api record

Paid API catalog: https://api.xguardgate.com/v1/marketplace/services. Seller onboarding: https://xguardgate.com/sellers. Buy a listed service through its paid endpoint using an owner-authorized wallet and exact spending cap. Give agents capabilities, not reusable credentials. Use xguard_secretless_call or xguard_execute with an exact operation ID, input and operator-issued capability. Never supply a reusable provider key to an agent. xguard_preflight checks policy without execution; xguard_quote explains the price; xguard_verify_receipt verifies signed evidence. Writes need an explicit…

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.

  • xguard_status reads open 40d ago

    Read observed execution/MCP metrics and configuration; empty observations do not imply uptime.

  • xguard_execute unknown never probed

  • xguard_secretless_call unknown never probed

    Call an allowed provider operation with a capability. Enforces scope, call/credit budget and billing before server-side credential injection. Writes require idempotency_key.

  • xguard_verify_receipt reads unknown never probed

    Verify a ProofRail proof and optionally its bound x402 receipt and result digest. Signature validity does not prove source truth.

  • xguard_get_result reads unknown never probed

    Recover a paid public outcome with its payment identifier and original signed quote without execution or another payment.

_ try it over mcp 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 285e28161dad882b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/285e28161dad882b/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.
