ERCOT Public Data API

Coverage is the ERCOT market in Texas, with product frequencies ranging from sub-hourly or hourly reports to daily and longer-period publications. API data begins at each product's Public Data API activation date; older historical files are retained for at least seven years. Access is limited to 30 requests per minute and 1,000 historic files per download, and regions outside the United States are currently restricted.

// Terms and limits

Access: free account, subscription key and API token
Free tier: A registered user can subscribe for a key and request an ID token valid for one hour. Historic-file downloads are capped at 1,000 files at once; the Data Access Portal permits the same report to be downloaded no more than three times in 12 months, after which stored copies should be reused.
Rate limits: 30 requests per minute; approximately one request every two seconds
Licence: Provider termsterms
Licence note: The API terms allow programmatic access through the documented means but provide the API and information "As Is" and let ERCOT set and enforce limits. Bot-created accounts are prohibited; users must not evade limits, and exceeding Data Access Portal limits requires ERCOT's written consent and may incur charges.
Attribution: No attribution requirement recorded.
