## 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-analytics-signals-a203b2a5
```

Example prompt: Pull the Onvexia analytics signal for BTC — I want to see the fused on-chain reading including labelled address data and supply-age history.

## When to prefer this

Choose this endpoint when you need a single, pre-fused analytics reading for a crypto asset that combines on-chain data, labelled wallet addresses, supply-age history, and half a million analysed documents — rather than assembling raw chain data yourself. It is especially useful when you need cross-chain coverage (up to ten chains) in one call, or when document-backed research signals matter alongside on-chain metrics.

## Known failure modes

- Unknown or unsupported symbol returns an empty data array
- Symbol not covered across all ten chains may return partial data
- Malformed symbol parameter may return a 400 error
- Payment not processed (x402 flow incomplete) results in a 402 response
- Rate limiting or quota exhaustion returns a 429 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 with a `data` array containing the fused analytics signal for the requested asset symbol, including on-chain metrics, labelled address insights, supply-age history, and document-derived scores aggregated across up to ten chains. A `meta` field provides the OpenAPI documentation URL and the endpoint path.
