## 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 onchain-risk-checks-max-memecoin-holder-trace-ce701518
```

Example prompt: Can you trace the early buyers of this pump.fun token — mint address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU — and tell me if there are any insider rings or if the creator is a serial launcher?

## When to prefer this

Choose this endpoint when you need deep memecoin-specific holder tracing for Solana pump.fun or Base tokens, particularly when you want to distinguish insider rings from generic sniper bots and profile the creator's full launch history. It goes beyond simple holder snapshots by tracing funding sources up to 2 hops and cross-referencing early buyers across the same creator's other launches. Prefer this over generic blockchain explorers or basic holder-count APIs when evaluating pre-buy risk on new memecoins.

## Known failure modes

- Invalid or unrecognized token mint address returns an error or empty result
- Token too new or not indexed on pump.fun/Base DEX returns no buyer data
- Token address on unsupported chain returns an error
- Rate limiting or payment failure (x402) blocks the response
- Creator has no prior launch history, returning empty creator track record

## How this service works

Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.

## Output

Returns a list of up to 60 early buyers with funding-hop traces (up to 2 hops, exchange hubs excluded), the creator's historical token launches with outcome summaries and a serial-launcher flag, and insider ring groupings distinguishing coordinated early buyers across the creator's launches from generic sniper bots.
