# Price Calculation

All selections in Fixed Exotics markets have **“price”: 0**.\
In order to fetch the price for the selection a player made, you are required to make a request to the Fixed Exotics price API endpoint.

[Fixed Exotics API](/odds88-client-api/odds88-api-endpoints/fixed-exotics-api.md)
{% endcontent-ref %}

Request body must contain **eventId**, **marketId** and **racingSelection** like in the following example:

```javascript
{
  "eventId": 4183647,
  "marketId": 22369909,
  "racingSelection": "EXACTA 1/8"
}
```

**racingSelection** should contain the name of the market (**EXACTA**, **QUINELLA** or **TRIFECTA**), followed by the selection itself. In Quinella, selections are separated by dot **(.)** and the order of selections is not important ( **QUINELLA 1.8 = QUINELLA 8.1** ). In exacta and trifecta, selections are separated by **(/)** and the order of selections is important ( **EXACTA 1/8 != EXACTA 8/1** ), different orders will result in different prices for these markets.

Response for this request is the price for the specified selection:

```javascript
{
  "rejectReason": 0,
  "message": "Checks passed",
  "odds": 51
}
```

Possible rejection reasons can be checked via the corresponding dictionary endpoint.
