It is part of the lowpaymentfee.com platform, which offers a broad suite of data, analytics, AI, finance, and utility APIs — all gated behind the x402 payment protocol on the Base network.\n\nThe endpoint is live and returns a standard x402 402 challenge when called without payment. Each request costs $0.02 (20,000 base units of USDC on Base, which has 6 decimals). Payment is settled on-chain via USDC (contract 0x8335…2913) on Base to the provider's address. No API keys, rate limits, or subscriptions are required — callers simply attach an x402 payment header to each request.\n\nDocumentation beyond the landing page is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint accepts POST requests and returns application/json, but the exact request body format and response structure for OHLCV data must be inferred or discovered experimentally.","tags":[],"capabilities":["ohlcv-candlestick-data","crypto-market-data","sand-token","x402-payment","base-network","usdc-settlement","pay-per-request"],"categories":["finance","crypto"],"synonyms":["SAND OHLCV","SAND candlestick","The Sandbox price data","crypto OHLCV API","SAND market data","cryptocurrency candles","SAND historical price"],"warnings":["No OpenAPI or schema documentation available — request body format is unknown","All documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no content","Response schema for OHLCV data is entirely undocumented; callers must experiment to discover the format","Provider hosts many diverse API categories (AI, geocoding, finance, etc.) from a single domain with no visible documentation — exercise caution"],"endpointUrl":"https://lowpaymentfee.com/api/v1/crypto/SAND/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/SAND/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.
