All endpoints are priced at $0.02 per request, payable in USDC on the Base network with no API keys, no rate limits, and no commitments required. The x402 payment protocol allows agents and users to pay per call by attaching a cryptographic payment header to each HTTP request.\n\nThe specific endpoint at `/api/v1/wire/92` is listed as \"Premium API Access\" and returns a 402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site's advertised pricing. The endpoint accepts POST requests and returns application/json responses.\n\nThe broader platform advertises endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show \"Connect wallet\"), so the actual functionality behind each endpoint is unverified. Without OpenAPI schemas, request/response examples, or detailed docs, the precise inputs and outputs for this endpoint remain unknown.","tags":[],"capabilities":["x402-payment","per-call-pricing","usdc-base-network","http-post","json-response","no-api-key"],"categories":["api-platform","infrastructure"],"synonyms":["pay-per-call API","x402 API","micropayment API","USDC API access","Base network API","low fee API","crypto-paid API"],"warnings":["No documentation available — all doc, pricing, and API pages return only 'Connect wallet'","The purpose and functionality of /api/v1/wire/92 ('Premium API Access') is not described anywhere","No OpenAPI spec, no request/response schema, no examples provided by the provider","Cannot verify what data or service this endpoint actually returns"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/92","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/92","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 with clear pricing ($0.02 USDC on Base).
