From the listing.

POST https://app.fortiblox.com/api/quote
content-type: application/json

{
  "amountIn": "1000000",
  "inputMint": "B69chRzqzDCmdB5WYB8NRu5Yv5ZA95ABiZcdzCgGm9Tq",

}

Parameters

Parameter	Type	Required	Description
`amountIn`	string	No	raw base units of inputMint (exactIn)
`amountOut`	string	No	raw base units of outputMint (exactOut — GROSS target)
`inputMint`	string	Yes	base58 X1 mint address
`maxHops`	number	No	default 4; clamped to 1-8 by the pathfinder. Keep ≤ 6 so /api/tx/build (on-chain router, max 6 legs) executes the same route.
`mode`	string	No	default exactIn. exactOut is served as a reverse-quoted exact-in: amountIn = the required input (spent exactly; maxAmountIn echoes it), amountOut/amountOutNet/minimumAmountOut are the forward quote at that input, requestedAmountOut is your target One of: exactIn, exactOut.
`outputMint`	string	Yes	base58 X1 mint address
`payer`	string	No	base58 payer for simulate:true
`simulate`	boolean	No	simulate the build (needs payer)
`slippageBps`	number	No	explicit slippage in bps (clamped); omitted = dynamic
