Quoting

The quote endpoint ranks swap routes across all major Solana DEXes using local math, without on-chain simulation for cached pools.

How It Works

1. Venum maintains live pool state via streaming
2. When you request a quote, it computes the output amount locally for each known pool
3. Pools are ranked by output amount — best route first
4. Cached pools can often be quoted without extra RPC round-trips

Request

POST /v1/quote

{
  "inputMint": "So11111111111111111111111111111111111111112",
  "outputMint": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
  "amount": "1000000000",
  "slippageBps": 100
}

Field	Type	Required	Description
inputMint	string	Yes	Base58 token mint address or tracked token symbol
outputMint	string	Yes	Base58 token mint address or tracked token symbol
amount	string	Yes	Amount in smallest units (lamports for SOL)
slippageBps	number	No	Slippage tolerance in basis points (default: 100 = 1%)

Response

Returns up to 5 routes, sorted by output amount descending:

{
  "routes": [
    {
      "dex": "orca-whirlpool",
      "poolAddress": "HJPjoWUr...",
      "outputAmount": "134520000",
      "priceImpactBps": 1,
      "feeBps": 4
    }
  ],
  "bestRoute": { ... },
  "poolsScanned": 7
}

Quoting Math

Venum uses different math per DEX type:

DEX Type	Method
Constant product (Raydium AMM, PumpSwap, Orca Token Swap)	output = (amountIn * reserveOut * (10000 - feeBps)) / (reserveIn * 10000 + amountIn * (10000 - feeBps))
Concentrated liquidity (Orca Whirlpool, Raydium CLMM)	sqrtPrice-based approximation within current tick range
Meteora DLMM	price = (1 + binStep/10000) ^ activeId
Saber StableSwap	Newton's method on stable curve

All math runs in-process using cached pool state, which can reduce RPC round-trips.
