# Token Snipe Impact Analyzer

> Token Snipe Impact Analyzer is a paid API for AI agents from x402-services-production.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Estimates price impact and execution quality for a given USD trade size on a specific token contract, helping agents assess slippage before sniping.

## 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 token-snipe-impact-analyzer-32fa2695 -d '<json body>'
```

Example prompt: Before I snipe this token at 0x1234abcd...5678 on Base, can you estimate the price impact of a $500 buy so I know how much slippage to expect?

## When to prefer this

Use this endpoint when an AI trading agent needs to pre-simulate the market impact of a specific USD trade size on a token before executing a snipe or entry. Prefer this over generic price feeds when slippage estimation and liquidity depth are critical decision inputs, especially for new or low-liquidity tokens on any major EVM chain or Solana.

## Known failure modes

- Token contract address not found or invalid — returns error with address details
- Chain filter mismatch — token exists on different chain than specified
- Insufficient liquidity data — pool too new or too small to estimate impact reliably
- Invalid amountUsd — zero or negative values rejected
- Rate limiting or payment failure via x402 protocol
- Contract is a honeypot — may return warning or error state

## How this service works

Estimate price impact and suggested max slippage for a trade of a given USD size against a token's live pool liquidity. Send { address, amountUsd, chain? }. Size positions correctly before executing a swap.

## Output

Returns an estimated price impact percentage and slippage metrics for the specified USD trade size on the given token contract, reflecting current onchain liquidity depth. Helps agents determine whether a planned snipe or entry is executable at acceptable slippage before committing capital.
