api record

TraceTail is a browser fingerprinting API: its JavaScript SDK gives each browser a stable visitor ID (over 99.5% accuracy, no cookies, the same ID in incognito). To add it to an app, call get_integration_code with the app's framework. Use search_docs and read_docs_page for anything else in the documentation, get_pricing for costs, and create_setup_link with check_setup_link to get the site's API keys from the person you work for. Without an API key (leave out data-api-key or apiKey) the SDK runs keyless: it computes the visitor ID in the browser and sends nothing, so it works immediately with…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • read_docs_page auth-required 10h ago

    Returns a page of the TraceTail site as Markdown: "/docs" (the full documentation), "/pricing", "/vs-fingerprintjs", "/" (overview) or a blog post.

    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 unknown never probed

    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 free, 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 site (and a server key if you asked), once.

  • check_setup_link unknown never probed

    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.

  • get_integration_code unknown 10h ago

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 45ccc84049924509.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/45ccc84049924509/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
