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 of whale entity records (labelled addresses and entity metadata) and a `meta` object containing coverage and provenance information including a link to the full OpenAPI spec. An empty data array means no whale entities were observed in the requested window, not that the feature is unsupported.
Example use cases
Monitor active whales before a trade
“Pull up the 100 most active whale entities from the last 6 hours so I can see if any major players are moving before I make my position.”
Identify labelled entities for compliance review
“Give me a list of labelled whale entities seen on-chain in the past 48 hours — I need the entity names and any coverage metadata for a compliance report.”
Research whale concentration in a market
“Who are the biggest on-chain whale entities Onvexia has labelled that were active in the last 12 hours? I want up to 50 results for my market research.”
Technical details
Endpoint
GEThttps://onvexia.com/v1/whales/entitiesWhen to prefer
Choose this endpoint when you need a quick, paginated list of recently-active labelled whale entities from Onvexia's multi-chain dataset, especially when entity identity and provenance metadata matter. Prefer it over generic block-explorer queries when you need pre-labelled, analytics-ready entity data rather than raw transaction records.
Side effects
- Empty data array if no whale entities appear in the requested time window (not an error)
- Limit capped at 100; requests above this will be silently clamped or rejected
- Invalid hours or limit parameter types may cause a 400 error
- 402 Payment Required if the x402 micropayment of 0.002 USDC is not included
- Meta null labels indicate no label is held, not that the address is safe or clean
