exit_check
may change things: you confirm before it runsSEVEN CHAINS, FROM LIVE RESERVES OR AN AGGREGATOR QUOTE (for an executed sell test use arc_exit_check on Arc or base_exit_check on Base). Before you buy a token, find out whether you can sell it. Give a token address and a position size in USD and this returns what you would actually receive, the slippage, and the largest position that exits under 5%. WORKS ON SEVEN CHAINS: Solana and X1 (base58 address, constant-product maths against the pool's live reserves and its own fee) and five EVM chains (0x address, routed through LI.FI to USDC) - Base 8453 (the default), Ethereum 1, Arbitrum 42161, Optimism 10, Polygon 137. Any other chain id returns UNSUPPORTED_CHAIN and names these five; it is never reported as a token you cannot sell. This is deliberately NOT a safety grade. Safety grades describe the contract (mint authority, LP burn, holder count); exitability describes the depth. A token can score 100 on every safety check and still be untradeable — PROOF does exactly that in our own data. Verdicts on Solana/X1: EXITABLE, PARTIAL, COSTLY, TRAPPED, THIN, NO_POOL, UNPRICED. On EVM: EXITABLE, PARTIAL, COSTLY, THIN, NO_ROUTE, UNKNOWN. NO_ROUTE means the aggregator we check found no way out, which is strong evidence and not proof that no venue anywhere will take it; UNPRICED and UNKNOWN mean we could not resolve a value and are NOT judgements about the token. PAID: $0.004 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1; no key, no sign-up) at https://apexfaucet.xyz/api/x402/exit-check/{mint}?usd=<usd>&chain=<chain id>. Over MCP this tool answers with that price and URL, not the data.
