# Rate Limits

> API rate limits and how to handle them.

## Default limits

| Plan      | Requests per minute | Concurrent requests |
| --------- | ------------------- | ------------------- |
| Free tier | 60                  | 10                  |

Rate limits are applied per API key. If you need higher limits, contact us.

## Rate limit headers

When you approach or exceed limits, responses include:

| Header                  | Description                           |
| ----------------------- | ------------------------------------- |
| `X-RateLimit-Limit`     | Maximum requests per minute           |
| `X-RateLimit-Remaining` | Remaining requests in current window  |
| `X-RateLimit-Reset`     | Unix timestamp when the window resets |

## Handling rate limits

When rate limited, you'll receive a `429` status code:

```json theme={null}
{
  "error": {
    "message": "Rate limit exceeded",
    "type": "rate_limit_error"
  }
}
```

### Recommended retry strategy

```python theme={null}
import time
from openai import OpenAI, RateLimitError

client = OpenAI(
    base_url="https://www.opencompress.ai/api/v1",
    api_key="sk-occ-your-key-here",
)

def call_with_retry(messages, max_retries=3):
    for attempt in range(max_retries):
        try:
            return client.chat.completions.create(
                model="gpt-4o-mini",
                messages=messages,
            )
        except RateLimitError:
            wait = 2 ** attempt  # exponential backoff
            time.sleep(wait)
    raise Exception("Max retries exceeded")
```

<Tip>
  The OpenAI SDK has built-in retry logic. By default, it retries rate-limited requests with exponential backoff.
