api record

MCP tool calls are free up to 20 per client per day (your first call is always free; invalid arguments are not counted). Plain HTTP also has a free tier: 5 free calls/day/IP on every /v1 endpoint (response shows freeTier.remaining), then x402. With header X-API-Key (prepaid credits, buy once at https://api.moneytools.dev/v1/credits/buy?pack=1000) tool calls use your credit balance instead of the demo quota. Or pay per call over x402 at https://api.moneytools.dev/v1/recommend, https://api.moneytools.dev/v1/precheck, https://api.moneytools.dev/v1/verify, https://api.moneytools.dev/v1/sol-mint,…

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 4 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 7 tools
1 paid 6 never probed 1 of 7 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.

  • x402_gateway_plan unknown 1h ago

    Before paying an x402 seller through the non-custodial MoneyTools Pay Gateway: prechecks the seller (valid x402 terms, OFAC-screened payTo) and returns the gateway URL to call, the price and the gateway fee (max(1% of price, $0.001), charged from prepaid credits only when the seller answers 2xx). Your own wallet always pays the seller directly; the gateway never holds or signs funds. Then call gatewayUrl with header X-API-Key using any x402 client.

_ 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 4f92032f44897884.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/4f92032f44897884/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.

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.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
