The specific resource at `/api/v1/generate/resource/61` is listed as \"Premium API Access\" but its exact functionality is not documented beyond that label.\n\nPayment is handled via the x402 protocol on the Base network using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The maximum amount required per call is 20,000 base units of USDC, which at 6 decimals equals $0.02 USD — consistent with the site's advertised flat pricing of $0.02 per request. The endpoint accepts POST requests and returns `application/json`. No API keys or rate limits are advertised; access is gated purely by the x402 payment header.\n\nDocumentation is extremely sparse. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what data or functionality this specific resource provides. The endpoint is confirmed live (returns a proper 402 challenge), but without knowing what `resource/61` actually does, callers will need to experiment or contact the provider for details.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","json-api","no-api-key","post-method"],"categories":["infrastructure","api-gateway"],"synonyms":["lowpaymentfee","x402 API","USDC micropayment API","pay-per-call API","Base network API","crypto-gated endpoint"],"warnings":["The exact functionality of /api/v1/generate/resource/61 ('Premium API Access') is undocumented — it is unclear what this endpoint actually returns.","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no usable content.","No OpenAPI spec, no request schema, and no response examples are available.","The platform lists many endpoints but none appear to have public documentation beyond a name and price."],"endpointUrl":"https://lowpaymentfee.com/api/v1/generate/resource/61","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/generate/resource/61","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
