How this service works
Coinlight charges USDC per API call with the x402 protocol on Solana and Base.
Output
A JSON response containing a top-level verdict of SELLABLE, RISKY, or UNSELLABLE, accompanied by an array of human-readable reasons. For Solana tokens, includes whether a sell route exists via Jupiter, the estimated round-trip loss percentage, price impact, and individual Token-2022 extension flags (transfer fee, transfer hook, permanent delegate, non-transferable, default-frozen) plus mint and freeze authority status. For Base tokens, includes honeypot flag, sell-tax percentage, blacklist flag, owner-control flag, and DEX liquidity data.
Example use cases
Meme coin rug-pull check before buying
“I'm about to buy this Solana meme coin at mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — can you do a full safety check and tell me if it's sellable, what the round-trip loss looks like on a $100 trade, and whether there are any Token-2022 traps I should know about?”
Base token honeypot detection for a trading bot
“Check if this Base ERC-20 token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed is a honeypot — I need to know if there are sell taxes, blacklist controls, or owner-control flags before my bot executes a buy.”
Pre-trade liquidity and exit check for a new launch
“There's a new token that just launched on Solana with mint address So11111111111111111111111111111111111111112 — before I put in $500, can you check whether I'd actually be able to exit the position and what the price impact would be on the sell side?”
Technical details
Endpoint
GEThttps://coinlight-app.vercel.app/p/token-sell-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a single, decisive pre-trade safety verdict before executing a buy on Solana or Base. It is uniquely valuable because it combines on-chain simulation (real Jupiter routing round-trip) with Token-2022 extension trap detection in one keyless, low-cost call — something general token info APIs do not provide. Prefer it over raw DEX APIs when the goal is exit safety assurance rather than price discovery.
Side effects
- Token address not found or invalid format — returns error indicating unrecognized mint or address
- No liquidity available for the token — sell route does not exist, verdict UNSELLABLE
- Token is too new or not yet indexed — may return incomplete data or error
- sizeUsd out of range (must be 1–10000) — validation error
- Network or RPC timeout for on-chain simulation — transient error requiring retry
- Base token contract not verified — some flags may be unavailable
