# Entity Credit Operations

> Paginate immutable Entity-attributed credit history

**Auth:** secret key only. When API permissions are enabled, the key requires `entity:read`. Publishable keys are rejected.

Query parameters:

* `credit_system_code` — optional exact system filter;
* `limit` — 1 to 100, default 50;
* `cursor` — opaque cursor from `next_cursor`, maximum 512 bytes.

```http theme={null}
GET /customers/workspace_123/entities/user_42/credit-operations?credit_system_code=ai_credits&limit=50
Authorization: Bearer sk_nozle_...
```

The response includes grants, transfers, consumes, denials, expiry, revocation, refunds, and adjustments attributed to that exact Entity UUID. Each operation preserves exact decimal amounts, metric/rate snapshots, status, occurrence time, and source allocations.

`next_cursor` is JSON `null` at exhaustion. Pass a non-null cursor back unchanged; do not construct or decode it.
