# Launch Sniper Check

> Launch Sniper Check is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).

Analyzes a token's earliest transfers to detect sniped/bundled launches, dangerous holder concentration, or organic distribution, returning first holders and a launch-quality verdict.

## 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 launch-sniper-check-20442001
```

Example prompt: Can you check if this token at 0x1234...abcd was sniped or bundled at launch — look at the first 40 transfers and tell me if the early distribution looks organic or coordinated?

## When to prefer this

Use this endpoint when you need to quickly assess the launch integrity of a token on Base — specifically to detect sniping, bundling, or dangerous early concentration patterns. Pairs well with b20-launch-radar and Deployer Reputation for a fuller picture. Prefer this over general token analytics when the specific question is about coordinated early-block activity or launch fairness.

## Known failure modes

- Invalid or non-existent token contract address returns an error or empty result
- Token with no transfer history returns no data
- Network timeouts when fetching on-chain transfer history
- Very new tokens may have insufficient data for a meaningful verdict
- The 'first' parameter set too low may miss relevant early sniper activity

## How this service works

Reads a token's EARLIEST transfers to judge how it was launched: many recipients in a single early block or a tight block span is a sniped/bundled launch (coordinated, expect correlated dumping); very few early holders is dangerous concentration; a spread is organic. Returns the first holders and a verdict. The launch-quality read that pairs with b20-launch-radar — a heuristic, not proof. Pass first= (default 40). Not financial advice.

## Output

Returns a list of the token's earliest holders (transfer recipients) and a heuristic verdict on launch quality: whether the launch appears sniped (many recipients in a single early block), bundled (tight block-span coordination), dangerously concentrated (very few early holders), or organic (spread-out distribution). Intended as a risk signal, not definitive proof.
