How this service works
Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.
Output
An array of JSON:API resource objects, each representing a position held by the wallet — including asset type, protocol, chain, and value attributes — plus pagination links for iterating through large portfolios.
Example use cases
DeFi portfolio audit for a trader
“Pull up all the current DeFi positions for my wallet 0xAbCd1234...5678 — I want to see everything I'm holding across Ethereum, Arbitrum, and any other chains.”
Onchain due diligence for a DAO wallet
“Can you look up what positions the DAO treasury at 0xDeAd...BeeF is currently holding across all chains so we can review our DeFi exposure before the governance vote?”
Multi-chain wallet snapshot for a Solana user
“What's currently in the Solana wallet 7xKp...mN9Q? I want to see all the token and DeFi positions it holds right now.”
Technical details
Endpoint
GEThttps://api.zerion.io/v1/wallets/%7Baddress%7D/positions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a parsed, human-readable breakdown of all DeFi and token positions held by a specific wallet across 40+ EVM chains and Solana — particularly when you need cross-chain coverage in a single call. It outperforms raw RPC calls because Zerion interprets the on-chain data (protocol labels, USD values, position types) rather than returning raw contract state. The x402 pay-per-call model makes it cost-effective for agents making sporadic or one-off queries without a subscription.
Side effects
- Invalid or malformed wallet address returns a 400 error
- Address with no positions returns an empty data array
- Unsupported chain or address format may return no results
- Payment not settled via x402 returns 402 Payment Required
- Rate limiting may return 429 Too Many Requests
- Zerion API downtime or maintenance returns 503
