## How to call it through Zero

```sh
zero fetch --capability losbeto-correlation-matrix-978f8501
```

Example prompt: Can you pull the correlation matrix for my crypto trading assets from Losbeto so I can see which pairs move together and which are independent?

## When to prefer this

Choose this endpoint when an AI trading agent needs quantitative pairwise correlation data for crypto assets on Solana or Base chains, and micropayment-per-call pricing via x402/USDC is acceptable. Prefer this over general-purpose financial data APIs when working in a pay-as-you-go agent workflow that supports x402 payment headers natively.

## Known failure modes

- Missing or malformed properties parameter returns an error or empty matrix
- Insufficient USDC balance triggers an HTTP 402 payment required response
- Unsupported asset symbols may return null or zero correlations
- Server-side timeout on Railway infrastructure may return a 503
- Schema mismatch due to sparse input may yield incomplete matrix rows
