#supply

Live Bitcoin on-chain economics and network-activity statistics, built on the open blockchain.com dataset — the macro on-chain layer, not raw address or mempool lookups: a live network snapshot (24h transaction count and USD volume, hash rate, market price and cap, total mined supply, miners' revenue), the historical time series of any curated on-chain metric (active addresses, transaction volume, UTXO-set size, mempool size, miner revenue, fees and more), the catalog of available metrics, and Bitcoin's issuance state (total mined, share of the 21M cap, current block reward and estimated next halving).

Live Bitcoin halving countdown and supply schedule as an API, computed from the on-chain block height (mempool.space). Bitcoin's block subsidy halves every 210,000 blocks (~four years); this returns the current subsidy in BTC, the halving epoch, the next halving's block height, how many blocks and roughly how long remain (using the network's recent average block time), and the estimated date. It also computes the circulating supply mined to date from the issuance schedule, the percent of the 21-million cap already mined, the daily and annual new issuance and the inflation rate, plus the full halving schedule. The Bitcoin issuance-and-halving layer for crypto, dashboard and countdown apps. Live, no key, no cache. Distinct from fee and mempool Bitcoin APIs — this is the supply and halving schedule.

Live crypto tokenomics — supply and dilution metrics for any cryptocurrency, powered by CoinGecko. For any coin it returns the circulating, total and maximum supply, the percentage of the maximum supply already issued, the market cap and the fully-diluted valuation (FDV), and the market-cap-to-FDV ratio — the share of supply already unlocked — together with the dilution overhang, the percentage of FDV still locked or yet to be minted. It can also rank the top coins by dilution overhang (which assets have the most future supply hanging over them) or by how much of their cap is issued. The supply-and-dilution layer that token research, due diligence and risk dashboards need. Live, no key, no cache. Distinct from price, market-cap and all-time-high APIs — this is the tokenomics analytic.

Live stablecoin supply, peg and dominance data across the whole crypto ecosystem as an API, streamed from the DefiLlama stablecoins feed. For every tracked stablecoin: its circulating supply in USD, current price and peg deviation, peg type and mechanism (fiat-backed, crypto-backed or algorithmic), the chains it lives on, and its share of the total stablecoin market. List the biggest stablecoins with their dominance, drill into one for its peg health and per-chain breakdown, see total stablecoin supply per chain, or search. Built for crypto, risk and dashboard apps. Live, no key. Distinct from TVL, price and yield APIs — this is the stablecoin supply and peg surface.
