OHLCV candlestick data for Loopring (LRC) via pay-per-request x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the Loopring (LRC) 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.
Each request costs $0.02 in USDC (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC on Base, which equals $0.02 given USDC's 6 decimals). There are no API keys, no rate limits, and no subscriptions — you simply attach an X-PAYMENT header with a valid x402 payment proof and receive the data. The endpoint accepts POST requests and returns application/json.
The broader lowpaymentfee.com platform hosts additional crypto endpoints (token quotes, gas estimates, exchange rates, price feeds) as well as AI inference endpoints (sentiment analysis, summarization, classification, embeddings) and utility services (geocoding, validation, conversion). All share the same $0.02-per-request pricing model and x402 payment flow on the Base L2 network.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation of request parameters (e.g., timeframe, date range), and no example response. The docs, pricing, and API pages all returned only 'Connect wallet' with no useful content. The actual response shape and supported query parameters must be inferred.
Warnings
- —No documentation available — docs, pricing, and API pages all render only a wallet-connect prompt with no technical content.
- —Request body schema and query parameters (timeframe, date range, etc.) are completely undocumented.
- —Response schema is unknown — no example response or outputSchema fields provided.
- —The platform hosts many diverse endpoints (AI, finance, utilities) all at $0.02; unclear how mature or well-maintained each individual endpoint is.
