The specific endpoint `/api/v1/trades/101` is listed as \"Premium API Access\" and accepts payment in USDC (contract 0x8335…) on Base. The x402 challenge shows a maxAmountRequired of 20,000 base units, which at 6 decimals for USDC equals $0.02 per request — consistent with the site's advertised flat pricing of $0.02/request across all endpoints.\n\nThe broader platform advertises four endpoint categories: Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure/Utilities (geocoding, validation, conversion, generation). All endpoints are listed at the same $0.02 price point.\n\nThe platform emphasizes simplicity: no API keys, no rate limits, no commitments, and instant access. Payment is handled entirely through the x402 protocol using USDC on the Base L2 network. Documentation pages (/docs, /pricing, /README) appear to require a wallet connection and returned no substantive content during the crawl, so detailed request/response schemas for the `/trades/101` endpoint are unknown. The endpoint accepts POST requests and returns application/json, but the specific payload structure is not documented in the available material.","tags":[],"capabilities":["x402-payment","usdc-on-base","per-request-billing","json-api","post-method","no-api-key","trade-data"],"categories":["finance","data"],"synonyms":["premium API access","trade data API","x402 API","pay-per-call API","Base network API","USDC micropayment API","lowpaymentfee"],"warnings":["No OpenAPI or request/response schema available for this endpoint","Documentation, pricing, and README pages all require wallet connection and returned no useful content","The specific data returned by /api/v1/trades/101 is undocumented — 'Premium API Access' is a generic label","Cannot verify what trade data (if any) this endpoint actually returns"],"endpointUrl":"https://lowpaymentfee.com/api/v1/trades/101","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/trades/101","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and documentation pages returned no content.
