Composio enforces rate limits **per organization** over a fixed one-minute window. Every authenticated endpoint draws from the same budget — tool execution, connected accounts, triggers, and the rest — so the limit below is your organization's total across all API calls.
|
|
|
|
## Rate limits by plan
|
|
|
|
| Plan | Rate limit | Window |
|
|
|------|------------|--------|
|
|
| Starter | 2,000 requests | 1 minute |
|
|
| Hobby | 2,000 requests | 1 minute |
|
|
| Growth | 10,000 requests | 1 minute |
|
|
| Enterprise | Custom | - |

## Rate limit headers
|
|
|
|
Every response includes headers so you can track usage without guessing:
|
|
|
|
| Header | Description |
|
|
|--------|-------------|
|
|
| `X-RateLimit` | Total requests allowed in the current window |
|
|
| `X-RateLimit-Remaining` | Requests remaining in the current window |
|
|
| `X-RateLimit-Window-Size` | Window size (e.g., `60s` for 60 seconds) |
|
|
| `Retry-After` | Seconds until the window resets (only on 429 responses) |
|
|
|
|
## Rate limit response
|
|
|
|
When you exceed the rate limit, you'll receive a `429 Too Many Requests` response:
|
|
|
|
```json
|
|
{
|
|
"message": "Rate limit exceeded. Limit: 10000 requests per 1 minutes"
|
|
}
|
|
```
|
|
|
|
## Best practices
|
|
|
|
1. **Watch `X-RateLimit-Remaining`** — read it on each response to know how much headroom you have left in the window.
|
|
|
|
2. **Honor `Retry-After`** — on a `429`, wait the number of seconds it gives you before retrying instead of hammering the endpoint.
|
|
|
|
3. **Cache what doesn't change** — keep tool definitions and other static data client-side so you don't spend requests re-fetching them.
|
|
|
|
## Need higher limits?
|
|
|
|
If you hit these limits regularly, upgrade your plan or [talk to us](https://calendly.com/composiohq/enterprise) about custom limits for your use case.
