<Update label="April 28, 2026">
  ### New

  * **Crawler chaining** — a squid can now automatically feed its results into a second crawler as soon as a run completes. Configure a chain on any squid by setting a `chain` object with the following fields:

    | Field              | Type    | Description                                                                                                                                     |
    | ------------------ | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
    | `target_crawler`   | string  | Slug of the crawler that will receive the results as inputs                                                                                     |
    | `field_map`        | object  | Maps a result field from the source to an input param on the target (e.g. `{"url": "url"}`)                                                     |
    | `autostart`        | boolean | If `true`, the downstream run starts immediately. If `false`, tasks are queued and the run is left paused for manual review. Defaults to `true` |
    | `cluster_settings` | object  | Optional — pre-configure the downstream squid's `name` and `concurrency` on first creation                                                      |

  * **`GET /v1/squids/{id}`** — response now includes a `chain` object when a chain is configured on the squid

  * **`GET /v1/runs`** — runs triggered by a chain now include `"origin": "chain"` in the response
