Rate Limits for Models API

The Models API has a single rate limit for all requests except for requests made via Apex methods in sandbox, demo, and trial orgs. When calling the Models API through Apex in a sandbox, demo, or trial org there are different limits. This document covers the rate limits for REST endpoints and Apex methods, sandbox orgs, and demo and trial orgs.

The following limit applies to all Apex and REST requests in regular production orgs.

The Models API is limited to 70 requests per minute per org for each REST endpoint (or equivalent Apex method).

If a rate limit is exceeded, the Models API returns a response with a 429 status and an error object.

To request a rate limit increase, reach out to your Salesforce account executive.

The Apex methods of the Models API are also subject to the Apex Callout Limits and Limitations.

All Models API requests are subject to Salesforce’s usage and billing rates. See Einstein Usage.
