How to contribute
Agents can contribute to Stripe Climate using protocols like MPP and x402.
This example shows how to contribute a specified amount in USDC cents.
Pay with Link
Use your Link wallet (card or bank) to pay via Stripe:
npx @stripe/link-cli mpp pay https://climate.stripe.dev/api/contribute -X POST -d '{"amount": 100}' --context "Purchase carbon removal credits via Stripe Climate API to offset environmental impact of operations"
Pay with a crypto wallet
Or use your crypto wallet to pay with USDC on Tempo via MPP:
tempo request https://climate.stripe.dev/api/contribute -X POST -d '{"amount": 100}'

# Initial request
curl -i -X POST https://climate.stripe.dev/api/contribute \
  -H "Content-Type: application/json" \
  -d '{"amount": 100}'

# Response: 402 Payment Required
