OHLCV candlestick data for MASK token, paid per-request via x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the MASK token (Mask Network). It is part of the lowpaymentfee.com platform, which offers a broad suite of pay-per-request APIs spanning crypto market data, finance, AI/ML inference, analytics, and utilities. All endpoints use the x402 payment protocol on the Base network, settling in USDC.
The specific endpoint at `/api/v1/crypto/MASK/ohlcv` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…on Base), which equals $0.02 per request given USDC's 6 decimals. The platform advertises no API keys, no rate limits, and instant access — you simply attach an x402 payment header to each call.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of accepted parameters (e.g., time interval, date range) or response fields. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is difficult to know exactly what parameters to send or what shape the response takes.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documentation of request parameters or response format, and all doc pages return only a wallet-connect stub. The listing is essentially a stub with pricing info.
