## 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-upbit-low-ranking-netflow-35e81d32
```

Example prompt: Show me the net capital flow for the lowest-ranked tokens on Upbit for the past 24 hours — limit it to the top 20 results.

## When to prefer this

Choose this endpoint when you specifically need net capital flow data for low-ranking or small-cap tokens on the Upbit exchange and want to pay per-call with USDC via the x402 protocol rather than managing API keys or subscriptions.

## Known failure modes

- Empty data array returned if no low-ranking netflow data is available for the requested period
- Invalid duration or limit parameter values may yield empty results or error responses
- Payment failure via x402 protocol results in 402 response if USDC balance is insufficient
- Network timeout or upstream Upbit data unavailability may cause partial or no data
- Unsupported query parameter combinations may silently return empty arrays

## 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 code field (0 for success) and a data array containing netflow metrics for low-ranking tokens on Upbit, such as per-token net buy/sell volumes or inflow/outflow values over the requested duration.
