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.\n\nThe 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.\n\nDocumentation 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.","tags":[],"capabilities":["ohlcv-candlestick-data","litecoin-market-data","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","json-response"],"categories":["finance","crypto"],"synonyms":["LTC OHLCV","Litecoin candlestick","Litecoin price history","crypto OHLCV API","LTC market data","Litecoin open high low close volume"],"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"],"endpointUrl":"https://lowpaymentfee.com/api/v1/crypto/LTC/ohlcv","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/crypto/LTC/ohlcv","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"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.
