Bitcoin OHLCV candlestick data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides Bitcoin (BTC) OHLCV (Open, High, Low, Close, Volume) candlestick data, accessible through the x402 payment protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The endpoint accepts POST requests and returns JSON.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per call. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment on Base, and the server fulfills the request upon verification.
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., timeframe, date range). The OHLCV endpoint is not even listed on the provider's landing page — the landing page lists other crypto endpoints like /crypto/quotes and /crypto/gas but not /crypto/BTC/ohlcv. The endpoint is confirmed live (returns a valid 402 x402 challenge), but without documentation the exact request format and response shape must be guessed.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation, no request/response examples, and the specific endpoint is not even listed on the provider's landing page. Nearly all request parameters and response structure must be guessed.
