How this service works
An origin the crawlers already index. We count what AI agents try to buy, what they are refused, and what the AI companies take without sending anyone back. Sold per call in USDC.
Output
A JSON object containing: a square pairwise correlation matrix keyed by ticker symbol, the time period used, list of tickers, number of daily bars used in the calculation, a portfolio diversification score (0–1, lower = less diversified), and a ranked list of the strongest correlated ticker pairs with their correlation coefficients.
Example use cases
Example prompt
“Can you compute the correlation matrix for NVDA, AMD, MSFT, and QQQ over the past year and tell me which pairs are most correlated and how well-diversified that mix is?”
Technical details
Endpoint
GEThttps://market2000.xyz/correlation_matrixWhen to prefer
Use this endpoint when you need to quantitatively assess co-movement between multiple equities — particularly for portfolio construction, risk analysis, or hedging research. It is purpose-built for multi-ticker correlation analysis with a built-in diversification score, making it more useful than generic financial data APIs when the goal is understanding relationships between assets rather than fetching raw prices.
Side effects
- Invalid or unrecognized ticker symbols return an error or missing matrix entries
- Insufficient historical data for a ticker may reduce bars_used or cause partial results
- Payment failure via x402 results in a 402 response before computation
- Too many tickers in a single request may hit a rate or size limit
- Period parameter out of range or malformed returns a validation error
