# Supported blockchains and chain IDs for Zerion API

> Reference list of mainnet and testnet blockchains supported by Zerion API, with chain IDs and coverage for tokens, transactions, and NFTs.

<Tip>
  Building something that needs to stay current? Call the [chains endpoint](/api-reference/chains/get-list-of-all-chains) to fetch this list at runtime instead of hard-coding it. This page is regenerated from that same endpoint every day.

## Mainnets

Use the chain ID in filter parameters such as `filter[chain_ids]`.
