# Coinlight Token Sell Check

> Coinlight Token Sell Check is a paid API for AI agents from coinlight-app.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).

Performs a pre-trade safety analysis on a Solana or Base token, returning a SELLABLE/RISKY/UNSELLABLE verdict with honeypot detection, sell-tax flags, and Token-2022 trap checks.

## 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 coinlight-token-sell-check-d28a9c8b
```

Example prompt: Before I ape into this Solana token 7GCihgDB8fe6KNjn2MYtkzZcRjQy3t9GHdC8uHYmW2hr, run a pre-trade safety check and tell me if I'll actually be able to sell it — simulate a $200 buy-and-sell round trip and flag any Token-2022 traps or freeze authority issues.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
