# Rate limits

How many requests a key may make, and what to do when you hit the limit.


Each API key may make **120 requests per minute** by default, counted separately for reading, writing, media, and short links. You can set a lower limit when you create a key.

When you go over, the API answers `429 Too Many Requests` with a `Retry-After` header (seconds). Wait that long, then retry.

Other limits worth knowing:

| Limit | Value |
|---|---|
| API keys per account | 10 |
| Webhook endpoints per account | 5 |
| Short links per account | 500 active |
| Page size for lists | up to 100 |
| Scheduled posts per month | set by your plan (see `GET /usage`) |
| Media by URL import | 25 MB (use the upload flow for larger files) |
| Images / videos in the library | 50 MB / 500 MB per file, plus your plan's storage |

Posts also follow each platform's own limits, such as 280 characters on X. See [platforms](/docs/platforms).
