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.
Example use cases
Detect whale selling pressure before trading
“Are whales currently moving large amounts of Bitcoin onto exchanges? Pull the Onvexia exchange flow summary so I can see net inflows and decide whether to reduce my position.”
Monitor institutional accumulation signals
“Check the whale exchange flow summary for Ethereum — I want to know if large holders are withdrawing from exchanges, which could signal accumulation before a price move.”
On-chain sentiment check for portfolio review
“Give me a quick summary of whale exchange flows across the top chains on Onvexia — I'm doing a weekly portfolio review and want to see which assets have unusual large-holder activity.”
Technical details
Endpoint
GEThttps://onvexia.com/v1/whales/exchange-flows/summaryWhen to prefer
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.
Side effects
- 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
