Overview

Start using Advanced API on RPC Service (opens in a new tab).

Advanced API 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 API optimizes, indexes, caches, and stores blockchain data to make it access-ready for you. To make things even better, our Advanced API supports querying ten EVM-compatible blockchains in a single request.

Chains Supported

Currently, Advanced API works with the following EVM-compatible chains:

Mainnets:

• Avalanche, Arbitrum, Base, BNB Smart Chain, Ethereum, Fantom, Flare, Optimism, Polygon, Polygon zkEVM, Rollux, Syscoin.

Testnets:

• Avalanche Fuji, Ethereum Goerli, Optimism Testnet, Polygon Mumbai.

And more EVM and non-EVM chains coming soon.

API Methods Supported

• ankr_getNFTMetadata — retrieves metadata of a particular NFT.
• ankr_getNFTHolders — retrieves holders of a particular NFT.
• ankr_getNftTransfers — retrieves NFT transfers info of a particular address.

• ankr_getBlockchainStats — retrieves blockchain statistics.
• ankr_getBlocks — retrieves full info of a particular block.
• ankr_getLogs — retrieves history data of a particular block range.
• ankr_getTransactionsByHash — retrieves the details of a transaction specified by hash.
• ankr_getTransactionsByAddress — retrieves the details of a transaction specified by wallet address.
• ankr_getInteractions — retrieves blockchains interacted with a particular wallet.
• [ankr_getInternalTransactionsByBlockNumber]/advanced-api/query-methods/#ankr_getinternaltransactionsbyblocknumber) — retrieves info on internal transactions by block number.
• ankr_getInternalTransactionsByParentHash — retrieves info on internal transactions by parent hash.

Token API

Token API Methods serve to request token-related data across multiple chains:

• ankr_getAccountBalance — retrieves the balance of a particular account.
• ankr_getCurrencies — retrieves a list of currencies used on a particular blockchain.
• ankr_getTokenPrice — retrieves the price of a particular token.
• ankr_getTokenHolders — retrieves info on holders of a particular token.
• ankr_getTokenHoldersCount — retrieves the number of token holders.
• ankr_getTokenTransfers — retrieves token transfers info.

Advanced API 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

Support and Developer Community

Our goal is to provide developers with the best user experience possible and supercharge Web3 projects with our Advanced API. Also, we strongly believe that community feedback fills our sails. So, let's team up — join our Discord community (opens in a new tab) to get support from our team, engage with like-minded developers, and propose new features that we can add in our Roadmap.
