## How to call it through Zero

```sh
zero fetch --capability losbeto-nansen-flow-e8a85955
```

Example prompt: Pull the latest Nansen on-chain flow data for smart money wallet movements so I can see where capital is flowing right now.

## When to prefer this

Choose this endpoint when you need Nansen-style on-chain flow analytics with micropayment access ($0.05 USDC per call) via the x402 protocol, particularly for AI agents operating autonomously on Solana or Base that need smart money flow data without a monthly subscription.

## Known failure modes

- 402 Payment Required if USDC payment header is missing or insufficient
- Invalid or malformed properties parameter returns an error
- Rate limiting if too many calls are made in quick succession
- Upstream Nansen data unavailability may return empty or error response
- Schema ambiguity in input may cause unexpected results

## How this service works

Pay-per-call market data for AI agents: multi-oracle price consensus, sentiment consensus, forex, equities, commodities, macro and crypto. No API keys, no accounts. USDC on Base and Solana via x402.

## Output

Returns JSON containing on-chain token or wallet flow analytics in Nansen style, including smart money movement metrics, inflow/outflow volumes, and related on-chain transaction flow statistics.
