# 402.com.tr Pre-Trade Gate

> 402.com.tr Pre-Trade Gate is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Runs a combined token risk, honeypot/tax, route/price-impact, and deployer reputation check on a Base token, returning a single GO/HOLD/STOP verdict with an auditable receipt.

## 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 402-com-tr-pre-trade-gate-1a962e3f
```

Example prompt: Before I buy any of this token at contract address 0x1234...abcd on Base, run a full pre-trade safety check — honeypot, sell tax, deployer reputation, and price impact — for a $500 trade size and tell me if it's a GO, HOLD, or STOP.

## When to prefer this

Use this endpoint when you need a single consolidated pre-trade safety verdict for a Base token instead of running four separate checks (risk, honeypot, route, deployer). It is cheaper than calling each check individually and returns an auditable receipt, making it ideal as the first gate before any token purchase or swap on Base.

## Known failure modes

- Invalid or non-existent token contract address returns an error or empty result
- Token not deployed on Base chain causes lookup failure
- amountUsd missing defaults to no price-impact analysis
- Service unavailable or payment failure returns HTTP error
- Unverified or very new deployer may result in incomplete reputation data

## How this service works

The single call an agent makes before touching a Base token: token risk + sellability (honeypot/tax) + route/price-impact + deployer reputation, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Cheaper than the four checks à la carte. This is the tool to bind first.

## Output

Returns a single GO/HOLD/STOP verdict plus the underlying sub-scores: token risk rating, honeypot/tax flags, route and price-impact analysis, and deployer reputation — all bundled into one auditable receipt.
