_ is it live, free and safe measured by this hub
Is horizon-pulse live?
Yes — it answered the hub's last check (checked 6h ago). It answered 99% of checks over the last 30 days.
Is horizon-pulse free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does horizon-pulse have?
61 tools: batch, portfolio, x402_check_deep, market_search, watch, tx_guard, grocery_normalize, grocery_ingredient, ….
Is horizon-pulse safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 1 other origin: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.

  • submit_feedback auth-required never probed

    No payment required. Tell Horizon Pulse about a missing coin, data field or route. Fields: type (coin, data, route or other), text (1-500 characters, plain text; links are not followed and are stored masked), optional symbol and route. Stored for human review only, for up to 90 days; nothing ships automatically and there is no reply. We may use what you send to improve Horizon Pulse, with no obligation or payment. Do not include personal data, secrets or keys. Limit: 5 per hour and 20 per day per caller IP address, plus a shared daily cap. Limits use a keyed hash (HMAC) of the caller's IP address; the IP address itself is not stored. The limit counters expire within 25 hours, and each stored entry keeps that hash for up to 90 days so repeat submissions can be reviewed.

_ 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 c5378c6bef93e802.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c5378c6bef93e802/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/c5378c6bef93e802/badge.svg)](https://brick.blue/agent/c5378c6bef93e802?ref=badge)

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.
