Live data for Limitless Exchange, the on-chain prediction market on Base, with no key. List the active markets with each market's title, live YES/NO implied-probability prices (0–1), traded volume, deadline and category tags; pull a single-market detail by slug; and get the full tag list. Prices are the live market-implied odds for each binary outcome, settled in USDC — distinct from Polymarket and Kalshi. Ideal for odds dashboards, event monitors and crypto-native sentiment analytics across 900+ live markets.

Live circulating supply, chain distribution and supply history for any stablecoin, keyless. For one stablecoin (USDT, USDC, DAI, USDe) get its total circulating supply, peg type and mechanism, price, 1d/7d/30d supply change and market dominance; the per-chain breakdown of where that supply actually lives; and the circulating-supply history over time, for the whole asset or a single chain. Search 370+ stablecoins to find an id. Live, nothing stored. The single-stablecoin supply layer for treasury, risk, research and dashboard apps — distinct from whole-ecosystem stablecoin feeds, this is one stablecoin in depth.

Where dollar stablecoin liquidity actually lives, read live and keyless from each blockchain. USDC and USDT are issued natively on many chains, and the split between them is one of the most-watched signals in the layer-2 wars: Ethereum mainnet still holds the bulk, but Base, Arbitrum and the other rollups have been pulling stablecoin supply across as activity migrates. This API reads the native USDC and USDT supply directly from the token contract on each chain — Ethereum, Base, Arbitrum, Optimism, Polygon and Avalanche — not a single chain and not an aggregator, so you see the real on-chain distribution. The stablecoin endpoint takes a symbol (USDC or USDT) and returns its supply on every tracked chain, ranked, each with its share of that stablecoin and the Ethereum-versus-rollup split. The chains endpoint ranks the chains by their total native stablecoin liquidity (USDC and USDT together) — which chain hosts the most dollars. The summary endpoint is the top-down view: total USDC, total USDT, the combined total, the USDT-to-USDC ratio, and Ethereum's dominance versus the share that has moved to the rollups. Because USDC and USDT are dollar-pegged and read at the token's own on-chain decimals (read live from each contract, never assumed), the supply equals the dollars of stablecoin on that chain; only natively-issued supply is counted (bridged and peg tokens are excluded). This is the stablecoin chain-distribution cut — distinct from the single-chain token feeds, the generic stablecoin-supply aggregators and the price feeds: it is specifically the cross-chain liquidity map. Amounts are in US dollars. No key, nothing stored beyond a short cache.
