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

A JSON array of recent large on-chain transactions across tracked blockchains, each entry including transaction details, asset information, chain identifier, involved wallet addresses with labels where available, and associated metadata. The meta field points to the full OpenAPI documentation.

Example use cases

Pre-trade whale signal detection

“Before I make a large ETH purchase, pull the most recent whale transaction feed and tell me if any major addresses are dumping or accumulating — I want to know if smart money is moving in or out.”

DeFi protocol monitoring

“Keep an eye on the whale transactions feed for any large movements involving labelled exchange or protocol wallets on the chains Onvexia covers, and alert me if anything unusual shows up in the next hour.”

Market intelligence reporting

“Pull the current whale transactions feed and summarize the top 10 largest on-chain moves from today, including which addresses are labelled and what assets they were moving, so I can include it in my crypto market update.”

Technical details

Endpoint

GEThttps://onvexia.com/v1/whales/transactions/feed

When to prefer

Choose this endpoint when you need a real-time stream of large on-chain transactions with pre-labelled addresses and multi-chain coverage in a single call. It is particularly valuable over raw blockchain node queries when address labelling (exchange, fund, whale) and cross-chain aggregation are needed without building your own indexer.

Side effects

Empty data array returned if no whale transactions match the applied filters
402 Payment Required if USDC micropayment of $0.002 is not included or fails
Malformed properties parameter may result in empty or unexpected results
Rate limiting if the feed is polled too aggressively
Chain or asset not covered by Onvexia returns no results
