It is one of many endpoints on the platform, which offers data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities—all priced at $0.02 per request with no API keys, no rate limits, and no commitments.\n\nThe specific endpoint `/api/v1/transactions/47/receipt` returns a JSON response upon payment of 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base network, which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme by including an X-PAYMENT header in a POST request. The payment is directed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a maximum timeout of 300 seconds.\n\nThe broader platform advertises categories including metrics, reports, data export, insights, sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation endpoints. Documentation pages exist but appear to require wallet connection and contain no further technical detail in the crawled content.","tags":[],"capabilities":["x402-payment","usdc-base-network","pay-per-request","transaction-receipt","json-response","no-api-key","no-rate-limit"],"categories":["finance","infrastructure"],"synonyms":["transaction receipt API","x402 payment endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No OpenAPI or detailed documentation available—docs pages only show 'Connect wallet'","The specific resource '/api/v1/transactions/47/receipt' purpose is unclear; 'Premium API Access' is a generic description","No response schema or example responses are available","The broader platform lists many endpoints but none have documented input/output schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/transactions/47/receipt","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/transactions/47/receipt","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear, but there is no OpenAPI schema, no response examples, no documentation beyond a wallet-connect prompt, and the specific purpose of 'transactions/47/receipt' is unclear.
