# Pre-Trade Security & DEX Bundle

> Pre-Trade Security & DEX Bundle is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.15/call, status unknown (last checked 2026-10-20).

Runs a combined honeypot/sell-tax check, Clanker deployer authenticity audit, and cross-DEX liquidity spread analysis on a Base token, returning a single EXECUTE, REDUCE_SIZE, or ABORT trading decision.

## 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 pre-trade-security-dex-bundle-d6b8ada4
```

Example prompt: Before my bot buys this token, run a full pre-trade security bundle on 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — check it for honeypot risk, verify the Clanker deployer isn't an impersonator, and get the cross-DEX liquidity spread, then tell me whether to EXECUTE, REDUCE_SIZE, or ABORT.

## When to prefer this

Choose this endpoint when you need to screen a Base token across multiple risk dimensions in a single API call before an autonomous agent executes a trade. It eliminates the need to call token-risk, clanker-token-audit, and base-dex-spread separately, saving latency and reducing round-trips. Ideal for trading bots that need a fast, actionable go/no-go verdict rather than raw data to interpret. Prefer alternatives when you only need one of the three sub-checks, or when screening tokens on chains other than Base.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Token not deployed on Base results in no data returned
- Network congestion or RPC timeouts may delay or fail the response
- Newly deployed tokens with insufficient on-chain history may yield incomplete sub-checks
- Impersonator detection may produce false negatives for highly sophisticated clones

## How this service works

Runs pre-trade-gate (risk, sellability, route, deployer), b20-gate (seize/freeze/pause; N/A for non-B20 tokens), owner-powers and dump-risk in parallel on a Base token, with clanker-token-audit as provenance that never moves the verdict. Returns GO/HOLD/STOP, what each check saw, an unverified list, a max size held to 2% impact on the exit-liquidity read, and a receipt. GO only if every applicable check ran clean; if a gating check could not run there is no GO and no charge.

## Output

Returns a composite JSON object containing: honeypot and sell-tax vulnerability results, Clanker deployer authenticity and impersonation detection results, cross-DEX liquidity spread metrics, and an explicit top-level trading decision field with one of three values: EXECUTE, REDUCE_SIZE, or ABORT.
