Buy USDT/BTC/ETH with Cameroon MoMo

POST/crypto/sell

Sell crypto to MoMo cash-out

GET/crypto/portfolio

Vault and XAF balances

POST/crypto/withdraw

Send USDT, BTC, or ETH on-chain

curl -X POST "https://api.gryllex.com/api/v1/crypto/buy" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"fiatAmount":5000,"asset":"USDT","network":"MTN","msisdn":"670000000"}'

Session JWT

Authenticate as a user and pass Authorization: Bearer on each request. User-issued API keys are not available yet.

Inbound webhooks

Settlement events land on Gryllex from our rails and bill providers. Outbound webhooks to your app are not live.
