# Delete a cohort

`DELETE /cohorts/{cohortId}`

## Request

- Base URL: `https://www.socialcrawl.dev/v1`
- URL: `https://www.socialcrawl.dev/v1/cohorts/{cohortId}`
- Auth: API key in header `x-api-key`

Deletes the cohort and cascades its members, queries, shards, and results. Active queries are marked cancelled. Immutable credit-ledger receipts are never deleted.

## Path parameters

- `cohortId` string, required

## Response `204`

Deleted. No response body.

## Other responses

- `400`: Invalid request - missing or malformed parameters
- `401`: Unauthorized - missing or invalid API key
- `404`: Not found - the endpoint does not exist, or the requested resource was not found upstream
- `405`: Method not allowed - wrong HTTP verb for this endpoint
- `409`: Conflict - an idempotent request is still in flight, its completed body exceeded the replay limit, or the cohort resource is not in a state that allows this operation
- `413`: Payload too large: the JSON request body exceeds the 1 MB size limit and is rejected before parsing, or a single cohort result cannot fit beneath the 1 MB response-page ceiling
- `422`: Idempotency payload mismatch - this Idempotency-Key was already used with a different request payload; or a discover request with async=false is over what one call can answer (NEEDS_ASYNC)
- `429`: Rate or concurrency limit exceeded. `RATE_LIMITED`: more than 600 requests in a 1-minute sliding window on this API key (headers `X-RateLimit-Limit`/`Remaining`/`Reset`; `Retry-After` is seconds until the window resets). `CONCURRENCY_LIMIT`: more than 50 simultaneous in-flight requests (headers `X-Concurrency-Limit`/`Remaining`; short static `Retry-After`). Both are unbilled. Honor `Retry-After`, then back off with jitter. See /docs/rate-limits.
- `500`: Internal server error - an immediate refund is attempted; credits_used reports the committed net charge and exact compensation is queued if that refund cannot commit
