# Arc Bundle Check: Dev Buy & Rug Detection

> Arc Bundle Check: Dev Buy & Rug Detection is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).

Analyzes an Arc launchpad token or Uniswap v4 pool to detect bundled launches, developer self-buys, and coordinated early buying from funded wallets.

## 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 arc-bundle-check-dev-buy-rug-detection-15ea3bbb
```

Example prompt: Can you check if the Arc token at 0x4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b was bundled at launch — like did the dev buy their own supply or fund other wallets to snipe it early?

## When to prefer this

Use this endpoint when you need to assess whether a specific Arc launchpad token or Uniswap v4 pool was manipulated at launch via bundling, developer self-buying, or coordinated sniper wallets. It is uniquely suited to the Arc ecosystem and traces USDC funding chains in the hours before launch — something generic token screeners do not do. Prefer this over broad token screeners when you have a specific contract or pool address and need forensic-level launch analysis.

## Known failure modes

- Invalid or non-Arc token address returns an error
- Pool ID not found on Arc's Uniswap v4 deployment
- Neither token nor pool parameter provided
- Token launched too recently for full 2-minute buy window analysis
- USDC funding chain data unavailable for the pre-launch period
- Rate limiting or payment failure for the $0.004 x402 call

## How this service works

Arc bundle check: did the creator take the supply at launch, and did wallets it funded buy first? Was this Arc launch bundled? Pass ?token=0x... or ?pool=<v4 pool id>. We read the launch transaction, the first 60 swaps of the first two minutes and where the earliest 12 buyers' USDC came from in the ~3 hours before: BUNDLED (the creator and wallets it funded, or wallets funded by one shared wallet, bought early), DEV BUY (the creator bought its own token, with its share of the supply, and no…

## Output

Returns a verdict (BUNDLED, DEV BUY, or RUG) along with details about the creator's wallet activity, which wallets bought early, USDC funding chains traced ~3 hours before launch, and whether early buyers share a common funding source — giving a full picture of launch manipulation.
