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 contract records for the specified asset — including contract addresses, chain identifiers, labelling metadata, and deployment details — plus a `meta` object with documentation links and the endpoint path.
Example use cases
Verify token contract before trading
“Before I buy, can you look up the official smart contract addresses for AAVE on all supported chains from Onvexia so I can confirm the token I'm being sent isn't a fake?”
Cross-chain deployment audit
“I need to know every chain that Uniswap's UNI token has a deployed contract on — pull the full list from Onvexia including any labelled addresses.”
DeFi integration contract lookup
“We're integrating USDC into our app — can you fetch all the verified contract addresses for USDC across Onvexia's ten supported chains so we can configure each network correctly?”

Endpoint
POSThttps://onvexia.com/v1/assets/%7Bid%7D/contractsWhen to prefer
Choose this endpoint when you need authoritative, labelled smart contract addresses for a specific crypto asset across multiple blockchains and want data fused from on-chain sources plus Onvexia's own analytical coverage — particularly when you need to distinguish legitimate contracts from counterfeits or need historical deployment context going back to 2008.
Side effects
- Asset ID not found returns empty data array
- Invalid asset ID format returns error
- POST body with malformed properties field may return 400
- Rate limiting or payment failure (x402) if USDC payment not attached
- Unsupported chain or asset outside Onvexia's ten-chain coverage returns no results
