Warns about the mistakes that silently break reporting: an unrecognised medium that drops traffic into Unassigned, casing that splits one source into several report rows, PII in a campaign name. Pure string work: nothing is fetched and nothing is stored. Returns { url, normalized, channel, issues[] with level, field and message }. Limit: None. The work is local and costs nothing.. Allow up to 10s for a response. Free, no account, no API key.

Returns a signed link to the image that expires in about 24 hours; download the bytes if you need to keep them. No watermark and no height cap. Cannot capture anything behind a login. Returns { imageUrl, expiresAt, bytes, width, height, deviceType }. Limit: 10 runs per hour per IP. Allow up to 90s for a response. Free, no account, no API key. Pass `url` to start a run. A slow run answers with `{ status: "pending", runId }` instead of a result: call this same tool again with just that `runId` to collect it, as many times as it takes. Collecting costs no rate-limit slot.

Runs the full suite: robots.txt rules per AI crawler, a live firewall test that requests the page as GPTBot, JavaScript dependency, llms.txt, headings, structured data, and author identity. Returns a score out of 100 with a grade, a score per category, and a finding per check with why it matters and how to fix it. Use this for a whole-page verdict; use check_robots_txt_for_ai when the question is only about crawler access. Returns { ok, report: { score, grade, scoredOutOf, categories[], findings[] with why and fix, detection }, cached, ageSeconds }. Limit: 10 runs per hour per IP. Allow up to 75s for a response. Free, no account, no API key. Pass `url` to start a run. A slow run answers with `{ status: "pending", runId }` instead of a result: call this same tool again with just that `runId` to collect it, as many times as it takes.

Reads every icon declaration in the page head, then fetches each one, the web app manifest, and the implicit /favicon.ico, and identifies the real format and pixel dimensions from each file's header bytes. Catches the failures a status-code check misses: a catch-all route answering an icon path with HTML at HTTP 200, a sizes attribute that disagrees with the file, an icon served over http on an https page. Use this when a favicon is missing or blurry; use check_social_preview for the image that appears when a link is shared. Returns { hasWorkingFavicon, tabIcon, icons[] with format, dimensions, bytes and problem, manifest, themeColor, checks[] with id, status and fix, counts }. Limit: 60 runs per hour per IP. Allow up to 30s for a response. Free, no account, no API key.

Also runs a firewall test, because CDN-level blocks stop crawlers before robots.txt is ever read. This is the access-scoped view of check_ai_visibility. Returns { ok, report: { accessScore, crawlers[] with the rule that decided each verdict, firewall, findings[] }, cached, ageSeconds }. Limit: 10 runs per hour per IP. Allow up to 75s for a response. Free, no account, no API key. Pass `url` to start a run. A slow run answers with `{ status: "pending", runId }` instead of a result: call this same tool again with just that `runId` to collect it, as many times as it takes.

Returns a per-platform preview (title, description, image) plus the findings for tags that are missing, truncated, or the wrong size. Returns { ok, report: { previews[] per platform, tags, summary, findings[] }, cached, ageSeconds }. Limit: 10 runs per hour per IP. Allow up to 75s for a response. Free, no account, no API key. Pass `url` to start a run. A slow run answers with `{ status: "pending", runId }` instead of a result: call this same tool again with just that `runId` to collect it, as many times as it takes.

One fetch, no rendering and no crawl, so it answers in about a second. A site behind bot protection is reported as blocked rather than as empty. Returns { platformName, theme, apps[], fonts[], analytics[], hosting[], renderMode, url, status, fetchedAt }. Limit: 60 runs per hour per IP. Allow up to 30s for a response. Free, no account, no API key.

Lists every image with the alt it has today, the suggested alt, whether it looks decorative, and why any image was skipped. Up to 10 images per run go to the model. The suggestions are drafts for a human to review. Returns { images[] with src, hadAlt, currentAlt, suggestedAlt, isDecorative, skippedReason; counts; model }. Limit: 10 runs per hour per IP. Allow up to 90s for a response. Free, no account, no API key. Pass `url` to start a run.

The markup is model-written from the page's own content and should be reviewed before it is published. Returns the block ready to paste into a <script type="application/ld+json"> tag. Returns { ok, report: { detectedType, jsonLd, jsonLdString, validation: { findings[], passed }, model } }. Limit: 10 runs per hour per IP. Allow up to 75s for a response.

Inventories the site from its robots.txt, sitemaps, and homepage links, then writes an index file and a full file with page content inlined. Deterministic: no model is involved, so two runs over an unchanged site produce the same bytes. Returns the file contents ready to write to disk. Returns { ok, report: { siteName, llmsTxt, llmsFullTxt, pagesDiscovered, pagesIncluded, truncated }, cached, ageSeconds }. Limit: 10 runs per hour per IP. Allow up to 75s for a response.
