Celo On-Chain API

healthy 4,987 Subscribers

Live Celo on-chain data as an API, built on the open Blockscout explorer. Celo (chain id 42220) is a mobile-first, carbon-negative Ethereum-compatible network; its native currency is CELO and it hosts native stablecoins such as cUSD and cEUR. Pull network stats (total blocks and transactions, CELO price, live gas), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its balance and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for Celo wallets, block explorers, gas trackers, DeFi and stablecoin dashboards and on-chain analytics.

Plasma API

Real-time on-chain data for Plasma (chain-id 9745) — the stablecoin-native EVM Layer-1 anchored to Bitcoin and purpose-built for high-volume, low-cost stablecoin (USD₮) payments. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native XPL balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Plasma JSON-RPC node — decoded from hex into plain decimals and human-readable XPL so you do not have to. Ideal for explorers, wallets, payment dashboards, gas estimators and analytics on the Plasma chain.

Stablecoin Supply API

Live circulating supply, chain distribution and supply history for any stablecoin, keyless. For one stablecoin (USDT, USDC, DAI, USDe) get its total circulating supply, peg type and mechanism, price, 1d/7d/30d supply change and market dominance; the per-chain breakdown of where that supply actually lives; and the circulating-supply history over time, for the whole asset or a single chain. Search 370+ stablecoins to find an id. Live, nothing stored. The single-stablecoin supply layer for treasury, risk, research and dashboard apps — distinct from whole-ecosystem stablecoin feeds, this is one stablecoin in depth.

Spark Protocol API

Live protocol metrics for Spark (the Sky / former MakerDAO ecosystem capital-allocation protocol), keyless. Both Spark products: SparkLend, the lending money-market with per-asset supply APY and TVL, and Spark Savings, the sUSDS / USDS / USDC / USDT savings products passing through the Sky Savings Rate — a savings-yield dimension other lending APIs do not have. Plus total value locked and per-chain TVL. One combined overview endpoint snapshots it all. Live, nothing stored. The Spark-metrics layer for DeFi dashboards, lending, savings, stablecoin and yield apps — distinct from pure lending protocols, this is Spark lending-plus-savings model specifically.

Liquity Protocol API

Live protocol metrics for Liquity, the original immutable decentralized borrowing protocol that issues the LUSD and BOLD stablecoins against ETH and liquid-staking-token collateral, keyless. Get the total collateral locked, the breakdown of which assets back the stablecoins (ETH, wstETH, rETH across Liquity v1 + v2), per-chain TVL, and the Liquity pools (stability pools / earning positions) with their APY. One combined overview endpoint snapshots it all. Live, nothing stored. The CDP / decentralized-stablecoin metrics layer for DeFi dashboards, stablecoin, risk and yield apps — distinct from DEX, lending, restaking and yield protocols, this is Liquity collateralized-debt model specifically.
