# Rate Limits

Octen enforces rate limits to ensure platform stability and fair usage across all customers.
Rate limits define how frequently you can call the API within a given time window. Requests that exceed these limits will be temporarily rejected.

## Broad Search, Web Search, Embedding & VL Embedding

The following QPS (Queries Per Second) limits are shared across the Broad Search, Web Search, Embedding & VL Embedding:

| Subscription | QPS Limit |
| :----------- | :-------- |
| Free         | 10        |
| Base         | 20        |

### How rate limits are applied

Rate limits are determined by your account plan and optional per-key caps:

* Each account has a default rate limit based on its subscription tier.
* When creating an API key, you may configure an additional rate limit for that key.
* If both are configured, requests are throttled by whichever limit is lower.

## Extract

The **Extract API** uses a rate limiting model based on requests per minute (RPM):

| Metric | Limit |
| :----- | :---- |
| RPM    | 100   |

## Model

The **Model APIs** are rate limited by requests per minute (RPM) and tokens per minute (TPM). Each model's usage is counted separately:

| Metric | Limit     |
| :----- | :-------- |
| RPM    | 300       |
| TPM    | 2,000,000 |

## Deep Research

Only a single concurrent request is supported.

## What happens when you exceed a limit

If a request exceeds the allowed rate:

* The request is rejected with a rate limit error.
* HTTP status: `429`

## Recommended retry behavior

When receiving a rate limit error:

* Check the `msg` for detail.
* Avoid immediate retries in a tight loop.
* Resume requests after the rate limit window resets.
* For high-throughput or bursty workloads, batching requests where supported can help reduce pressure on rate limits.

## Increasing rate limits

If your application requires higher throughput or sustained traffic:

* Custom limits or enterprise plans may be available.
* Contact the Octen team to discuss your use case.
