(To be released 12/12/2025)Updates to Rate Limits: We are updating how List endpoints are rate-limited. These updates allow us to provide improved reliability and performance on search activity both in the UI and API, while providing more throughput for core write and read operations.

We are introducing a new 20 requests per second rate limit across all List endpoints in Production, and a 5 requests per second rate limit across all List endpoints in Sandbox. The default 100 requests per second limit in Production, and 25 requests per second limit in Sandbox remains for all non-List endpoints.

• Current Rate Limits:
  • Production: 100 requests per second universal rate limit across all endpoints and API keys.
  • Sandbox: 25 requests per second universal rate limit across all endpoints and API keys.
• New Rate Limits:
  • Production:
    • 100 requests per second for rate limit across all non-List endpoints.
    • 20 requests per second rate limit across all List endpoints.
  • Sandbox:
    • 25 requests per second for rate limit across all non-List endpoints.
    • 5 requests per second rate limit across all List endpoints.

We have reviewed all customer API traffic patterns and have concluded that the new List endpoint rate limits will impact a very small subset of customers that will be able to utilize alternative patterns to power their integrations.

In the event that you do breach the new rate limit you will receive 429 errors in the same way that our standard rate limit operates.

We recommend building processes that consider our rate limits as upper bounds across your services. Please reference our rate limit documentation for recommendations on integrating to Modern Treasury with rate limits in mind.
