Firecrawl handles fetching, diffing, judging, and notifying server-side.

Read <a href=\"json-tracking.md\">json-tracking.md</a> when the user cares about specific structured fields (price, headline, stock flag) and wants per-field diffs.</p>\n<h2>Constraints &amp; tips</h2>\n<ul>\n<li>Each check uses credits for its underlying scrape, crawl, or search, plus optional judging. See <a href=\"https://docs.firecrawl.dev/features/monitoring#pricing\">Monitoring pricing</a>.</li>\n<li>Minimum schedule interval is <strong>5 minutes</strong>. Monitoring is <strong>not available for zero-data-retention teams</strong>.</li>\n<li><strong>Prefer one monitor over repeated one-off scrapes</strong> whenever the user wants the same URL checked more than once.</li>\n<li><strong>Silence temporarily with <code>update --state paused</code></strong>; reserve <code>delete</code> for monitors that are permanently done. (<code>--state</code> is an update flag; <code>--status</code> is the global CLI status flag.)</li>\n<li><strong>Filter check pages with <code>--page-status changed</code></strong> (or <code>new</code>, <code>removed</code>, <code>error</code>) to skip the noise from <code>same</code> pages.</li>\n<li><strong><code>firecrawl monitor run &lt;id&gt;</code></strong> triggers a check immediately — useful for smoke-testing a monitor right after creating it.</li>\n<li><strong><code>--retention-days</code></strong> controls how long snapshots are kept for diffing. Lower it for high-frequency monitors to save storage.</li>\n<li><strong>External email recipients must opt in.</strong> First time they're added, Firecrawl sends a confirmation email and they only receive alerts after they confirm. Team-owned addresses are auto-confirmed. Once a recipient unsubscribes, they must be re-added by the owner for a fresh confirmation email.</li>\n<li><strong>On HTTP 429 / rate-limit errors, back off once</strong>: wait ~30s and retry once. If it persists, stop, report the rate limit as the blocking reason, and delete any monitors created for this task. Never retry in a loop.</li>\n<li><strong>Monitor-triggered scrapes default <code>maxAge</code> to <code>0</code></strong> — every check performs a fresh scrape unless <code>scrapeOptions.maxAge</code> is set explicitly in a JSON payload.</li>\n</ul>\n<h2>See also</h2>\n<ul>\n<li><a href=\"../firecrawl-scrape/SKILL.md\">firecrawl-scrape</a> — one-off scrape; escalate to <code>monitor</code> when checks become recurring</li>\n<li><a href=\"../firecrawl-crawl/SKILL.md\">firecrawl-crawl</a> — one-off crawl; pair with <code>--crawl-url</code> here for recurring crawl diffs</li>\n<li><a href=\"../firecrawl/SKILL.md\">firecrawl</a> — top-level workflow guide</li>\n<li><a href=\"https://github.com/firecrawl/skills/tree/main/skills/build/firecrawl-build-scrape\">firecrawl-build-scrape</a> — building recurring checks into an app instead of running it here</li>\n</ul>\n","files":[{"path":"goals.md","sizeBytes":4744,"isText":true},{"path":"json-tracking.md","sizeBytes":2598,"isText":true},{"path":"SKILL.md","sizeBytes":5511,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
