To keep the API fast and reliable for everyone, requests are rate limited per API key. These limits apply globally across all endpoints in Conductor’s API.

Budget by call, not by workflow step

When estimating your usage, count individual API calls—not the number of nodes in a workflow. A single node can generate many calls depending on the data you are querying. This matters most for asynchronous endpoints: polling an async query for its results will usually require several calls before the data is ready, and each poll counts against both your per-second and per-day limits.
When working with async endpoints, use a reasonable polling interval so you don’t exhaust your per-second limit while waiting for results. See Async Queries for the recommended pattern.
