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, 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:

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

See Currency List for the response fields.

4. Continue your integration

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