api record

Census lists electric and plug-in hybrid vehicles for sale in the United States. Call list_models to learn make and model spellings, search_listings to find cars (give a zip for nearby results), get_listing for one car's price history. Every record carries the dealer's own page in seller.url; send people there to buy. Facts marked estimated are not the manufacturer's own figure. Results are as of the as_of timestamp.

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.

  • search_listings open 13h ago

    Search every electric and plug-in hybrid vehicle listed for sale in the United States that Census tracks — new, used and certified, from dealers' own sites and manufacturer inventory. Returns matching listings with price, mileage, location, the dealer's own page, and the EV facts the site stands behind (battery kWh, EPA range, charge port, heat pump, DC fast charging), each marked estimated when it is not the manufacturer's own figure. Inventory is as of the `as_of` timestamp in the result.

_ 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 d1afec74a285b793.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d1afec74a285b793/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
70%

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.
