It is part of the lowpaymentfee.com platform, which offers a suite of data, analytics, AI, finance, and utility APIs all priced at $0.02 per request using the x402 payment protocol.\n\nThe endpoint is accessed via HTTP POST and is gated by an x402 payment challenge. Payment is settled in USDC on the Base network. The max amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys or accounts are needed — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access.\n\nDocumentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no documentation of query parameters (e.g., timeframe, date range, or exchange). The OHLCV data format and supported parameters must be inferred from the endpoint path alone. Callers should expect a JSON response containing typical OHLCV fields but should be prepared for undocumented structure.","tags":[],"capabilities":["ohlcv-candlestick-data","mina-token","crypto-market-data","x402-micropayment","usdc-base-settlement","no-api-key","per-request-pricing"],"categories":["finance","crypto"],"synonyms":["MINA price data","MINA candlestick","MINA OHLCV","crypto OHLCV API","MINA market data","cryptocurrency candles","MINA token chart data"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all return only 'Connect wallet' with no content.","No OpenAPI or JSON schema describing request parameters (timeframe, date range, exchange, etc.) or response format.","Response structure for OHLCV data is entirely undocumented and must be discovered empirically.","The specific MINA/ohlcv endpoint is not listed on the landing page's API catalog, though similar crypto endpoints are."],"endpointUrl":"https://lowpaymentfee.com/api/v1/crypto/MINA/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/MINA/ohlcv","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base).
