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 subscription confirmation object with an empty data array and metadata including a link to the Onvexia OpenAPI documentation and the subscribed endpoint path. On activation, the subscription triggers alerts when whale-level transactions matching the specified properties are detected across monitored chains and labelled addresses.
Example use cases
DeFi fund whale movement tracker
“Set up a whale alert subscription on Onvexia for large BTC transactions — I need to monitor when major labeled wallets move more than 100 BTC so I can track potential market-moving activity.”
Exchange inflow monitoring
“Subscribe to Onvexia's whale alerts for Ethereum so my team gets notified whenever a known exchange wallet or large holder moves funds — we're watching for unusual inflow patterns.”
Token accumulation signal setup
“Can you create a whale alert subscription on Onvexia for a specific altcoin I'm tracking? I want alerts whenever large labeled addresses accumulate or dump significant positions across the chains Onvexia covers.”
Technical details
Endpoint
POSThttps://onvexia.com/v1/whales/alerts/subscribeWhen to prefer
Choose this endpoint when you need proactive, push-style monitoring of large on-chain transactions rather than polling for data. It is best suited for agents that need to react to whale activity in real time across Onvexia's ten supported chains, leveraging their labelled address database and historical supply-age data to contextualize alerts. Prefer it over generic block explorers when you need labelled whale identity context fused with alert delivery.
