# Rate Limits

> Default rate limits for Exa API endpoints

</Info>

Our API endpoints have default rate limits to ensure reliable performance for all users. Most endpoints are limited by QPS. The legacy Research API (`/research/v1`) uses concurrent task limits for its long-running operations.

| Endpoint                           | Limit               |
| ---------------------------------- | ------------------- |
| `/search`                          | 10 QPS\*            |
| `/contents`                        | 100 QPS             |
| `/answer`                          | 10 QPS              |
| `/research/v1` (legacy/deprecated) | 15 concurrent tasks |
