Payment is settled on the Base network using USDC (contract 0x8335…2913) with an exact-scheme challenge. The max amount required is 20,000 base units, which at 6 decimals equals $0.02 per call.\n\nThe broader lowpaymentfee.com platform advertises a suite of pay-per-request APIs spanning 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 $0.02 per request with no API keys, no rate limits, and no minimum commitments.\n\nThe specific endpoint probed (/api/v1/stripe/customers/33) is labeled \"Premium API Access\" and returns a valid x402 challenge (HTTP 402). However, documentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no examples of what this Stripe customer endpoint actually returns. The purpose of exposing a Stripe customer record behind a paywall is unclear and should be verified before use.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-customer-data","pay-per-request","no-api-key"],"categories":["finance","infrastructure"],"synonyms":["stripe customer API","x402 paid API","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No API documentation available — /docs, /api, /pricing, and /README all render only a wallet-connect prompt","No OpenAPI or schema definition found for any endpoint","The purpose of exposing a Stripe customer record (customer 33) behind a paywall is unclear and potentially sensitive","No response schema or example responses available to verify what data is returned","The platform lists many endpoints on its homepage but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/customers/33","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/stripe/customers/33","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, but documentation is essentially nonexistent — all doc pages show only 'Connect wallet'.
