MKR 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 the MKR (Maker) cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all gated behind the x402 payment protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each request is paid individually at the time of the call.
The broader lowpaymentfee.com platform lists additional crypto endpoints (token quotes, gas estimates, price feeds, exchange rates) as well as AI/ML endpoints (sentiment analysis, summarization, classification, embeddings) and utility services (geocoding, validation, conversion). All share the same $0.02/request pricing model. Documentation beyond the landing page is sparse — the /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no further technical detail, so the exact request body schema and response format for this OHLCV endpoint are not documented in the crawled material.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no documented request schema, no response schema, no examples, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The actual data content and parameters are entirely unknown.
Warnings
- —No request body schema documented — the required POST body fields (e.g., timeframe, date range) are unknown.
- —No response schema or example response available; actual OHLCV format is unverified.
- —All documentation pages (/docs, /pricing, /README, /api) returned only 'Connect wallet' with no technical content.
- —The platform lists many diverse endpoints (AI, finance, utilities) all at the same price, which may indicate a generic template rather than deeply implemented services.
