The site hosts a broad catalog of pay-per-request APIs spanning data & analytics, AI/ML inference, finance & Web3 data, and infrastructure utilities — all priced at $0.02 per request, settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/wire/166` is listed as \"Premium API Access\" with a maximum cost of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). It accepts HTTP POST requests and returns application/json. Payment is handled via the x402 exact-payment scheme: callers attach an X-PAYMENT header with a signed payment to the payTo address. No API keys, rate limits, or upfront commitments are required — access is instant once payment is included.\n\nDocumentation on the site is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI spec, no request/response schema documentation, and no examples for what `/api/v1/wire/166` actually returns. The endpoint is confirmed live (returns 402 challenge correctly), but without documentation it is unclear what data or functionality \"Premium API Access\" specifically provides. The site's landing page groups endpoints into categories (analytics, AI, finance, utilities) but this particular wire/166 path does not appear in any of those listed categories.","tags":[],"capabilities":["x402-payment","usdc-base-network","pay-per-request","json-response","no-api-key","http-post"],"categories":["api-marketplace","crypto"],"synonyms":["lowpaymentfee","x402 api","pay per call api","usdc api access","base network api","micropayment api","premium api"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'","No OpenAPI or schema definition for this endpoint","The path /api/v1/wire/166 does not appear in the site's listed API catalog — its specific functionality is unknown","No request body schema or response examples available"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/166","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/166","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 challenge, confirming pricing and payment details.
