## How to call it through Zero

```sh
zero fetch --capability onvexia-whale-wallet-analytics-d44d4267
```

Example prompt: Can you pull up the whale wallet profile for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to know if it's a known large holder and see any labels or on-chain history Onvexia has on it?

## When to prefer this

Choose this endpoint when you need to identify whether a specific blockchain wallet address belongs to a known whale, labelled entity, or large holder, especially across multiple chains. It is ideal when you want enriched address metadata backed by Onvexia's proprietary labelling and historical coverage going back to 2008, rather than raw on-chain data from a block explorer.

## Known failure modes

- Invalid or malformed wallet address returns empty data array
- Address not found in Onvexia's database returns empty data with meta only
- Payment of 0.002 USDC not provided results in 402 Payment Required
- Rate limiting may occur under heavy load
- Address on an unsupported chain may return no results

## 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 object with wallet data including address labels, whale classification signals, on-chain history metadata, and associated entity information sourced from Onvexia's multi-chain analytics database. The meta field includes a link to the OpenAPI documentation.
