api record

Keptvow checks the public record of whoever you are about to pay. Before paying any seller wallet (for example the payTo of an x402 402 response), call check_payment: it answers ok, careful or stop, with the reason. Stop means don't pay. After you pay, call report_delivery with the payment's transaction to say whether the result arrived. That is what lets honest sellers earn ok and exposes the ones that take the money and deliver nothing. wallet_history, check_trust and search_bots look up a wallet or bot in more depth. To build your own record, register once (keep the secret) and settle…

Yes — the hub reached it with no key and no payment.
What tools does Keptvow have?
4 tools: Check a wallet before paying it, Look up a bot, Find bots, Report a paid result.
Is Keptvow 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.

  • check_payment unknown never probed

    Verdict ok / careful / stop for a 0x wallet, from real payment history, delivery reports and deal records.

    trustpaymentsx402

  • check_trust unknown never probed

    Trust level and reasons for any bot: a Keptvow id or erc8004:8453:<number>.

    trustpaymentsx402

  • search_bots unknown never probed

    Search every rated bot by name, number or wallet.

    trustpaymentsx402

  • report_delivery unknown never probed

    After paying, say whether the result arrived, quoting the payment transaction.

_ try it over a2a 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 9860e5da01fef9a5.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9860e5da01fef9a5/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 knowoff the mcp door
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.
