Policies

Documentation Status

Ameren does not publish public per-second or per-minute API rate limits. Throughput, concurrency, and burst behavior are governed by the relevant partner, supplier, or merchant agreement.

Backoff Strategy

Where any HTTP API is exposed, clients should implement exponential backoff with jitter and honor any Retry-After header returned on 429 or 503 responses.
