# Fast

Source: [Official documentation](<https://newlistings.pro/docs/v2/fast>)

New Listings Feed's `/v2/fast` stream sends raw announcement titles and X posts before parsing, with source URLs and event timestamps for clients running their own parser.

| Key | WebSocket URL |
| --- | --- |
| FREE | No access |
| STARTER, PRO | `wss://tokyo.newlistings.pro/v2/fast`, `wss://ny.newlistings.pro/v2/fast` or `wss://seoul.newlistings.pro/v2/fast` |

Filter the stream with `exchange`, `data_type` and `username` in the connection URL. See [Filters and coverage](<https://newlistings.pro/docs/v2/filter-values>).

## Event fields

| Field | Type | Notes |
| --- | --- | --- |
| `id` | integer | Opaque event ID for this edge and endpoint. |
| `type` | string | `announcement` or `tweet`. |
| `exchange` | string | Canonical exchange identifier. |
| `username` | string | Present only on `tweet` events. |
| `text` | string | Announcement title or post text. |
| `url` | string | Source URL. |
| `detected_time_us` | integer | Detection time as Unix epoch microseconds. |
| `sent_time_us` | integer | Publication time as Unix epoch microseconds, after any plan delay. |

Do not use `id` to join or deduplicate events across Fast, Full or regional edges. IDs are allocated independently. See [Measure delivery](<https://newlistings.pro/docs/v2/measure-delivery>) before interpreting the timestamps.
