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:
Mainnets:
- Ethereum
- Fantom
- BNB Smart Chain
- Polygon
- Avalanche
- Arbitrum
- Syscoin
- Optimism
Testnets:
- Ethereum Goerli
- Polygon Mumbai
- Avalanche Fuji
And more EVM and non-EVM chains coming soon.

Advanced APIs PAYG Pricing
The price of our API Credits is pegged to USD. It means that upon using ANKR tokens for PAYG, ANKR
calculates into API Credits
at the latest ANKR/USD exchange rate.
Our PAYG pricing model:
0.10 USD = 1M API Credits
