# Rate limits and complete exports

Per-user limits for each endpoint and how to export a full date range.

## Default limits

Default application rate limits per user

| Endpoint | Limit | Shared budget |
| --- | --- | --- |
| [Session list](https://www.trellus.ai/developers/api/list-calls) | 2 requests per 4 seconds | Shared by v5 and v6. Pace calls at least 2.5 seconds apart. |
| [Metric details](https://www.trellus.ai/developers/api/metrics) | 4 requests per 4 seconds | Shared by v6 and v7. |
| [Session detail](https://www.trellus.ai/developers/api/session) | 1 request per second |  |
| [Visible directory](https://www.trellus.ai/developers/api/visible) | 2 requests per 4 seconds |  |
| [Bootstrap](https://www.trellus.ai/developers/api/bootstrap) | 2 requests per 4 seconds |  |

## Complete exports

- Session-list returns the newest matching rows, sorted by started_at descending. There is no cursor or offset.
- Use a maximum limit of 1000. If a time window reaches the cap, divide it into smaller [start, end) windows and deduplicate by session_id. Dense windows may also require rep filters. Do not label a capped or sampled response as a complete export.
- Default limits apply per user; coordinate workers sharing a key. Account overrides and upstream protection may differ.
- On 429, wait the Retry-After delay in seconds. Use bounded backoff for transient 5xx responses and read errors as text.

A response containing 1,000 rows may have reached the cap. It does not establish that you received every matching call. Use aggregates for totals and clearly label capped or sampled lists.
