## 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 mpp-hyreagent-fun-0155aa8c -d '<json body>'
```

Example prompt: Can you check if the PumpFun token HZ1JovNiVvGrGNiiYvEozEVgZ58xaU3RKwX8eACQBCt3 was sniped at launch — I want to see which wallets bought in the first 3 blocks, the overall sniper risk level, and whether any of those wallets are linked to the dev?

## When to prefer this

Use this endpoint when you need to assess launch-time sniper activity on a specific PumpFun token — particularly when evaluating whether a token launch was manipulated, whether insiders coordinated early buys, or whether the developer is linked to early snipers. Prefer this over general holder analysis when the concern is specifically about block-0 to block-3 buying behavior.

## Known failure modes

- Invalid or non-PumpFun token address returns error
- Token not found on PumpFun returns 404 or empty result
- Token too new with insufficient block data
- Payment not included or insufficient USDC returns 402
- Network timeout on Solana RPC lookups

## How this service works

Sniper detection

## Output

Returns a list of wallets that purchased the token within the first 3 blocks of its PumpFun launch, a sniper risk level (e.g. low/medium/high), and flags indicating whether any sniper wallets appear linked to the developer wallet.
