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 object with a `data` array containing ranked wallet addresses and their holdings for the requested asset, plus a `meta` object with documentation links and the endpoint path. Addresses may include Onvexia's proprietary labels (e.g. exchange names, known funds) derived from their labelled address database.
Example use cases
DeFi token concentration risk check
“Before I invest, can you pull the top holders for AAVE on Ethereum from Onvexia? I want to see if a handful of whales control most of the supply.”
Whale wallet monitoring for trading signals
“Get me the top 20 holder addresses for Uniswap's UNI token — I want to track whether whales are accumulating or distributing.”
Research report on token distribution
“I'm writing a report on Solana's token distribution. Pull the top holders list from Onvexia so I can quantify how concentrated the supply is.”
Technical details
Endpoint
GEThttps://onvexia.com/v1/whales/top-holdersWhen to prefer
Choose this endpoint when you need a ranked, labelled list of the largest token holders for a specific on-chain asset, especially when address labelling (e.g. identifying known exchanges or funds) and cross-chain coverage matter. Prefer this over generic blockchain explorers when you need structured, enriched whale data via a simple REST call with per-query micropayment pricing.
Side effects
- Unknown or unsupported asset/chain returns an empty data array
- Malformed properties parameter returns a schema validation error
- Payment not received (x402) causes a 402 Payment Required response
- Rate limiting or quota exceeded returns a 429 error
- Internal data pipeline delay may return stale or partial holder data
