https://x402-retire-git-feat-paid-indexing-gate-and-openapi-carbonmark.vercel.app/api/catalogShares a payout wallet with 1 other endpoint — its adoption is attributed from that shared wallet's traffic, not earned exclusively.
Live snapshot of the most liquid carbon credits retirable on Base: the top 3 Klima Protocol carbon classes and the top 3 Carbonmark marketplace listings, with USDC-per-tonne prices and tonnes available. Additionally, the additional endpoints to quote and retire carbon are included; query those endpoints for further discovery, quotes, and retirements. Query /.well-known, /openapi, and /discover to get started.

How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).
Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

Payout address changed 1 time, last on 10/6/2026
- 0x6ada…2E39 → 0xf624…2d0e (base) · 10/6/2026
A changed payout address is worth a second look — it can be routine, but it is also how a hijacked listing redirects funds.
This payout wallet is shared: figures cover all 2 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
Linked by wallet — likely same operator
On-chain agent identity and the x402 endpoint that shares its settlement wallet.
