## 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 carbon-cashmere-mean-reversion-analytics-sol-519e52e5
```

Example prompt: Pull the mean-reversion analytics for SOL right now — I want to see the z-scores to the 20, 50, and 200-bar moving averages, the Ornstein-Uhlenbeck half-life, and whether it's statistically mean-reverting.

## When to prefer this

Use this endpoint when you need quantitative mean-reversion metrics specifically for SOL, including statistically grounded z-scores and Ornstein-Uhlenbeck parameters. Prefer this over generic price endpoints when you need to know whether an asset is statistically likely to revert to its mean, how far it has deviated, and on what timescale reversion is expected. Ideal for quantitative strategies, systematic trading signals, and risk assessment workflows.

## Known failure modes

- SOL price data unavailable — upstream data feed failure
- Invalid or unsupported asset symbol in path
- Rate limiting or payment failure via x402 micropayment protocol
- Service downtime resulting in 5xx response
- Stale or lagging data if price feed is delayed

## Output

A JSON object containing the SOL symbol, z-scores to 20/50/200-bar moving averages, Ornstein-Uhlenbeck half-life in days, a boolean indicating whether the asset is mean-reverting, the OU lambda per bar, and a reversion probability value (0–1), plus a disclaimer that data is informational only.
