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.
Example use cases
Memecoin exit impact check
“I'm holding a Solana memecoin at address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU and want to sell $2000 worth — how much will I actually get after slippage, and is there a safer smaller size I could exit under 5% price impact?”
Large position liquidity sanity check
“Before I exit my $10,000 position in the token at Solana address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, can you run the exit math and tell me the actual receive amount, the slippage, and what the biggest sell is that stays under 5% impact?”
Comparing slippage across sell sizes
“I'm trying to figure out the best size to sell for the Solana token at address So11111111111111111111111111111111111111112 — simulate a $500 sell and show me the slippage and max low-impact exit size based on current pool reserves.”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/exit-check/:solana_address?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
