Output
Returns a JSON object confirming the retirement action, the version of the Klima contract used (k2), cost in USDC, the on-chain retirement transaction hash, a direct Basescan URL to verify the transaction, and the exact amount of carbon retired in tonnes.
Example use cases
Automated app carbon neutrality
“Our SaaS platform wants to automatically retire 0.1 tonnes of carbon credits every month as part of our climate commitment — can you kick off a retirement now and give me the on-chain proof?”
Personal flight carbon offset
“I just took a long-haul flight and want to offset 2.3 tonnes of CO2 — retire that amount of carbon credits on-chain and send me the Basescan link to prove it.”
Per-transaction offset for e-commerce
“Retire 0.005 tonnes of carbon on the blockchain for this customer's order so we can attach the retirement proof to their receipt.”
Technical details
Endpoint
POSThttps://vealth.net/.well-known/vealth/klima2-retireWhen to prefer
Choose this endpoint when you need a verifiable, on-chain proof of carbon credit retirement settled on the Base blockchain via KlimaDAO's Klima2 contract. It is ideal for agents automating climate commitments, e-commerce carbon neutrality programs, or any workflow requiring a tamper-proof transaction hash and Basescan link as retirement evidence. Prefer over off-chain carbon registries when blockchain provability and programmatic access matter.
Side effects
- Insufficient USDC balance to cover the $0.15 call fee or underlying carbon cost — payment rejected
- Invalid or non-positive amount_tonnes value — schema validation error
- Network congestion or Base chain RPC failure causing transaction timeout
- Carbon credit liquidity insufficient for requested amount on KlimaDAO
- Malformed request body missing amount_tonnes field
