# Rate Limiting

To ensure that our API remains stable and performant, the DTM API is rate-limited.

While most implementations are likely never to hit a rate limit, developers are expected to use techniques such as caching results, limiting requests, and implementing exponential backoffs to limit load on the API.

When a rate limit is triggered, all subsequent requests will receive a [429 HTTP response](https://docs.getdor.com/dtm-docs/dtm-api/response-format/error-responses) (too many requests) until the end of the rate-limiting period as defined in the response.
