# Read fee rates

> Returns success/message/data, with data.fee_rates and expiration.

<Note>Preview contract. Production availability remains subject to activation and release qualification. Examples are synthetic; the documentation cannot submit requests.</Note>

## Authorization

`read` on the authorized link, with no instrument restriction.

## Behavior

Returns success/message/data, with data.fee\_rates and expiration. Match fee\_schedule\_id to the selected catalog instrument and preserve decimal precision. A public exchange fee estimate is not a substitute for this account-specific view.

## Request example

```http theme={null}
GET /v1/fee-rates/list?exchange_link_id=17
Authorization: Bearer YOUR_API_KEY_FROM_PRIVATE_STORAGE
```

All IDs and dates are illustrative. URL-encode opaque query values and supply each allowed key once. Optional filters and their types appear in the generated schema below.

## Response and errors

The generated response schema below is the wire contract. Preserve fixed-point strings, nullable fields and endpoint-specific envelopes. Inspect HTTP status and Content-Type before decoding failures; reused trading routes may return JSON or plain text. Authentication, entitlement and exact link/instrument restrictions apply in addition to endpoint validation. See [errors and recovery](/api/errors-and-limits).

Read the [related guide](/api/accounts-and-instruments) for lifecycle, units and recovery semantics.
