Monero (XMR) OHLCV candlestick data via x402 micropayment at $0.02 per request on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for Monero (XMR) cryptocurrency. It is part of the lowpaymentfee.com platform, which offers a variety of data, AI, finance, and utility APIs all priced at $0.02 per request and payable via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and is gated by an x402 payment challenge. The maximum amount required per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimal places. Payment is settled on-chain to the provider's address. No API keys, rate limits, or upfront commitments are required — each request is independently paid for at the time of the call.
Documentation beyond the landing page is sparse. The /docs, /pricing, and /README pages all resolve to a minimal "Connect wallet" prompt with no additional technical detail. The exact request body schema (e.g., parameters for time range, interval, or exchange) and the response schema (field names, data types) are not documented in any crawled material. The endpoint is confirmed live via a valid 402 challenge response.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no documented request schema, no response schema, no examples, and all documentation pages return only a 'Connect wallet' stub. The actual data content and parameters must be guessed.
