Mattermark Rate Limits

Mattermark enforces a per-account request quota rather than a per-second rate. Every response on both the REST and GraphQL surfaces carries three quota headers, and a dedicated usage endpoint reports current standing without consuming quota. Exceeding the quota returns HTTP 429. The absolute quota number is account/plan dependent and is not published as a plan attribute; the documentation's worked example shows a 10,000-request period, which is recorded below as an example value, not as a committed tier limit.
