Usage and limits

For Headless APIs, the usage is based on MAUs (Monthly Active Users). MAU is the number of unique users (with uniqueness defined by the user-ID) that create or consume content on Circle servers through SDK or API within a monthly billing cycle. All service requests except authentication* are counted as MAU. MAU number is based on per-user instead of per-device, meaning that a user with the same user-ID with multiple devices will be counted as 1 MAU.

Exceptions

Authentication endpoints are not taken into account, so you can use them without increasing your MAU count. Here's a list of what we consider Auth endpoints:

• /api/v1/headless/access_token/refresh

• /api/v1/headless/access_token/revoke

• /api/v1/headless/auth_token

• /api/v1/headless/refresh_token/revoke

• /api/headless/v1/cookies

• /session/cookies (cookies redirect URL)
