Unit Zero Chain API

Live on-chain data for Unit Zero — an EVM Layer 1 for real-world assets and AI compute — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's UNIT0 balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in UNIT0, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in UNIT0, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

Plume API

Live Plume on-chain data via Blockscout. Plume is a real-world-asset (RWA) focused Ethereum L2; gas and balances are in PLUME. Network stats, gas prices, latest blocks, a block by height or hash, address detail with PLUME balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

Crypto Treasury API

Live data on the public companies that hold Bitcoin and Ethereum on their balance sheets, from the public CoinGecko feed. Rank every public company by how much of the coin it holds, with current and entry value, average entry price, country and share of total supply; get the aggregate corporate holdings, USD value and market-cap dominance; find a specific holder by name, ticker or country; and compare Bitcoin and Ethereum corporate treasuries side by side. The corporate crypto-treasury layer — distinct from price and exchange feeds: it answers who holds how much, and what they paid. Live, with a short 60-second upstream cache.

Across Bridge API

Live cross-chain bridge data from Across, one of the largest intent-based bridges, which moves USDC, ETH, WBTC and other assets between Ethereum and its rollups (Arbitrum, Base, Optimism, Polygon, zkSync, Linea, Blast, Scroll and more) using a relayer network and a single unified liquidity pool. The quote endpoint prices a bridge transfer — the relayer capital fee, gas fee, LP fee, total fee, the amount received and the estimated fill time. The routes endpoint lists every supported bridge route (origin chain, destination chain, token). The limits endpoint returns the min and max bridgeable amount for a route. The chains endpoint lists supported chains. Read live from Across, nothing stored. This is Across's own cross-chain bridge fee, route and fill-time layer — distinct from DEX, lending, staking and price feeds.
