BNB OHLCV candlestick data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for BNB (Binance Coin) via the x402 payment protocol. It is part of a broader suite of finance, crypto, AI, and utility APIs hosted at lowpaymentfee.com, all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge confirms the endpoint is live and accepts POST requests with an exact payment scheme. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per call. There is a 300-second payment timeout window.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. No request/response schema, parameter documentation, or example payloads are available from the crawled material. The endpoint path suggests it returns OHLCV data for BNB, but the exact request format (e.g., timeframe, date range parameters) and response structure are unknown.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is zero documentation on request parameters or response schema. Docs pages all return only a wallet-connect prompt. The endpoint's actual behavior must be entirely inferred from its URL path.

- —Docs, API, pricing, and README pages all render only 'Connect wallet' with no technical content
- —Exact POST body parameters (timeframe, date range, etc.) are unknown
- —Response format is completely undocumented — cannot confirm OHLCV fields or structure
