FAQ
Use the **/positions** endpoint to retrieve normalized holdings across DeFi protocols and NFTs. Positions like lending, staking, LPs, and vaults are resolved so you don’t maintain bespoke indexers.
Combine **/positions** with **/transactions** to surface recent activity, and fetch token metadata/prices to label assets and compute valuations with consistent symbols, names, and decimals.
No. Zerion API normalizes data behind a unified object model. Your ZKsync integration resembles other EVM chains, minimizing chain-specific code.
Yes. Endpoints are engineered with robust indexing and caching to deliver low P99 latency in production.
Create an API key, pick a known ZKsync address, call **/positions** to render holdings, then wire **/transactions** and token metadata for a complete view.
