## Tools (as reported by the server, not verified)

- `get\_integration\_code`: The exact install command and code to add TraceTail browser fingerprinting \(a stable visitor ID for each browser, without cookies\) to a web app built with the given framework, with where each file goes. Works without an API key \(keyless mode, no sign-up\); pass the site's public API key to fill it in
- `search\_docs`: Searches TraceTail's documentation, pricing, comparison and blog for a topic \(e.g. "next.js", "rate limits", "ad blockers", "GDPR", "server-side verification"\) and returns the matching sections with their URLs.
- `read\_docs\_page`: Returns a page of the TraceTail site as Markdown: "/docs" \(the full documentation\), "/pricing", "/vs-fingerprintjs", "/" \(overview\) or a blog post.
- `get\_pricing`: TraceTail's prices and limits \(1,000 identification requests free every month, then $0.10 per 1,000\), with the monthly cost at a given volume and the same volume on Fingerprint \(FingerprintJS\) for comparison.
- `create\_setup\_link`: Gets TraceTail API keys for the person you work for: returns a link to give them, where they sign in with an emailed code and add a card or continue without a card, and a token. Then call check\_setup\_link with its id and token every few seconds: once they've finished, it returns an API key for each
- `check\_setup\_link`: Where a setup link stands. The first check after the person finishes returns the API keys \(and the server key, if requested\); they are not shown again. While they're still on the page, check again every few seconds.
