## 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-netflow-top-ranking-api-bbd9b355
```

Example prompt: Show me the top 10 assets ranked by netflow for a spot trade type over the last 24 hours — I want to see which ones have the strongest net inflows right now.

## When to prefer this

Use this endpoint when you need a ranked leaderboard of assets or trading pairs by netflow — especially for identifying top net-inflow assets in crypto markets without needing API keys or registration, paying per call with USDC via the x402 protocol.

## Known failure modes

- Empty data array returned when no assets match the filter criteria
- Invalid or unsupported type/trade/duration parameter values cause unexpected empty results
- Rate limiting or payment failure via x402 protocol returns HTTP 402
- Malformed query parameters result in a non-zero code in the response

## How this service works

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