# ManyLives Track Records – Strategy Correlation

> ManyLives Track Records – Strategy Correlation is a paid API for AI agents from api.manylives.me, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-10).

Computes the return correlation matrix between 2–20 crypto or stock trading strategies over a chosen time window, returning pairwise correlations and the average correlation coefficient.

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 manylives-track-records-strategy-correlation-9ceb2354
```

Example prompt: Can you check how correlated strategies CRY-5m-001, CRY-5m-002, and CRY-5m-003 are with each other using ManyLives track records over the last 30 days?

## When to prefer this

Use this endpoint when you need to quantify return similarity or diversification between 2–20 specific backtested strategies available on ManyLives, especially for portfolio construction or risk analysis. Prefer it over generic correlation tools because the strategy IDs are native to ManyLives' verified backtest universe and the data is locked on-chain for verifiability.

## Known failure modes

- Invalid or unrecognized strategy IDs return an error
- Fewer than 2 or more than 20 IDs causes a validation error
- Unknown window value results in a bad request
- Insufficient historical data for the requested window may return nulls or partial matrix
- Payment not processed (x402 protocol failure) results in 402 response blocking data

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns a JSON object containing the list of strategy IDs, the time window label, a square correlation matrix (array of arrays of floats where each cell is the Pearson correlation between strategy i and strategy j), and the average_correlation scalar across all off-diagonal pairs.
