Endpoint should return all available tokens that you support.
Either as pairs or as a list, depending on your implementation (is every combination supported as long as both tokens are supported?)
Tokens should be represented as a combination of chainId and address.
Get a quote for a token pair and an specified amount. The below example is from another dex integration we have built, details can be discussed.
Request params:
{
"chainId": required, the chain's id, default Ethereum's chain id,
"fromTokenAddress": required, the address of the source token for the swap,
"toTokenAddress": required, the address of the destination token for the swap,
"fromAmount": required, the swap amount adjusted for the token's decimal places,
"toAddress": required, the recipient of the target token,
"slippage": optional, default 0.005
}Request example:
{
"chainId": 1,
