_ usage and payments 30 days

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 stands behind 50 doors on this origin, so the chain figures are the operator's. How it is counted.

get_listing_intel reads open 6h ago

Audit your own x402 listings against the live Bazaar catalogue. Authenticity scoring separates genuine demand from self-traffic (the catalogue's highest-volume listings are frequently a merchant calling itself), listing-health diagnostics explain why a listing takes no paid calls, and price-band guidance is drawn from what measurably sells. Includes your revenue percentile across all indexed merchants. [PAID: $1 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

get_market_history reads open 2h ago
The x402 Bazaar as a time series, reconstructed from our own daily snapshots. Coinbase's discovery API returns only the catalogue as it is right now - it has no archive. This returns per-day ecosystem GMV, merchant and listing counts, price-band distribution and median/P90 pricing; per-merchant lifecycle with first-seen, last-seen and departure; every observed price change with date and magnitude; and the biggest movers ranked by change in unique paying wallets rather than call count, because call volume is trivially inflated by a merchant calling its own endpoint. The free current-snapshot view is at /state-of-x402. [PAID: $25 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

_ 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
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.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 61a152fb3296c687.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/61a152fb3296c687/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/61a152fb3296c687/badge.svg)](https://brick.blue/agent/61a152fb3296c687?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

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.
