OHLCV candlestick data for DYDX via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the DYDX cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a collection of pay-per-call APIs spanning data analytics, AI/ML, finance, and infrastructure utilities. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint at `/api/v1/crypto/DYDX/ohlcv` accepts POST requests and returns JSON. The x402 challenge advertises a maximum amount of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request. No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access.
Documentation beyond the landing page is sparse. The docs, API, pricing, and README pages all resolve to a minimal "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no description of request parameters (e.g., timeframe, date range), and no sample responses. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request body format and response structure must be discovered experimentally.

Quality
The endpoint is confirmed live via a valid 402 challenge and pricing is clear ($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 'Connect wallet' stub. The listing is effectively a stub with verified liveness.
