Ethereum Supply & Burn API

3,842 Subscribers
Live Ethereum monetary-policy data — the total ETH supply, how much of it is being created versus destroyed, and the EIP-1559 fee burn that can make ether deflationary (the "ultrasound money" thesis), powered by the public ultrasound.money feed, no key, nothing stored. The supply endpoint returns the current circulating ETH supply and its net change over the last 5 minutes, hour, day, week and month — a negative change means more ETH was burned than issued, i.e. net deflation. The burn endpoint returns the ETH destroyed by the base-fee burn over each window in both ETH and USD, the live burn rate in ETH per minute and the current deflationary streak. The basefee endpoint returns the current base fee per gas, the blob base fee and the ETH price. The leaderboard endpoint ranks the apps and contracts burning the most ETH right now. Track ETH issuance, the burn and whether ether is deflating as live JSON. This is the ETH supply / issuance / burn cut — distinct from the gas-fee, on-chain and price 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.
