The provider operates a broad suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network. No API keys, rate limits, or upfront commitments are required; callers simply attach an x402 payment header to each request.\n\nThe specific endpoint probed returns a 402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using the \"exact\" scheme with a 300-second timeout. The response MIME type is `application/json`. The endpoint accepts HTTP POST and is marked as discoverable.\n\nDocumentation beyond the landing page is extremely thin — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The actual content returned after successful payment (i.e., what a \"transaction receipt\" contains) is not documented anywhere in the crawled material.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","transaction-receipt","json-response","no-api-key","micropayment"],"categories":["finance","infrastructure"],"synonyms":["transaction receipt API","x402 micropayment","USDC pay-per-call","Base network API","lowpaymentfee","crypto payment API","402 payment required"],"warnings":["No OpenAPI or schema documentation available; /docs, /api, /pricing, /README pages are all blank beyond a wallet-connect prompt","The specific endpoint /api/v1/transactions/345/receipt is not listed among the provider's advertised APIs on the landing page","No request body schema or response schema is documented — callers cannot know what to send or what they will receive","The hardcoded transaction ID '345' in the path suggests this may be a demo or placeholder resource"],"endpointUrl":"https://lowpaymentfee.com/api/v1/transactions/345/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/345/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 and returns a valid x402 402 challenge with clear pricing.

The specific resource path (/transactions/345/receipt) is not listed on the homepage and its purpose is only inferable from the URL. This is effectively a stub
