Request quotas

Know what each call costs

Every data request is one request against two allowances: per month and per minute. Nothing is metered by row or by endpoint, so the cost of a polling loop is simply how often it polls.

Budget a polling loop

  • Polling /api/v1/changes every 15 seconds is 4 a minute and about 172,800 a month, inside Scale: a job for the stream instead, which counts once per connection.
  • Reading one league's board every 5 minutes is about 8,640 a month, inside Developer.
  • Page with the largest limit an endpoint allows: 200 rows in one request costs the same as 5.
