The API Usage page shows how your account uses the Opensolr API: how many calls, to which endpoints, and how close you are to your limits.
01 · What the page shows
Every call of your account in the month you pick.
AI requests used against your monthly allowance: API Quota.
Your calls right now, next to your limits.
Calls per endpoint, most used first.
Your calls in each of the last six months.
02 · How the limits count
Every call counts once, in the minute and in the hour it is made. The counters start again at each new minute and each new hour of the clock.
The per-minute limit counts your account and, separately, the address the calls come from.
Over a limit, the API answers 429 Too Many Requests with Retry-After: 60 (ERROR_RATE_LIMIT_PER_MINUTE) or Retry-After: 3600 (ERROR_RATE_LIMIT_PER_HOUR).
Reading your own Data Ingestion queue is never limited.
