Registry code: d586243da1dc3f46

api record

Use these read-only tools to research evidence-backed business changes across supported jurisdictions. Start with compact lead search, expand only selected event IDs into primary-source evidence, and inspect coverage before treating no-match as no activity. Effective time is when an event happened; observed time is when this platform learned it.

Preserve exact suites by default. Request building scope only when the user wants all premises at one property.

_ is it live, free and safe measured by this hub
Is business-change-intelligence live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is business-change-intelligence free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does business-change-intelligence have?
5 tools: get_changes_since, get_location_timeline, get_business_event_evidence, get_business_change_coverage, find_business_change_leads.
Is business-change-intelligence 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.

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.

  • find_business_change_leads reads 0.1 USDC paid 15h ago

    Find previously unknown businesses or locations with recent license, permit, inspection, ownership, opening, closure, or tenant-transition signals. Use for market research, sales prospecting, expansion tracking, and location intelligence. Results are compact by default and always distinguish regulatory leads from confirmed public status. Costs $0.10 per successful call when x402 is enabled.

_ 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 d586243da1dc3f46.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d586243da1dc3f46/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/d586243da1dc3f46/badge.svg)](https://brick.blue/agent/d586243da1dc3f46?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
90%

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.
