api record

Free, keyless tools for Obolpay Gateway (paid data over the x402 protocol; x402™ is a trademark of LF Projects, LLC.): discover (manifest), preview (evaluate before paying; pass types to scope), balance (account balance lookup), verify_receipt (proof-of-purchase check). Purchasing itself uses the standard x402 HTTP 402 flow at /api/v1/protected-data — never send private keys anywhere.

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.

  • preview unknown never probed

    Free preview of the paid dataset so you can evaluate BEFORE paying (trustless). Optionally pass `types` to scope the preview to the categories you would actually buy (?types=). No invoice is created; to purchase, GET /api/v1/protected-data and follow the 402 challenge.

    mcp-tool

  "type": "object",
  "properties": {
    "types": {
      "type": "array",
      "items": {
        "type": "string"
      },
      "description": "Optional category filter, e.g. [\"jp-business-day\"]. Unknown categories are listed in the result's available_types."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • balance unknown never probed

    Look up an existing account balance at this gateway (top-ups are not accepted; a balance comes only from earlier top-ups or automatic refund credits): balance_units, calls_remaining, next_nonce and the voucher message to sign. Read-only. Signing and spending happen on YOUR side with YOUR key — this server never asks for a private key.

    {
  "type": "object",
  "required": [
    "address"
  ],

    "address": {
      "type": "string",
      "description": "0x… EVM address"
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • verify_receipt unknown never probed

    Verify a signed purchase receipt issued by this gateway: recovers the EIP-191 signer of (message, signature) and checks it equals the server's receipt signer. Anyone can verify — no payment required.

    mcp-tool

    {
  "type": "object",
  "required": [
    "message",
    "signature"
  ],
  "properties": {
    "message": {

    },
    "signature": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 16 lines
  • discover unknown never probed

    Return this x402 gateway's machine-readable manifest: price, token, network, recipient, payment flow, capabilities. Same document as GET /.well-known/x402. No payment required.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
_ 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 c486f8c0dd04e9c6.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c486f8c0dd04e9c6/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
80%

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.
