## 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 pump-fun-bundle-insider-checker-4c9db715 -d '<json body>'
```

Example prompt: Can you run a standard bundle and insider check on this pump.fun token — mint address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU — and tell me the coordination risk score, who the early snipers are, and how much supply they still hold?

## When to prefer this

Choose this endpoint when you need on-chain forensic analysis of a specific pump.fun token's launch — especially to detect insider coordination, bundled buys, dev-funded wallets, or sniper accumulation before making a trading decision or flagging a token as risky. Prefer the max tier for deeper due diligence on high-value decisions or serial launcher checks.

## Known failure modes

- Invalid or non-pump.fun mint address returns a lookup failure (not charged)
- Public RPC rate limits may slow or fail analysis without a custom RPC URL
- Token with very few on-chain buyers may return incomplete early-buyer list
- Providing more than 1 token address in the array causes rejection (maxItems:1)
- Network timeouts on Solana RPC during high congestion

## How this service works

Who really bought a pump.fun token? Early buyers, snipers, bundles, wallets funded by one wallet or the dev, fresh and bot wallets, supply still held. Coordination risk %, verdict, summary. Signals, not advice. Up to 1 items per call; failed lookups are not charged.

## Output

Returns a structured report including: list of earliest buyers (30 for standard, 60 for max) with wallet labels (sniper, bot, fresh, dev-funded, bundled), funding hop graph showing wallet relationships, percentage of supply still held by insiders, coordination risk percentage, an overall verdict (e.g. high risk / low risk), and a plain-language summary. Max tier also includes the creator's other recent launches.
