## 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 vextorium-pre-trade-token-risk-liquidity-check-e78cf29f -d '<json body>'
```

Example prompt: Before I buy $2000 worth of this token — 0x1234...abcd on Ethereum — can you check if it's safe, what the main pool liquidity looks like, how much my trade would move the price, and what slippage I should set?

## When to prefer this

Use this endpoint when an AI agent or user needs a pre-trade safety check on a specific token before executing a swap on Base, Ethereum, Arbitrum, Optimism, Polygon, or Solana. It uniquely combines contract-level risk analysis (honeypot detection, contract permissions), real DEX liquidity data, trade-size-aware price impact estimation, and a concrete slippage recommendation — all in a single call. Prefer it over generic token info APIs when the user's goal is to decide whether and how to trade safely, not just to look up a price.

## Known failure modes

- Token address not found on specified network — empty or null pool data returned
- Unsupported network specified — validation error on 'red' enum field
- Token contract cannot be analyzed — partial result with nulls in risk fields
- Importe_usd not provided — price impact and slippage recommendation may be null
- Network congestion causes timeout — upstream RPC or DEX data unavailable
- Malformed token address — request rejected with schema validation error

## How this service works

Before buying or selling a token: risk verdict (contract powers, honeypot pattern, age), main pool liquidity, estimated price impact for your USD amount, recommended slippage and a decision (ok, caution, avoid). Base, Ethereum, Arbitrum, Optimism, Polygon or Solana.

## Output

Returns a structured object with: the token symbol, risk object (level: low/medium/high, numeric score, array of risk signals such as honeypot pattern or dangerous contract powers), a decision field (ok/caution/avoid), motivos array with human-readable reasons, the main pool details (DEX name, pair, price in USD, liquidity in USD, link), the estimated price impact percentage for the given USD amount, and the recommended slippage percentage.
