CarbonClimateBase

Entry point to the x402 Carbon Retirement API on Base. Returns every endpoint you need plus a live snapshot of the top 3 carbon classes and marketplace listings by liquidity. Discover, quote and certificate are free. Retiring is paid: each retirement costs the credit price plus a fee, sent from your own wallet (prepare/retire) or relayed from a signed USDC authorization (prepare-auth + POST actions/retire). Full spec at /openapi.json.

Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check 0xf624…2d0e's payment record before paying it over the free read API. No key, no account.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
