It is part of the lowpaymentfee.com platform, which offers a broad suite of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint at `/api/v1/tokens/SAND/price` accepts POST requests and returns JSON. Each call costs $0.02 in USDC (maxAmountRequired of 20,000 base units with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — you pay per request using an x402 payment header. The platform advertises instant access and a uniform $0.02/request pricing model across all its endpoints.\n\nDocumentation beyond the landing page is sparse; the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec or detailed response schema available. The endpoint is confirmed live, returning a proper 402 challenge when called without payment.","tags":[],"capabilities":["token-price-lookup","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","json-response"],"categories":["finance","crypto"],"synonyms":["SAND token price","Sandbox price API","crypto price feed","token price endpoint","SAND market data","cryptocurrency price lookup","Web3 price API"],"warnings":["No API documentation available — /docs, /api, /pricing, and /README all show only a wallet connect prompt","No response schema or example response provided; the shape of the returned price data is unknown","The endpoint path suggests a single-token price lookup for SAND, but no confirmation of response fields exists","No SLA, uptime guarantees, or rate limit details documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/SAND/price","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/tokens/SAND/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02/request in USDC on Base).
