# ApexFaucet Exit Check — Solana Token Sell Impact Estimator

> ApexFaucet Exit Check — Solana Token Sell Impact Estimator is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).

Simulates selling a given USD amount of a Solana token using constant-product AMM math on live pool reserves, returning the actual received amount, slippage, and the largest position that exits under 5% price impact.

## 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-exit-check-solana-token-sell-impact-estimator-dc1c9b19
```

Example prompt: How much would I actually receive if I sold $1000 of the token at Solana address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU, and what's the slippage? Also tell me the largest position I could exit under 5% price impact.

## When to prefer this

Use this endpoint when you need realistic, math-based exit simulation for a Solana token using actual on-chain pool reserves rather than quoted estimates. It is specifically suited for constant-product AMM (e.g. Uniswap-style) pools on Solana/X1 and provides the critical '5% max exit size' metric that traders need before executing large sells. Prefer this over generic price APIs when you need slippage-aware exit planning, not just a spot price.

## Known failure modes

- Invalid or unrecognized Solana token address returns an error or empty pool data
- Token has no indexed liquidity pool, resulting in inability to compute reserves
- Extremely low-liquidity pools may return extreme slippage figures that are technically correct but practically unusable
- Stale pool data if reserves haven't been indexed recently
- Missing sell amount parameter causes request failure

## 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 simulated received token or USDC amount after the sell, the percentage slippage incurred, and the largest position size (in USD) that can be exited while keeping price impact under 5%, all derived from live constant-product AMM pool reserve data.
