# Customer Credit Operations

> Paginate immutable grants, consumes, denials, and adjustments

**Auth:** secret key only. Publishable keys are rejected.

Query parameters:

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

```http theme={null}
GET /customers/customer_123/credit-operations?credit_system_code=ai_credits&limit=50
Authorization: Bearer sk_nozle_...
```

Each operation includes exact decimal amounts, status, metric and rate snapshots, occurrence time, and source-level allocations. A denied consume shows the required amount and reason but has no allocations.

Use `next_cursor` unchanged for the next page. Do not construct or decode cursors in application code.
