# 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](/dtm-docs/dtm-api/response-format/error-responses.md) (too many requests) until the end of the rate-limiting period as defined in the response.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.getdor.com/dtm-docs/dtm-api/rate-limiting.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
