## 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 criptonous-x402-dionisio-heat-signal-1b8486b8
```

Example prompt: Pull the CriptoNous dionisio heat signal for SOL — I want to see whale flow, smart money movement, and sentiment right now.

## When to prefer this

Choose this endpoint when you need real-time on-chain crypto market intelligence — specifically whale flow, smart money positioning, sentiment, and oracle signals — for a specific token, and are willing to pay a $0.03 USDC micropayment per query via x402. It is best suited for agents operating in DeFi or crypto trading contexts on Solana. Prefer alternatives if you need free or subscription-based data, historical bulk data, or coverage beyond the token symbols supported by CriptoNous.

- Unsupported or unrecognized token symbol — may return empty or error response
- Endpoint temporarily unavailable on Railway hosting — returns 5xx
- Rate limiting or quota exceeded — returns 429
