# apexfaucet.xyz Exit Check — Token Sell Slippage Analyzer

> apexfaucet.xyz Exit Check — Token Sell Slippage Analyzer is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-30).

Calculates the actual proceeds, slippage, and maximum exit size under 5% slippage for selling a given token amount, using constant-product AMM math on live pool reserves.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability apexfaucet-xyz-exit-check-token-sell-slippage-analyzer-106fd095
```

Example prompt: What will I actually get if I sell $1000 of the token at mint 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU, and what's the biggest amount I can exit with under 5% slippage?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
