## 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-metrics-b5b6480e
```

Example prompt: Pull the Onvexia on-chain metrics for bitcoin — I want to see the supply-age history, labelled address breakdown, and any document-backed intelligence fused into a single reading.

## When to prefer this

Choose this endpoint when you need deep, fused on-chain analytics for a specific cryptocurrency asset — particularly when labelled address data, supply-age history, or document-backed intelligence are required. It is especially strong for assets on the ten supported chains with historical data back to 2008. Prefer it over generic blockchain explorers when you need a single synthesized analytical reading rather than raw transaction data.

## Known failure modes

- Invalid or unknown asset slug returns empty data array
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many calls are made in rapid succession
- Slug format errors if asset identifier is malformed
- No data available for very new or obscure assets not yet indexed

## 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 fused on-chain analytics for the requested asset slug, including labelled address data, supply-age history reaching back to 2008, document-backed intelligence derived from half a million analysed documents, and aggregated metrics across up to ten chains. Metadata includes a link to the full OpenAPI spec.
