# Convert Fiat to Crypto

`GET /v1/bridge/convert`

Convert fiat currency amount to cryptocurrency token amount. Supports multiple fiat currencies based on available price data for the specific token. Returns the equivalent amount of crypto tokens for the specified fiat amount based on current market prices. If price data is not available for the requested currency, the API will return a 404 error.

**Native Tokens**: To get the price of native tokens (like ETH on Ethereum), use the address `0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE`. For example, to get the price of ETH on Ethereum Mainnet (chainId: 1), pass `to=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE`.

**Authentication**: Pass `x-client-id` header for frontend usage from allowlisted origins or `x-secret-key` for backend usage.
