    Ankr's Node API exposes standard JSON-RPC endpoints (HTTPS and WebSocket) for 80+
    public blockchains at rpc.ankr.com/{chain}. EVM chains share the Ethereum JSON-RPC envelope;
    non-EVM chains (Solana, Aptos, TRON, Stellar, TON, Cosmos networks) expose their native
    RPC surface at the same per-chain endpoint. Public Plan is open and anonymous;
    Premium Plan multiplies throughput x50 and unlocks WebSocket subscriptions, archive nodes,
    and IP whitelisting via project-scoped API keys.

    The Advanced API (AAPI) is Ankr's indexed JSON-RPC surface that optimizes, caches, and
    aggregates data across 19 EVM mainnets and 7 testnets. Methods are grouped into NFT
    (ankr_getNFTsByOwner, ankr_getNFTMetadata, ankr_getNFTHolders, ankr_getNftTransfers),
    Token (ankr_getAccountBalance, ankr_getCurrencies, ankr_getTokenPrice, ankr_getTokenHolders,
    ankr_getTokenHoldersCount, ankr_getTokenTransfers, ankr_getTokenPriceHistory), and Query
    (ankr_getBlockchainStats, ankr_getBlocks, ankr_getLogs, ankr_getTransactionsByHash,
    ankr_getTransactionsByAddress, ankr_getInteractions).

    Ankr's Liquid Staking developer surface — a RESTful metrics API plus on-chain Smart Contract
    APIs across Avalanche, Binance Smart Chain, Ethereum, Fantom, and Polygon. Supported
    liquid staking tokens include ankrETH, ankrBNB, ankrPOL, ankrAVAX, ankrFTM, ankrDOT, and
    ankrFLOW. The RESTful surface exposes staking metrics (TVL, APR, holders, supply),
    the trustless exchange ratio, and validator metadata (unbond windows, reward release).

    Ankr Contract Automation executes deployed smart-contract functions based on time-based (CRON)
    or event-driven (IAutomateCompatible) triggers. As of May 2026 the service supports BNB Smart Chain
    only — additional networks are on the roadmap. Tasks are created, funded, paused, and deleted via
    the Ankr Automation Dashboard.

  Ankr is a Web3 infrastructure provider whose multichain RPC, Advanced API, liquid staking,
  contract automation, and Rollup-as-a-Service products serve developers, exchanges, and
  enterprises across 80+ blockchains. The Node API exposes JSON-RPC and WebSocket endpoints at
  rpc.ankr.com/{chain}; the Advanced API (AAPI) layers an indexed query surface across 19 EVM
  mainnets for NFT, token, and historical-data reads. Ankr also operates liquid staking pools
  (ankrETH, ankrBNB, ankrPOL, ankrAVAX, ankrFTM, ankrDOT, ankrFLOW), a contract automation
  service on BNB Smart Chain, and an enterprise Rollup-as-a-Service practice that supports OP
  Stack, Polygon CDK, and Arbitrum Orbit variants. Infrastructure runs as a global DePIN of
  bare-metal nodes in 30+ regions serving roughly 8 billion daily RPC requests.
