## 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-b140b8c2
```

Example prompt: Pull the latest Nansen flow data so I can see current on-chain smart money movements for my trading strategy.

## When to prefer this

Choose this endpoint when you need Nansen-sourced on-chain smart money flow analytics and want to pay per-call via USDC micropayment (x402) rather than maintaining a full Nansen subscription. Best for AI trading agents that need intermittent on-chain flow signals without a long-term API commitment.

## Known failure modes

- Payment not included or insufficient USDC (402 response)
- Invalid or missing properties parameter returns malformed response
- Nansen upstream API unavailable causes 502/503
- Rate limiting if too many requests in short window
- Empty result set if no flow data matches filter criteria
