CDR.fyi tracks nearly $12.4B and ~49.4M tonnes of durable (100+ year permanence, engineered) carbon removal across biochar, DACCS, BECCS, enhanced weathering, mineralization, and marine CDR, real market data, credited in full below. EcoWealth's own retirements settle a different credit class (nature-based, sub-100-year, via Klima/Regen Network) at sub-cent micro-scale, which their own methodology structurally excludes on two independent grounds. This page states that plainly, then offers two small, honest ideas about making CDR.fyi's already-good public data more agent-consumable, not a pitch for inclusion.
docs.cdr.fyi/methodology: "CDR.fyi aggregates purchases, deliveries, and verifications of carbon removed and stored for +100 years." EcoWealth's retirements run through Klima's Retirement Aggregator against a Regen-CFC (nature-based) carbon class, a sub-100-year-permanence instrument by definition, at a 5-cent micro-retirement scale, a fraction of a fraction of the whole-tonne unit their entire schema, pricing vocabulary, and API are built around. Two independent gates, either one sufficient on its own. This package does not propose crossing them.
noindex, and not sent anywhere without explicit review.Credit-first, because the credit is real and unusually clean. Each fact is reproducible with one command: the capability brief has the exact curl lines and byte counts.
agent-card.json (the file that lets an AI assistant use a service correctly), .well-known/x402 (a web-native way for AI agents to pay per use), ai.txt, security.txt all true-404 at 28,695 B, identical to a nonsense-path control. Status tells the truth.api.cdr.fyi/v1/orders returns a real, versioned 401 "Unauthorized: Invalid write key" with zero credentials sent, genuine auth, not a soft-200.Six evidenced findings: the excellent llms.txt, the true-404 discipline, the honest API gate, the one schema gap in the free data, the durability/scale mismatch stated in full, and the pricing survey as public good, each with the exact URL, status, and re-check command.
Read the briefAct one: the real, live probe run for this brief: llms.txt, the true-404s, the honest 401, nothing mocked. Act two: two small concept additions: a public-only stats manifest for the data CDR.fyi already calls free, and an agent-readable price-context object built from their own published, attributed benchmark numbers.
See the demoA public-only agent-card.json and MCP tool schemas covering just the free leaderboard/market-update data, a "Durable-CDR Price-Context Concierge" persona that always attributes and never claims affiliation, and the give-to-get vs. free-proof comparison in full.
Not a comparison meant to declare a winner: CDR.fyi's model and EcoWealth's model solve different problems, and both are defensible.
Public pages (homepage, leaderboards, blog, methodology) are free for anyone, including AI systems: llms.txt says so explicitly. The deeper layer (full order-level history, bulk export, API keys) is earned by contributing your own real transaction data through the Partner Portal, or bought via a paid Team+ tier. Depth is the reward for reciprocity.
Every proof artifact (a settled work packet, a retirement receipt, a contract address) is free and keyless to read, always: reads never gate. Only the write action (claiming work, posting a packet) carries a nominal cost (an EWP key, or five cents via x402). Depth is never withheld; only the act of adding new proof has a floor.
0x76c17C…A14B settles real-world ecological labor on Base mainnet; a share of settled work retires carbon through Klima's gasless relay and the Retirement Aggregator against a Regen-CFC (nature-based, community-forestry) carbon class, the exact instrument CDR.fyi's own "+100 years" durability rule excludes by design, at a micro-retirement scale CDR.fyi's whole-tonne schema has no field for. Neither of those is a defect in either system; it's why this note proposes making CDR.fyi's public data more agent-legible, not proposing our retirements join their tracker.
