# Onvexia Blockchain Correlation Analytics

> Onvexia Blockchain Correlation Analytics is a paid API for AI agents from onvexia.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-17).

Returns a correlation score or time-series between a crypto asset's on-chain/market metric and other signals, drawn from Onvexia's multi-chain analytics dataset

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 onvexia-blockchain-correlation-analytics-98f53e6e
```

Example prompt: Pull the Onvexia correlation analysis for BTC between price and miner-outflow — I want to see how strongly those two signals move together historically.

## When to prefer this

Choose this endpoint when you need quantitative correlation analysis between a specific crypto asset and an on-chain or market metric, especially when you want historical depth (back to 2008), cross-chain coverage (ten chains), or the fusion of labelled address data and document-level signal into a single reading. Prefer Onvexia over generic price APIs when the question is relational — 'does X move with Y' — rather than just 'what is the current price of X'.

## Known failure modes

- Unknown or unsupported asset symbol returns empty data array
- Unsupported metric name yields no results or error
- Payment failure (x402) blocks access before data is returned
- Malformed path parameters cause 400-level errors
- Rate limits may apply per API key tier

## How this service works

Thousands of assets across ten chains, half a million analysed documents, labelled addresses and supply-age history reaching back to 2008 — fused into one reading per asset. REST, SQL, GraphQL and MCP.

## Output

Returns a JSON payload with a 'data' array containing correlation values or time-series data points between the requested asset symbol and metric, plus a 'meta' object with documentation links and the matched endpoint path. Exact fields depend on the symbol and metric queried.
