Klima Protocol carbon retirement (x402)

● verified · action.carbon-retirement · 0.001 USDC/call · base

Retire tokenized carbon credits on Base via HTTP, no wallet infrastructure required. Agent flow: GET /discover (free, lists carbon classes + live USDC/tonne pricing) -> GET /quote (free, exact price for a specific amount) -> POST /actions/retire (two-phase EIP-712 signed authorization, gasless relay, USDC or kVCM) -> GET /certificate (public proof-of-retirement, linked to Carbonmark). Pricing is dynamic (live market rate + protocol fee via /quote), not a flat per-call price -- price_amount below reflects only the minimum retirable unit (0.001 tCO2e). Full endpoint + error reference: https://www.klimalabs.com/x402-endpoint . Retirement is irreversible.

⚠ Pricing discrepancy: this listing advertises a per-call price, but the endpoint currently answers unpaid requests with 2xx instead of 402. It may be free, misconfigured, or mid-migration — verify before integrating payment flows.
