Pay-per-call Litecoin OHLCV candlestick data via x402 on Base (USDC).
What it does
This endpoint provides Litecoin (LTC) OHLCV (Open, High, Low, Close, Volume) candlestick data behind an x402 paywall. It is hosted on lowpaymentfee.com, a platform offering a broad catalog of pay-per-request APIs spanning data analytics, AI/ML, finance, and infrastructure — all settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (20,000 base units with 6 decimals) with no API keys, subscriptions, or rate limits required. Payment is made inline via the X-PAYMENT header per the x402 specification. The x402 challenge confirms the endpoint is live, advertising version 1 of the protocol with a 300-second payment timeout.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. The exact request body schema (e.g., how to specify time range, interval, or trading pair details) and the response schema (field names, data types) are not documented anywhere in the crawled material. Users will need to experiment or contact the provider to determine the expected input format.

Quality
The x402 challenge is live and confirms pricing and network details, but there is zero documentation on request/response schemas, supported parameters, or example payloads. The docs, API, pricing, and README pages are all blank beyond a wallet-connect prompt, making this effectively a stub listing.
Warnings
- —No request or response schema documented — input parameters are unknown
- —All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no content
- —Exact data coverage (time ranges, intervals, exchanges) is unspecified
- —Cannot verify actual data quality or source without making a paid request
