The specific resource path `/api/v1/wire/96` is one of many endpoints offered by the provider, which hosts a broad catalog spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request.\n\nThe endpoint is live and returns a valid x402 challenge. Payment is settled on the Base network using USDC (contract 0x8335…2913) with an exact-scheme payment of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). There are no API keys required, no rate limits advertised, and access is instant once payment is included in the X-PAYMENT header. The timeout window is 300 seconds.\n\nHowever, the specific functionality behind `/api/v1/wire/96` is not documented on the provider's site — it does not appear in the listed API catalog. The crawled docs, pricing, and README pages all returned only a \"Connect wallet\" prompt with no additional content. Without documentation or an output schema describing what this particular endpoint returns, its exact purpose remains unclear. The provider's landing page lists other endpoints (metrics, reports, sentiment analysis, summarization, etc.) but this wire/96 path is not among them.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","no-api-key","no-rate-limit","http-post"],"categories":["api","infrastructure"],"synonyms":["x402 API","pay-per-call API","USDC micropayment API","Base network API","lowpaymentfee","wire API","crypto-paid endpoint"],"warnings":["The endpoint path /api/v1/wire/96 is not listed in the provider's public API catalog — its purpose is unclear.","Documentation pages (/docs, /pricing, /README, /api) returned no meaningful content beyond 'Connect wallet'.","No output schema or example responses are available for this endpoint.","The exact data or service returned by this endpoint cannot be verified from available materials."],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/96","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/wire/96","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, but the specific resource /api/v1/wire/96 is undocumented — it does not appear in the provider's listed API catalog.
