How this service works

Slippage Sentinel analysis

Output

Returns a JSON object with ok status, pool depth breakdown per AMM (USD value, in/out amounts, AMM key), diagnostics (input USD value, stress multiplier, volatility buffer bps, worst observed price impact bps, trade sample count and window), minimum safe slippage in basis points (minSafeSlipBps), 95th-percentile recent trade size stats, and candidate slippage evaluations for the requested trade.

Example use cases

Large token swap safety check

“I'm about to swap 500k USDC for SOL on Jupiter. What's a safe slippage setting so I don't get hammered by price impact?”

Low-liquidity pool risk assessment

“Before I execute this trade on Pump.fun, can you check how deep the pool is and tell me what slippage cushion I need to protect against volatility?”

ExactOut trade execution planning

“I need to receive exactly 100 SOL. What slippage should I set on Raydium to make sure this ExactOut trade goes through safely without too much price impact?”

Technical details

Endpoint

POSThttps://x402.dexter.cash/api/slippage/sentinel?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a data-driven, per-trade slippage recommendation for Solana DEX swaps, especially for large trades where price impact matters. Prefer this over static slippage defaults when trading on volatile or low-liquidity pools, or when you need diagnostics like pool depth, volatility buffer, and worst observed impact to decide whether a swap is safe to execute.

Side effects

Invalid or unsupported DEX name — service may return ok:false or error
Unknown token mint address — quote context unavailable
Insufficient trade sample data — falls back to wider window or default slippage
Amount too small or too large for meaningful pool depth analysis
Payment not provided or invalid x402 payment — 402 Payment Required response

Schema · Request body

Field	Type	Description
mode	string	Swap direction passed to Jupiter (default ExactIn).
token_in	string	Input mint (defaults to SOL). Provide a 32-byte mint address.
amount_in	string	Optional atomic trade size. Overrides amount_in_ui when provided.
token_out	string	Output mint to analyze. Blank uses the Donica Lewinsky (DONICA) mint.
route_hint	string	Optional label for diagnostics grouping (defaults to diagnostics).
amount_in_ui	number	UI trade size (e.g. 10 for 10 SOL). Used when amount_in is omitted.
amount_in_decimals	integer	Token decimals for amount_in_ui. Required when amount_in_ui is used.
