## 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-asset-correlation-analytics-b2286fae
```

Example prompt: Pull the Onvexia correlation analytics for BTC — I want to see how it moves relative to other assets across chains based on their on-chain and document data.

## When to prefer this

Choose this endpoint when you need cross-asset correlation metrics grounded in both on-chain data (labelled addresses, supply-age history) and document-level analysis across up to ten blockchains. It is especially valuable when you need historically deep correlation data reaching back to 2008 and covering a broad universe of thousands of assets, rather than simple price-correlation tools that rely only on market data.

## Known failure modes

- Unknown or unsupported symbol returns empty data array
- Symbol format mismatch causes no results
- Payment not processed (402) blocks response
- Rate limiting if call quota exceeded
- Malformed symbol path parameter returns error

## 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

A JSON object containing correlation data for the requested asset symbol, including cross-asset relationship metrics derived from multi-chain on-chain data, labelled addresses, and analysed documents. The meta field points to full API documentation at onvexia.com/openapi.json.
