Live economic-activity metrics for Ethereum Layer-2 rollups — Arbitrum, Base, Optimism, zkSync, Linea, Scroll, Polygon and more — powered by the public growthepie.xyz feed, no key, nothing stored. This is the L2 fundamentals cut: not a single chain's block or gas data, but how much each rollup is actually used and what it earns. The chains endpoint lists the tracked rollups. The chain endpoint returns one rollup's latest metrics: daily active addresses, transaction count, fees paid, on-chain profit (the fees it keeps after paying Ethereum to post its data), median transaction cost, stablecoin supply, total value locked, market cap and fully-diluted valuation. The metric endpoint ranks every rollup by a single metric, so you can see at a glance which L2 leads on users, fees or profit and how the scaling race is shifting. Track the real adoption and economics of the rollup ecosystem as live JSON. This is the L2 activity / economics cut — distinct from the per-chain on-chain (block and gas) APIs and the TVL-only APIs in the catalogue.

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.
