## How to call it through Zero

```sh
zero fetch --capability onvexia-asset-integrity-check-420c6526
```

Example prompt: Can you pull the Onvexia integrity check for ETH — I want to see the fused score, any labelled address flags, and supply-age history the platform has on it?

## When to prefer this

Choose this endpoint when you need a single, fused integrity reading for a blockchain asset that aggregates labelled address intelligence, historical supply data back to 2008, and document-level analysis across ten chains — rather than querying separate on-chain explorers, news sentiment APIs, or address labelling services independently. Best when you need a consolidated risk or legitimacy signal for a specific token by ticker symbol.

## Known failure modes

- Unknown or unsupported asset symbol returns empty data array
- Payment not processed results in 402 status before data is returned
- Malformed symbol parameter may result in validation error
- Asset not yet covered across all chains may return partial data
- Rate limiting or quota exceeded may block repeated calls

## 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 response containing integrity data for the requested asset symbol, including a fused integrity reading derived from labelled addresses, analysed documents, and supply-age history across up to ten chains. The meta field references the full OpenAPI spec for field-level documentation.
