All endpoints are priced at $0.02 per request, settled in USDC on the Base network via the x402 protocol.\n\nThe specific endpoint at `/api/v1/wire/117` is listed as \"Premium API Access\" and returns a valid x402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02). Payment is made via the `exact` scheme with a 300-second timeout. No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available from the crawled content. The exact functionality behind the `/api/v1/wire/117` \"Premium API Access\" endpoint is unclear and may be a generic or catch-all route rather than a specific service.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","data-analytics","ai-inference","sentiment-analysis","text-summarization","classification","embeddings","finance-data","geocoding","utility-apis"],"categories":["ai","data","finance","infrastructure"],"synonyms":["low payment fee","x402 api","pay per call api","usdc api","base network api","micropayment api","402 payment api"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all render only 'Connect wallet'","No OpenAPI or schema definitions found for any endpoint","The specific functionality of /api/v1/wire/117 ('Premium API Access') is unclear and may be a generic or placeholder route","No request or response examples available to verify actual endpoint behavior"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wire/117","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/117","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 challenge with clear pricing ($0.02 USDC on Base).
