Miso Rate Limits

MISO publishes rate limits on exactly one of its two public data surfaces. The keyed MISO Data Exchange gateway (apim.misoenergy.org) enforces a hard, numeric, per-subscription rate limit and daily quota that MISO states in its own Data Exchange FAQ. The anonymous Public API (public-api.misoenergy.org) carries no enforced, documented limit at all — MISO instead publishes a politeness request on the RT Data APIs page asking callers not to poll faster than once per minute. Both are recorded here verbatim; the second is guidance, not an enforced limit, and is marked as such.

Miso Rate Limits is the machine-readable rate-limit profile for MISO on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring requests_per_minute and requests_per_day.

The profile also includes response codes documented for throttled and quotaExceeded.

Tagged areas include Rate Limiting, Energy, and Open Data.
