# Getting Started

Make your first Market Data API request, then use the API Reference to explore the available data domains.

## 1. Create an API key

Register or sign in at the [SoSoValue Developer Dashboard](https://sosovalue.com/developer/dashboard), select **Apply your Key**, and submit the requested application details. The approved key is available from the same dashboard.

Keep the key in a secret manager or environment variable. Do not commit it to source control or expose it in client-side code.

## 2. Choose the API host

All Market Data API endpoints use this base URL:

```
https://openapi.sosovalue.com/openapi/v1
```

Endpoint paths in the API Reference are relative to this URL.

## 3. Make your first request

Include the API key in the `x-soso-api-key` request header. This example returns the supported currency list:

```bash
curl "https://openapi.sosovalue.com/openapi/v1/currencies" \
  -H "Accept: application/json" \
  -H "x-soso-api-key: YOUR_API_KEY"
```

See [Currency List](/documentation/for-developers/api-reference/market-data-api/currency/list.md) for the response fields.

## 4. Continue your integration

Review the shared identifiers, timestamps, pagination, and time-window conventions before implementing additional requests.
