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 + on-chain pointers), CC0 image generation, a daily CC0 market brief, and re-brokered third-party agents. cc0pedia data is CC0."}
