# List Threads

`GET /v0/threads`

Lists threads, most recent first. Pass `senders`, `recipients`, or
`subject` to filter by substring. Filtered requests are served by
search, which caps `limit` at 100. For relevance-ranked full-text
search across senders, recipients, subject, and message body, use
`Search Threads`.

**CLI:**
```bash
agentmail threads list
```
