How it works
One id, one feeRequest shape
Send a GET to /api/v2/fees/blockchain/{id} where id is a numeric currency id or token id.
- Native/fees/blockchain/1BTC fee
- Token/fees/blockchain/4:0xdac17f958d2ee523…USDT-ERC20
The response is a single decimal number representing the fee in the currency's smallest unit.
Fees move with the network
Quoted fees reflect the chain's current gas/congestion. Cache sparingly — for high-value sends, re-fetch right before submitting the spend request so your buffer stays accurate.
