Decode a 32-byte event topic to its event signature
API · /ethsignatures-api
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.

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
Ein Live-, abfragbarer Index jedes Ethereum Improvement Proposal (EIP) und ERC-Token-Standards, schlüssellos direkt aus den kanonischen ethereum/EIPs- und ethereum/ERCs-Repositories gelesen. Schlagen Sie jeden Vorschlag nach Nummer nach, um seinen Titel, Status (Draft, Review, Last Call, Final, Living, Stagnant oder Withdrawn), Typ und Kategorie, Autoren, Erstellungsdatum, Anforderungen und Abstract zu erhalten; rufen Sie mehrere Vorschläge auf einmal ab; oder listen Sie den gesamten Katalog von über 1.500 EIPs und ERCs auf. Die Referenzschicht für Wallets, Block-Explorer, Dokumentationsseiten und Entwickler-Tools, die programmatisch auflösen müssen, "was ist EIP-1559" oder "ist ERC-4626 endgültig", anstatt eine Website zu scrapen. Immer aktuell – live aus den Quell-Repositories gelesen, leicht gecached.

Compound Protocol API
Live protocol metrics for Compound Finance, one of the original decentralized lending protocols, keyless. Get the total value locked across every chain Compound is deployed on, the per-asset markets across Compound v2 and v3 (Comet) with supply APY and TVL — including the v3 distinction where collateral assets back a single borrowable base asset and do not earn yield (earns_yield) — and protocol fees. One combined overview endpoint snapshots it all. Live, nothing stored. The Compound-metrics layer for DeFi dashboards, lending, yield and risk apps — distinct from other lending protocols, this is Compound own markets, v2 + v3, multi-chain.
