Gnosis Chain On-Chain API

healthy 4,963 Subscribers

Live Gnosis Chain on-chain data as an API, built on the open Blockscout explorer. Gnosis Chain (chain id 100, formerly xDAI) is a long-running Ethereum-compatible network whose native currency is the xDAI stable token, so gas and balances are denominated in a dollar-pegged coin. Pull network stats (total blocks and transactions, native 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 Gnosis wallets, block explorers, gas trackers, DeFi dashboards and on-chain analytics.

Blockchair Multi-Chain Stats API

Live on-chain network statistics, mempool conditions and market data across the major UTXO blockchains and Ethereum, sourced from Blockchair. For any supported chain read the full network state — best block height, total and 24-hour block and transaction counts, mining difficulty, hashrate, coin circulation, on-chain transfer volume and chain size — or zoom into the mempool to see pending transactions, mempool size, transactions-per-second, the suggested fee per byte (or median gas price on Ethereum) and average and median transaction fees in native units and USD, or pull market data with the coin price in USD and BTC, 24-hour change, market capitalisation and dominance. Ten chains are covered: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash, Bitcoin SV, eCash, Groestlcoin and Ethereum. Distinct from single-chain mempool and gas feeds: this is one consistent multi-chain stats surface.

DexPaprika On-Chain DEX API

Live on-chain decentralized-exchange market data across 35+ blockchains, with no key. List every supported network with its 24h DEX volume, transaction count and pool count; read the DEXes active on any chain; pull the top liquidity pools ranked by volume; get full token detail with multi-window price stats; search across every chain for tokens, pools and DEXes; and read global coverage totals. The on-chain / DEX / liquidity-pool layer for DeFi dashboards, token analytics, trading and research — distinct from centralized-exchange ticker readers. Live from DexPaprika (by the CoinPaprika team); short cache only.

EIP Registry API

A live, queryable index of every Ethereum Improvement Proposal (EIP) and ERC token standard, read keyless straight from the canonical ethereum/EIPs and ethereum/ERCs repositories. Look up any proposal by number for its title, status (Draft, Review, Last Call, Final, Living, Stagnant or Withdrawn), type and category, authors, creation date, what it requires and its abstract; pull several proposals at once; or list the whole catalog of 1,500+ EIPs and ERCs. The reference layer for wallets, block explorers, documentation sites and developer tooling that need to resolve "what is EIP-1559" or "is ERC-4626 final yet" programmatically instead of scraping a website. Always current — read live from the source repos, lightly cached.

Ethereum Signatures API

Decode Ethereum smart-contract function and event signatures, keyless. Turn a 4-byte function selector (the first 4 bytes of any transaction calldata, e.g. 0xa9059cbb) into its human-readable function signature (transfer(address,uint256)), decode a 32-byte event topic from a log into its event signature, or search the database by name to find a selector. Many selectors have hash collisions — the API flags the original / canonical signature. Backed by the open 4byte.directory database, live. Essential for transaction decoders, block explorers, wallets, security tools and on-chain analytics — the signature-decoding layer for any EVM tooling.
