## 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-correlation-matrix-9d9730c8
```

Example prompt: Pull the correlation matrix from Losbeto's markets API so I can see how crypto assets are moving relative to each other and identify which pairs are most tightly correlated right now.

## When to prefer this

Choose this endpoint when you need pairwise asset correlation data for quantitative crypto trading strategies, portfolio construction, or risk analysis — especially within a USDC micropayment x402 framework on Solana or Base. Prefer this over building your own correlation computation when you want a pre-computed matrix without managing raw price data pipelines.

## Known failure modes

- Invalid or unrecognized property filter returns empty or error response
- Payment failure via x402 results in 402 status and no data
- Service downtime or market data feed lag may return stale or null matrix
- Malformed request properties field returns 400 bad request
- Insufficient USDC balance causes payment rejection before data is returned
