Advanced APIs Overview


Advanced APIs is a unique feature that comes along with other extensive capabilities provided to our Premium Plan users.

Advanced APIs is a specifically-tailored collection of JSON-RPC API endpoints built to support the most popular Web3 scenarios on multiple chains at almost instant speeds. We believe it to become a single point of reference for the multi-chain requests.


Advanced APIs optimize, index, cache, and store blockchain data to make it access-ready for you. To make things even better, our Advanced APIs support querying eight EVM-compatible blockchains in a single request.

Chains Supported

Currently, Advanced APIs work with the following EVM-compatible chains:

  • Ethereum
  • Fantom
  • Binance Smart Chain
  • Polygon
  • Avalanche
  • Arbitrum
  • Syscoin
  • Optimism

And more EVM and non-EVM chains coming soon.
