2 endpoints for currency listings: digital cryptocurrencies and fiat currencies supported by Binance C2C. Both use headers-only authentication — no HMAC signature required.
Headers-Only Authentication
Unlike most SAPI endpoints, EP-39 and EP-40 only require the clientType: web header. No X-MBX-APIKEY, no timestamp, no HMAC signature.
# Both currency list endpoints:
curl -X POST "https://api.binance.com/sapi/v1/c2c/digitalCurrency/list" \
-H "clientType: web" \
-d '{}'
# No API key or signature needed
