## 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-whale-exchange-flows-summary-2c7b1296
```

Example prompt: Pull me the whale exchange flow summary from Onvexia — I want to see whether large holders are net depositing or withdrawing across major chains right now so I can gauge selling pressure.

## When to prefer this

Choose this endpoint when you need aggregated whale-level exchange flow intelligence — specifically net inflows and outflows from large holders — rather than raw transaction data or individual address lookups. It is best suited for macro sentiment analysis, detecting institutional accumulation or distribution patterns, and informing trading decisions based on on-chain behavior. Prefer Onvexia's summary endpoint over generic block explorers when you need pre-processed, labelled whale activity fused across multiple chains in a single call.

## Known failure modes

- Empty data array returned if no whale flow data is available for the requested asset or chain
- Invalid or missing properties parameter may result in an empty or generic response
- Payment not processed (402) if x402 payment header is missing or USDC balance is insufficient
- Rate limiting or authentication errors if API key is invalid
- Stale or incomplete data if the specific chain or asset has limited coverage

## 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 a data array containing summarized whale exchange flow metrics (likely including net flow, inflow volume, outflow volume, and asset/chain identifiers) and a meta object with documentation links and the endpoint path. Actual data fields depend on the asset and time range queried.
