The whole crypto market in one call.
Crypto market pulse returns breadth, volume, open interest, funding extremes, the day's gainers and losers and BTC and ETH at a glance - one request, $0.004, no API key. 23 more calls below cover perps, options, DeFi and stablecoins at $0.001 to $0.005 each.
Pay per request in USDC over x402 or MPP from any wallet. The first call answers 402 with the price; the paid retry returns the data. A call that fails is not charged on x402.
