The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics (metrics, reports, data export, insights), AI/ML (sentiment analysis, text summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request on the Base network. However, this specific listing covers only the `/api/v1/transactions/350/receipt` endpoint.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what the receipt object contains. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual response schema and data semantics are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","transaction-receipt","pay-per-call","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["transaction receipt API","x402 micropayment endpoint","Base USDC API","pay-per-request API","lowpaymentfee","crypto payment API","receipt lookup"],"warnings":["No documentation available — all doc pages render only 'Connect wallet'","No OpenAPI or output schema describing the receipt response format","This endpoint is scoped to a single transaction ID (350); unclear if other transaction IDs are supported at different paths","The platform lists many other endpoints but none have documented schemas or examples"],"endpointUrl":"https://lowpaymentfee.com/api/v1/transactions/350/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/350/receipt","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid x402 402 challenge, but documentation is essentially nonexistent — docs/pricing/API pages all show only 'Connect wallet'.
