OHLCV candlestick data for COMP (Compound) via pay-per-request x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the COMP (Compound) token. It is part of the lowpaymentfee.com platform, which offers a broad suite 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.
Each request costs $0.02 in USDC (the x402 challenge advertises a maxAmountRequired of 20000 base units against the USDC contract on Base, which at 6 decimals equals $0.02). There are no API keys, no rate limits, and no subscriptions — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The endpoint accepts POST requests and returns JSON.
Documentation beyond the landing page is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. No OpenAPI schema, request/response examples, or parameter documentation were found. The exact request body format (e.g., how to specify timeframe, date range, or granularity for OHLCV data) is unknown and must be discovered experimentally.
