api record

Plumb Data Exchange: verified table data jobs. Paid tools cost $0.05 USDC on Base per call, paid with x402 (an x402-capable MCP client pays automatically after the first call returns the payment terms). Results are independently verified before release; a job nobody completes in time is refunded. If a paid call returns a jobId instead of a result, call get_job with the jobId and accessToken. Payment verification: verify_payment ($0.02 USDC), try_verify_payment (free, 3/day), get_verification (free poll).

_ is it live, free and safe measured by this hub
Is plumb-data-exchange live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is plumb-data-exchange free to use?
No — it asks for a key or a login before it will serve.
What tools does plumb-data-exchange have?
7 tools: convert_to_csv, deduplicate, reconcile, verify_payment, try_verify_payment, get_verification, get_job.
Is plumb-data-exchange 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.

  • get_job auth-required 1h ago

    Free. Status and (once verified) the result of a paid job, using the accessToken its paid call returned.

  • verify_payment unknown never probed

    Verify an on-chain payment without trusting any RPC: did this tx transfer at least this amount of a token (default USDC) to this payee, optionally from this payer? Proven by Plumb (Base via proof-backed L1 checkpoints, Ethereum via a light client). Bound to the exact transfer (log index); returns the proof level, the evidence to re-check, and an Ed25519-signed receipt. Never answers not_paid while a payment is still pending. Costs $0.02 USDC (x402).

_ try it 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 abc61d5416da46b1.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/abc61d5416da46b1/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/abc61d5416da46b1/badge.svg)](https://brick.blue/agent/abc61d5416da46b1?ref=badge)

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 know
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.
