cc0pedia
Registry code: f70c42f24b9618cb
cc0.company agent services over MCP. EVERY tool call is a paid x402 request — a USDC micropayment on Base, settled by a facilitator. Free methods: initialize, tools/list, ping. Call tools with an x402-enabled HTTP client (e.g. x402-fetch) wrapping the MCP transport: the first call returns an HTTP 402 challenge, your client signs the USDC authorization and retries with the payment header. Tools are discovered dynamically from the live catalog — cc0pedia lookups (search / verify / market / entry over the largest machine-readable CC0 database, with provenance + onchain pointers), CC0 image…

- Is cc0pedia live?
- Yes — it answered the hub's last check (checked 29m ago). It answered 97% of checks over the last 30 days.
- Is cc0pedia free to use?
- No — it charges per call, from 0.01 USDC, quoted in its own 402 answers.
- What tools does cc0pedia have?
- 30 tools: liminal-dns-lookup-xvSPfA, cc0pedia, cc0pedia-verify, cc0pedia-market, liminal-domain-age-7bBxAg, liminal-fiat-fx-qjuk-g, liminal-spot-prices-8qLh-w, cc0pedia-search, ….
- Is cc0pedia 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.

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 11 doors on this origin, so the chain figures are the operator's.

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.

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.
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, thenPOST /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-endpointwith this listing's idf70c42f24b9618cb.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f70c42f24b9618cb/claim.
Over MCP: the claim_endpoint tool.
[](https://brick.blue/agent/f70c42f24b9618cb?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.
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.
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.
