The specific route `/api/v1/wire/106` is listed as \"Premium API Access\" and accepts POST requests. Payment is settled on the Base network using USDC (contract 0x8335…2913) 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 wide catalog of endpoints spanning data & analytics (metrics, reports, data export, insights), AI & machine learning (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 priced uniformly at $0.02 per request.\n\nHowever, the specific functionality behind `/api/v1/wire/106` is not documented beyond the generic label \"Premium API Access.\" The crawled docs, pricing, API, and README pages all returned only a \"Connect wallet\" prompt with no additional technical documentation, input/output schemas, or usage examples. Without knowing what data or service this particular endpoint returns, callers should treat it as an opaque paid endpoint until further documentation is available.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","post-endpoint"],"categories":["api-gateway","infrastructure"],"synonyms":["lowpaymentfee","low payment fee API","x402 premium API","pay-per-call API","USDC API access","Base network API"],"warnings":["The specific functionality of /api/v1/wire/106 is completely undocumented — it is unclear what data or service it provides.","All documentation pages (docs, pricing, README, api) returned only a 'Connect wallet' prompt with no usable content.","No input or output schema is available; callers cannot know what request body to send or what response to expect.","The endpoint label 'Premium API Access' is generic and does not describe a concrete capability."],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/106","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/106","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming pricing and payment details.
