## cohorts/create

`GET /v1/cohorts/create`

Save a set of up to 100 accounts, subreddits or handles as a cohort you can sweep with one keyword.

*Create a cohort*

| Parameter | Required | Description |
| --- | --- | --- |
| `name` | yes | Human label for this cohort (max 200 characters) — e.g. `Rust ecosystem` |
| `members` | yes | The accounts to sweep: a comma-separated platform:identifier list, or a JSON array of {"platform","identifier"} objects. 1-100 members; every platform must exist in the catalogue. — e.g. `reddit:rust,hackernews:steveklabnik,github:rust-lang/rust,bluesky:rust-lang.bsky.social` |
| `dry_run` | no | Read a zero-credit estimate without fetching sources, running AI, or reserving credits. Cache status is a snapshot, not a guarantee at execution. — e.g. `1` |

**Cost:** 1 credit at list price per successful uncached response; variable-cost operations may quote or settle a different charge. Confirmed uncharged or refunded failures report zero. Pending reconciliation can report credits_used:null; retain request_id and the original idempotency key.
