> Onvexia Whale Transactions Feed is a paid API for AI agents from onvexia.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-17).

## 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-transactions-feed-cbb609f1
```

Example prompt: Show me the latest whale transactions across all tracked chains — I want to see who's moving large amounts and whether the addresses are labelled as exchanges or known funds.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
