An API key now grants access to your company’s billing data. Any holder of the key can read your current credit balance, your consumption breakdown, your subscription contract (plan, status, active features and effective limits), and your credit ledger history.
Billing endpoints are authenticated with the sameX-Api-Key header as every other endpoint. There is no separate credential and no second scope for billing: whoever can call GET /Campaign can also call GET /Consumption, GET /Consumption/breakdown, GET /Subscription and GET /Consumption/transactions.If you distributed an API key before billing was placed behind it — for example to an integration partner, a script, or a third-party service — that key now exposes financial information it did not expose at the time you shared it. We recommend you audit and review where your keys are used, and rotate any key whose exposure is broader than you are comfortable with.
No pricing details (rates, discounts, Stripe identifiers) are ever exposed through the API. What a key can read is your consumption, your remaining balance, and the terms of your contract — see the Track Consumption guide.
You’re all set! Head over to the API Reference to explore the available endpoints.
