The response says which you got: ```text theme={null} x-cache: hit x-cache: miss ``` Bypass it with `fresh=1`: ```bash theme={null} curl 'https://metamanager.dev/inspect?url=https://example.com&fresh=1' ``` A cached response still counts against your rate limit. The limit is about fairness of access, not about our compute. `prompt=` is applied **after** the cache, so switching framework never costs a fresh check. One cached report serves all five frameworks. ## Document size Only the HTML is measured, and reading stops at the ceiling rather than failing outright where possible — `truncated: true` on the report tells you it happened. Everything that matters is normally in ``, so a truncated document usually still produces a complete report. ## Crawling A [site audit](/docs/guides/site-audits) fetches one page at a time with a pause between requests, and backs off further when a site starts returning errors. A declared `Crawl-delay` in `robots.txt` is honoured. | Limit | Value | | :----------------------------- | :---------------------------- | | Requests in flight per audit | 1 | | Minimum gap between requests | 300 ms, or your `Crawl-delay` | | Redirects followed per page | 3 | | Retries on a transient failure | 1 | Each run also has a time budget scaled to its page ceiling. Reaching it ends the audit with what it covered, reported as such rather than as a failure. ## Images Social images are fetched to measure them, and are subject to the same SSRF rules as the page itself — an `og:image` pointing at a private address is not fetched. Only the header bytes are needed for dimensions, so the whole file is not downloaded.
