/v1/slippage-map$0.005 per call · USDC over x402 · no account, no API key
Solana swap slippage / price-impact curve by trade SIZE: quotes the same pair at decade multiples of your base amount (via the Jupiter aggregator) and returns the impact per size plus a factual depth summary (largest tested size that stays under 1% / 5% impact). Execution intelligence beyond a single /v1/dex-quote. A quote, NOT an execution guarantee. NOT financial advice. Requires ?inputMint=&outputMint=&amount= (input base units).
inputMint (required) — Base58 mint you are selling, e.g. So11111111111111111111111111111111111111112 (SOL).outputMint (required) — Base58 mint you are buying, e.g. EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v (USDC).amount (required) — Base units of inputMint for the 1x reference size (lamports for SOL, 1e6 per USDC).slippageBps — Slippage tolerance in basis points for min-received, 0-5000 (default 50).mults — Optional comma-separated size multipliers of the base amount (default 0.1,1,10,100; up to 8).Call it → get HTTP 402 with USDC payment terms (Solana or Base) → pay with any x402 client → retry. Every paid answer ships an Ed25519-signed receipt you can verify offline. It reports unknown instead of guessing.
