OHLCV candlestick data for BLUR token, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) market data for the BLUR cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all payable per-request using the x402 protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is individually paid via the X-PAYMENT header. The x402 challenge was confirmed live, returning a standard 402 Payment Required response.
Documentation beyond the landing page is sparse. The docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. No OpenAPI schema, request/response examples, or parameter documentation were found. The exact request body format (e.g., timeframe, date range, limit parameters) and response structure are unknown and must be inferred or discovered experimentally.
