Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller simply includes an X-PAYMENT header with a valid x402 payment proof and receives the token price data in return.\n\nThe endpoint is part of a broader suite of APIs offered at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints on the platform follow the same $0.02-per-request pricing model settled in USDC on Base. The specific endpoint at `/api/v1/tokens/ETC/price` falls under the Finance & Web3 category, providing real-time cryptocurrency price information.\n\nThe x402 challenge confirms the endpoint is live, accepting POST requests, and settling payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on the Base network. The maximum payment required is 20,000 base units of USDC (6 decimals), which equals $0.02. No OpenAPI schema or detailed documentation was found beyond the landing page listing.","tags":[],"capabilities":["crypto-price-feed","etc-price","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","real-time-data"],"categories":["finance","crypto"],"synonyms":["Ethereum Classic price","ETC token price","ETC USD price","crypto price API","token price feed","ETC market data","cryptocurrency price endpoint"],"warnings":["No OpenAPI or JSON schema describing the response format is available.","Documentation pages (/docs, /pricing, /README) return no meaningful content — only a 'Connect wallet' prompt.","The exact response structure (fields, units, timestamp format) is not documented and must be discovered empirically.","The endpoint path suggests a single-token price endpoint; breadth of token coverage is unknown."],"endpointUrl":"https://lowpaymentfee.com/api/v1/tokens/ETC/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/ETC/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base).
