<div class="section-label"><span class="num">03</span> Quota</div> <div class="section-title">Each prediction POST counts against your <em>plan</em>.</div> Your organization has a request quota. Each call to Grid, MaxFit, or PSR uses one unit. Several circumstance rows in one `theta` use one unit per row. Checking results or quota does not use a unit. If you are out of quota, the call fails with **429**. That is not a failed prediction. Wait, or ask CSA to raise the plan, then retry. Language clients expose `get_quota` / `getQuota`. You can also `GET /quota/summary`. A 429 is different from a body that is too large (413) and from a job that failed while running.
