types: 'scrape' (urls[]), 'crawl' (single url + crawlOptions limit/maxDepth/includePaths/excludePaths), or 'search' (queries[] 1-12 + searchWindow; needs a non-empty top-level goal unless judgeEnabled is false).
5. To receive change alerts, add a 'webhook' object with a required 'url', optional 'headers'/'metadata', and 'events': ["monitor.page", "monitor.check.completed"]. You can also enable email via notification.email.
6. name, schedule, and targets are required; response is MonitorResponse with data containing the new monitor id, status 'active', nextRunAt, and estimatedCreditsPerMonth.
7. Optionally set 'goal' (natural-language change description) and 'judgeEnabled':true so the AI judge only flags meaningful changes and ignores noise.
