Currency conversion API for AI agents — convert an amount between currencies using official ECB reference-rate data; one-shot x402 call with optional volume credits.

Convert between crypto and fiat at live rates: BTC, ETH, SOL, USDC and hundreds more against USD, GBP, EUR and 150+ currencies, either way, or crypto to crypto. Pass ?amount=0.5&from=BTC&to=GBP. Rate from Coinbase, cross-checked against Kraken's last trade where Kraken lists the pair, with the gap shown.

The busiest decentralised exchanges: DEXs ranked by trading volume over 24 hours, 7 days or 30 days, across all chains or on one chain (e.g. Base, Solana, Arbitrum), with each one's share of the total, day-on-day change and number of chains. Up to 50 rows. DefiLlama data.

Every perpetual futures market on Hyperliquid and dYdX side by side: which venues list each coin, price, open interest, 24h volume, max leverage and funding (hourly and APR) on each, plus the cross-venue funding spread and where longs pay least. Pass ?sort=fundingSpread&limit=20 for arbitrage candidates, or ?coin=SOL for one coin.

Perpetual futures funding rates from Hyperliquid and dYdX: the current hourly rate, 8-hour and annualised equivalents, premium, mark and oracle price and open interest per market, plus up to 7 days of hourly funding history and averages for one coin. Pass ?coin=BTC&hours=24 (&venue=dydx), or no coin for the top markets by open interest.

Which crypto protocols earn the most: a ranking by fees paid by users or by the protocol's own revenue over 24 hours, 7 days or 30 days, optionally for one chain (e.g. Base, Solana) or one category (Dexs, Lending, Stablecoin Issuer, Derivatives...). Up to 50 rows with amount, day-on-day change and number of chains. DefiLlama data.

Live order book for a perpetual futures market on Hyperliquid or dYdX: best bid and ask, spread in bps, USD depth within 10/50/100 bps of mid, and the average fill price and slippage of a market buy and sell of your size. Pass ?coin=ETH&sizeUsd=25000 (&venue=dydx).

OHLCV candles for a perpetual futures market on Hyperliquid or dYdX (1m to 1d, up to 500), with a summary: change, high/low, USD volume and annualised realised volatility. Pass ?coin=ETH&interval=1h&limit=24 (&venue=dydx).

Open interest on Hyperliquid or dYdX perpetual futures: contracts and USD value per market, share of the venue total, 24h volume, volume/OI, 24h price change and the current funding rate, plus venue totals. Pass ?coin=ETH for one market, or ?limit=20 for the largest markets by open interest; &venue=dydx for dYdX.

Live network fees on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche, Solana and Bitcoin: slow/standard/fast fee rates, congestion and trend, and the USD cost of a send, token transfer and swap on each, plus the cheapest chain now. Pick chains with chains (e.g. base,solana); all by default.

US macro indicators (CPI, core CPI, unemployment, Fed funds, GDP, 10y/2y yields, M2) with latest value + YoY + recent history, via FRED. ?series=cpi. Public-domain data, 6h cache. Never charged on failure.

Whole-market snapshot, already flattened to the numbers an agent usually needs: total market cap, 24h volume, BTC and ETH dominance, active cryptocurrencies and markets, 24h market cap change. One call instead of parsing a deeply nested payload.

Spot price in USD for up to 20 tokens identified by contract address, on Base, Ethereum, Arbitrum, Optimism or Polygon, with decimals and confidence. No API key, no rate limit surprises: useful to value a wallet, a treasury or an invoice in tokens that an exchange price endpoint cannot resolve.

24h statistics for up to 10 symbols: last price, price change and percent, weighted average, high, low, base volume and quote volume. Flattened from the exchange payload so the numbers are ready to compare or store.

Time series of price, market cap and total volume for one coin over 1 to 365 days, at the resolution CoinGecko serves (hourly up to 90 days, daily beyond). For charting, backtesting a strategy or computing volatility.
