The server endpoint returns the state of the ledger itself: the latest validated ledger index and age, the base and per-object XRP reserves, the current fee and the node software version — the network health a wallet or explorer needs. Everything is read live from the XRPL, nothing stored. This is the XRP Ledger on-chain layer for any wallet, explorer, exchange, payments or analytics app. Distinct from EVM and Solana on-chain APIs and from price feeds — this is XRPL account state, token balances, transactions and ledger health. 4 endpoints, no key on our side.

Live Solana blockchain data, read straight from a public Solana RPC node — no key, nothing cached. Where EVM chains use 0x addresses, Solana uses base58 keys, and this reads them directly. The balance endpoint returns any wallet's SOL balance (in lamports and SOL) along with the account's program owner, whether it is executable and its rent epoch. The network endpoint returns the live state of the chain: the current epoch and how far through it the cluster is, the absolute slot and block height, the running transactions-per-second, the cumulative transaction count and the node health — Solana runs at thousands of transactions per second. The transactions endpoint returns a wallet's most recent transaction signatures with the slot, block time, success or failure and an explorer link. It reads Solana mainnet live. This is the account-and-network layer every Solana wallet, explorer, dashboard or dapp needs. Live from the chain, nothing stored. Distinct from EVM balance, token and transaction APIs — this is Solana on-chain data. 4 endpoints.

Live data for the Hive blockchain social network, served straight from Hive's public JSON-RPC nodes — no key, no account, nothing cached. Hive is a decentralised blogging and social platform where posts and votes live on-chain and earn crypto rewards. The account endpoint resolves a username to its profile: display name, reputation score, follower and following counts, post count, bio, location, website and join date — @gtg ("Gandalf the Grey") has a 76 reputation and over ten thousand followers. The posts endpoint returns a user's blog posts with each post's up-vote count, the HBD payout it earned, the comment count, the tags and a link. The trending endpoint returns the platform's trending (or hot, new or top-paid) posts right now, optionally filtered by tag — the front page of Hive. This is the profile-posts-and-trends layer for any decentralised-social, blogging or web3 app. Live from the Hive blockchain, nothing stored. Distinct from other social and centralised-blog APIs — this is the on-chain Hive network. 4 endpoints.

Live blockchain transaction, receipt and block lookup, read straight from the chain's public JSON-RPC node — no key, nothing cached. Give it a transaction hash and the transaction endpoint returns the full picture: the sender and recipient, the value moved (in wei and human ETH), the gas limit and gas price, the nonce, the block it landed in, the input-data size, and — by also reading the receipt — whether it succeeded or failed, the gas actually used, the effective gas price, the fee paid in ETH, the number of event logs it emitted, any contract it created and how many confirmations it now has. The receipt endpoint returns just the execution result (status, gas used, logs, contract address). The block endpoint takes a block number or "latest" and returns its timestamp, transaction count, gas used and limit with utilisation, base fee and miner. It works across seven EVM chains — Ethereum, Polygon, BNB Smart Chain, Arbitrum, Optimism, Base and Avalanche — with friendly aliases (eth, matic, bnb, arb, op, avax). This is the explorer-grade transaction layer every wallet, payment processor, dapp and dashboard needs to confirm and inspect on-chain activity. Read live from the chain, nothing stored. Distinct from balance, token-metadata and name-resolution APIs — this is transaction, receipt and block data read directly from the blockchain. 4 endpoints across 7 chains.

Live ERC-20 token metadata, read straight off the blockchain. Give it any token contract address and it returns the token's name, symbol, decimals and total supply — both as the raw on-chain integer and as a human-formatted number — by calling the ERC-20 contract directly via the chain's public JSON-RPC node (eth_call), confirming first that the address is really a contract. The USD Coin contract resolves to "USD Coin", symbol USDC, 6 decimals; Wrapped BTC on Polygon to "(PoS) Wrapped BTC", symbol WBTC, 8 decimals. The balance endpoint reads any wallet's holding of any token — pass the token contract and an owner address and it returns the balance raw and formatted with the token's own decimals and symbol. It works across seven EVM chains — Ethereum, Polygon, BNB Smart Chain, Arbitrum, Optimism, Base and Avalanche — with friendly aliases (eth, matic, bnb, arb, op, avax). This is the token-metadata and token-balance layer every wallet, DEX, portfolio tracker, block explorer and DeFi dashboard needs: turn a bare 0x… contract into a named, decimalled token, and resolve any holder's balance, in one call. Read live from the chain, no key on the data source, nothing cached. Distinct from native-coin balance and market-price APIs — this is on-chain ERC-20 contract data read directly from the blockchain. 4 endpoints across 7 chains.

Live DeFi total-value-locked per blockchain as an API, streamed from the DefiLlama chains feed. For every chain DefiLlama tracks: the dollar value of assets locked in its DeFi protocols, its native token symbol, and its share of all DeFi value (dominance), plus 7-day and 30-day change for a chain. Rank the blockchains by how much capital they hold, drill into one chain, read the total DeFi market and its leader, or search. The blockchain-level view of where DeFi capital lives. Live, no key. Distinct from protocol-level TVL, fees, DEX-volume and yield APIs — here the entity is the chain, not the protocol.
