The endpoint is labeled \"Premium API Access\" and accepts POST requests, returning application/json responses. Payment is handled via the x402 exact scheme on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).\n\nThe specific endpoint `/api/endpoint-93` does not correspond to any of the documented API paths listed on the provider's homepage (which use `/api/v1/` and `/api/v2/` prefixes). The crawled documentation, pricing, and README pages returned only a \"Connect wallet\" prompt with no additional content. As a result, the actual functionality behind this endpoint is unknown — the description \"Premium API Access\" is the only label provided, and no input/output schema, example payloads, or detailed documentation are available.\n\nThe x402 challenge is live and well-formed, confirming the endpoint is operational and accepting payment-gated requests. The maximum amount required is 20,000 units of USDC (likely 0.02 USDC given 6 decimals, consistent with the $0.02/request pricing shown on the homepage). No API keys or rate limits are advertised.","tags":[],"capabilities":["x402-payment","usdc-payment","base-network","pay-per-request","json-api","post-endpoint"],"categories":["api","payment-gated"],"synonyms":["premium API","x402 API","pay-per-call API","USDC gated endpoint","lowpaymentfee","micropayment API","Base network API"],"warnings":["Endpoint path /api/endpoint-93 does not match any documented API paths on the provider's homepage","No input or output schema available — actual functionality is unknown","Documentation pages (/docs, /pricing, /README) returned only 'Connect wallet' with no useful content","The label 'Premium API Access' is generic and does not describe what the endpoint does"],"endpointUrl":"https://lowpaymentfee.com/api/endpoint-93","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/endpoint-93","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and well-formed, but the endpoint path `/api/endpoint-93` doesn't match any documented API on the site.
