# Quick start

The Lune API makes it very easy to purchase carbon offsets:

  1. Sign up (opens new window) to Lune
  2. Validate your email
  3. Get your API Key (opens new window) from the dashboard

then:

curl https://api.lune.co/v1/orders/by-mass \
  -H 'Authorization: Bearer <API_KEY>' \
  -H 'Content-Type: application/json' \
  -X POST \
  -d '{"mass": { "amount": "100.510", "unit": "t"} }'

You've just purchased 100.51 tonnes of Carbon Offsets! 🎉
