## 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 claw402-rootdata-kol-rankings-api-e58d66ba
```

Example prompt: Can you pull me the top 20 crypto KOLs from RootData, ranked by influence — give me page 1 with a page size of 20 using the default rank type?

## When to prefer this

Use this endpoint when you need ranked crypto KOL data from RootData without registering for an API key, and you are able to pay per-call in USDC via the x402 protocol. Prefer this over traditional API key-gated services when you want frictionless, wallet-based access to influencer rankings.

## Known failure modes

- Payment not completed or insufficient USDC — 402 response requiring payment
- Invalid query parameter types for page, page_size, or rank_type — may return empty data or error
- Empty data array returned if no KOLs match the rank_type or page is out of bounds
- Service unavailable if vergex.trade backend is down

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

Returns a JSON object with a status code and a data array containing ranked KOL entries from RootData, such as influencer names, rankings, and associated metadata. Typical response: {code: 0, data: [...]}
