# Get fan insights in bulk (POST batch)

`POST /insights/fans/batch`

Returns detailed insights for up to 100 fans in a single request, keyed by the input fan UUID.

This is the high-cap, JSON-body counterpart to `GET /insights/fans` (capped at 20 via query string). It is intended for initial-sync flows that need to hydrate many fans without per-fan round trips.

Per-key errors are reported inside the 200 response body so a single forbidden or missing fan never collapses the whole request — consumers can keep partial results and only retry the failing keys.

Every field carries the same meaning as on `GET /insights/fans/{userUuid}`, including which money fields are net of reversals and which are gross, and the same absence of caching.

<Note>Maximum 100 fan UUIDs per request. Failed keys are reported as `{ "error": "forbidden" | "not_found" | "internal" }`.</Note>

## Headers

- `X-Fanvue-API-Version` string, required

## Request body

- object
  - `userUuids` string[], required — Array of fan UUIDs to fetch insights for (1-100)

## Response `200`

Per-key insights or error for each requested fan. Always 200 when the request itself is valid, even if every key fails.

- object — Map of input fan UUID to insights or a per-key error (forbidden, not_found, or internal).
