Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 tokenguard-correlation-api-4150b24f -d '<json body>'
```

Example prompt: What's the price correlation between WETH and USDC on Base over the last 30 days — are they moving together or inversely?

## When to prefer this

Choose this endpoint when you need to quantify the statistical relationship between two or more crypto/DeFi assets — particularly for portfolio risk analysis, hedging strategy, or identifying co-movement patterns on-chain. Prefer it over general market data endpoints when the specific output needed is a correlation coefficient rather than raw price or volume data.

## Known failure modes

- Invalid or unrecognized token address returns error
- Unsupported blockchain network or token pair returns empty or null result
- Insufficient historical data for the requested time range causes computation failure
- Malformed request body returns 400-level error
- Micropayment (x402) authorization failure blocks the call
- Rate limiting or service unavailability on HuggingFace Spaces infrastructure

## How this service works

correlation data for AI agents.

## Output

Returns a JSON object containing correlation coefficients (typically ranging from -1 to 1) between the specified crypto asset pairs or data series, along with any supporting statistical metadata such as sample size or time window used in the computation.
