title: Data AVAX Supply EVM Chains API
description: The Data API provides web3 application developers with multi-chain data related to Avalanche's primary network, Avalanche subnets, and Ethereum. With Data API, you can easily build products that leverage real-time and historical transaction and transfer history, native and token balances, and various types of token metadata. The API is in Beta and may be subject to change.</br></br>If you have feedback or feature requests for the API, please submit them <a href="https://portal.productboard.com/dndv9ahlkdfye4opdm8ksafi/tabs/4-glacier-api">here</a>. Bug reports can be submitted <a href="https://docs.google.com/forms/d/e/1FAIpQLSeJQrcp7QoNiqozMDKrVJGX5wpU827d3cVTgF8qa7t_J1Pb-g/viewform">here</a>, and any potential security issues can be reported <a href="https://immunefi.com/bounty/avalabs">here</a>.
