FAQ
Use Zerion’s unified schema to read wallet data across Optimism: token metadata and prices, NFTs, transactions, and normalized portfolio data. For holdings, protocols, and LPs, call the **/positions** endpoint. It aggregates all positions into a consistent structure so you can render portfolios without custom parsers.
Raw balances can miss protocol-level context and require bespoke indexing. The **/positions** endpoint returns position-aware data (e.g., lending deposits/borrows, staked assets, LP shares, vaults, and NFT collections) already resolved and normalized. This reduces engineering effort and improves UX consistency across chains.
Yes. Zerion API exposes the same object model across chains. Your integration against **/positions** on Optimism will work the same on Ethereum and other supported networks, simplifying multi-chain product development.
No. Zerion API abstracts node connectivity, indexing, and caching. You integrate endpoints like **/positions** and **/transactions** while we keep infra healthy, scalable, and up to date.
Create an API key, pick a known address, and hit **/positions** to retrieve normalized DeFi/NFT holdings. Then layer in **/transactions** to show activity and **/tokens** for metadata and pricing. You’ll have a production-ready portfolio view in minutes.
