# MCX Ventures Cross-Source Correlation Analysis

> MCX Ventures Cross-Source Correlation Analysis is a paid API for AI agents from api.mcx-ventures.com, paid per call via x402, $3/call, status unknown (last checked 2026-09-14).

Analyzes a query or topic by correlating information across multiple provided sources or URLs to surface patterns, relationships, and synthesized insights.

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 mcx-ventures-cross-source-correlation-analysis-88206dc8 -d '<json body>'
```

Example prompt: Can you run a cross-source correlation analysis on whether central bank rate hikes reliably suppress inflation, using these three sources: [Fed policy paper URL], [IMF working paper URL], and [Reuters article URL]?

## When to prefer this

Choose this endpoint when you need to compare, contrast, or synthesize information from multiple distinct sources around a specific question or topic — especially when identifying patterns, agreements, or contradictions across heterogeneous inputs. Prefer it over single-source summarization endpoints when cross-source relationships are the goal. It is distinct from adversarial verification (which stress-tests claims) and deep synthesis (which aggregates without explicit correlation framing).

## Known failure modes

- Missing required query field returns validation error
- Sources array exceeds 20 items limit causing rejection
- Invalid URL in sources array may cause fetch failure or partial results
- Insufficient source content may yield low-confidence or empty correlation
- Network timeout if external URLs are slow to retrieve
- Ambiguous or overly broad query may produce generic analysis

## How this service works

Cross-source correlation analysis

## Output

Returns a structured correlation analysis identifying patterns, agreements, contradictions, and synthesized relationships found across the provided sources relative to the query. Output likely includes a summary of cross-source findings, key correlations or divergences, and supporting evidence drawn from the input texts or URLs.
