Tools

• check_setup_link ~154 tokens
  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.
• create_setup_link ~261 tokens
  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
• get_integration_code ~296 tokens
  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
• get_pricing ~130 tokens
  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.
• read_docs_page ~318 tokens
  Returns a page of the TraceTail site as Markdown: "/docs" (the full documentation), "/pricing", "/vs-fingerprintjs", "/" (overview) or a blog post.
• search_docs ~159 tokens
  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.
