Centerpoint Energy Rate Limits

Upgrades the 2026-05-04 bulk-sweep generated file, which asserted that no numeric limit was visible without registration. One published numeric limit does exist and is stated in the open Smart Meter Texas 3.0 Data Access Interface Guide (fetched HTTP 200, 2026-09-05): On-Demand Reads are capped at 3,000 per day per Transmission and Distribution Utility. That cap is shared across every caller reading meters on CenterPoint Energy Houston Electric's network, not allocated per API credential — an integrator competes for it with every other authorized third party on the same TDU. No other function publishes a numeric ceiling, and the guide documents no rate-limit response headers at all.

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

It captures 3 rate-limit definitions, measuring on-demand meter reads and requests.

The profile also includes 3 backoff/retry policies defined.

Tagged areas include Energy, Utility, Smart Meter, Green Button, and Rate Limiting.

Policies

Customer authorization bounds volume
Calls operate only against ESI IDs covered by an executed Energy Data Sharing Agreement; the agreement's scope and duration constrain usable request volume more than any published throttle.
Asynchronous bulk retrieval
Bulk requests return a correlation identifier and are collected via Report Status rather than served synchronously, which is the platform's actual load-shedding mechanism in place of a request throttle.
Backoff on 500
The guide's only failure-retry guidance is the 500 message "Something went wrong. Please try again later."; exponential backoff with jitter is the caller's responsibility and is not specified.
