Ankr Advanced API
Ankr Advanced API — enriched JSON-RPC methods for fetching NFTs, tokens, transactions, balances, and on-chain query data across 20+ EVM chains. All requests are POSTed to the multichain endpoint with a standard JSON-RPC 2.0 body; the method field selects the operation.

Demo key. Code samples and the interactive panel ship with a shared public demo key so every request works out of the box. It is heavily rate-limited and some methods are restricted on it — get your own API key at https://www.ankr.com/rpc/ for real usage. The key is part of the endpoint URL path (
https://rpc.ankr.com/multichain/<API_KEY>); no auth header is needed.
