How this service works
Exit analysis: sell $N of a token and see what you actually receive, the slippage, and the largest position that exits under 5%. Constant-product maths on live pool reserves, not a safety grade.
Output
Returns the actual USDC (or quote token) proceeds from selling $N of the token, the realized slippage percentage, and the maximum position size that exits with less than 5% slippage — all computed from live on-chain pool reserves using constant-product AMM math.
Example use cases
Pre-exit slippage check for large holder
“I'm holding a big bag of the token at mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — if I sell $5000 worth, how much will I actually receive and what's my slippage?”
Finding max safe exit size
“What's the largest amount of the token at mint So11111111111111111111111111111111111111112 I can sell and still keep slippage under 5%?”
Comparing exit impact across tokens
“Before I dump my position, can you check the exit slippage and real proceeds for selling $250 of the token with mint mSoLzYCxHdYgdzU16g5QSh3i5K3z3KZK7ytfqcJm7So?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/exit-check/:mint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise, live AMM-computed exit analysis for a specific token on Arc — particularly when evaluating whether a large position can be sold without excessive slippage. Prefer this over generic price APIs when the question is 'what will I actually receive?' rather than 'what is the mid-market price?' It is specifically tuned for constant-product pool math on Arc (Uniswap v4) and gives you the maximum safe exit size under 5% slippage, which generic oracles do not provide.
Side effects
- Invalid or unknown mint address returns an error — ensure the mint is a valid token on Arc
- No pool found for the mint — token may not have a Uniswap v4 pool on Arc
- Sell amount too large relative to pool liquidity — result may show extreme slippage or rejection
- Pool reserves unavailable or stale — live data fetch may fail if RPC is degraded
- Missing mint parameter in URL path returns a 400-level error
