OHLCV candlestick data for KAVA cryptocurrency, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the KAVA token. It is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-call APIs spanning crypto market data, finance, AI/ML inference, analytics, and utilities — all gated via the x402 payment protocol on the Base network.
The endpoint is live and returns a standard x402 402 challenge when called without payment. It accepts POST requests and charges $0.02 per call, settled in USDC (contract 0x8335…2913) on Base. The x402 challenge specifies a maxAmountRequired of 20,000 base units; since USDC uses 6 decimals, this equals $0.02. No API keys or rate limits are advertised — access is purely payment-gated.
Documentation beyond the landing page is extremely thin: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact request body format (e.g., time range, interval, pagination) and the structure of the OHLCV response are unknown and must be discovered experimentally.
