## 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 losbeto-nansen-flow-on-chain-capital-flow-analytics-94c43a2f
```

Example prompt: Pull the Nansen flow data right now so I can see where smart money is moving — any major capital inflows or outflows I should know about?

## When to prefer this

Use this endpoint when you need Nansen-style smart money and capital flow analytics via a pay-per-call x402 USDC micropayment model, avoiding subscription costs. Prefer it for lightweight, on-demand on-chain intelligence queries where you want to pay only $0.05 per call.

## Known failure modes

- Missing or malformed properties parameter returns an error or empty result
- Upstream Nansen data unavailable causes a 5xx or empty JSON response
- Payment failure (insufficient USDC) results in a 402 response blocking access
- Invalid chain or token filter returns no matching flow data
