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.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 4 tools
4 never probed 0 of 4 classified

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.

  • 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
  • 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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address"
  ],
  "properties": {
    "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": {
      "type": "string"
    },
    "signature": {
      "type": "string"
    }
  },
  "additionalProperties": false
}

_ 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
