The specific path `/api/v1/stripe/charges/160` suggests it proxies or wraps Stripe charge-related functionality. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe provider, lowpaymentfee.com, hosts a broader catalog of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the `/api/v1/stripe/charges/160` endpoint actually returns or expects as input. The x402 challenge confirms the endpoint is live and accepts POST requests, but the actual functionality behind the paywall is unclear from available materials.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-charges","pay-per-request","no-api-key"],"categories":["finance","infrastructure"],"synonyms":["stripe charges API","payment processing API","x402 stripe","lowpaymentfee","USDC micropayment API","pay-per-call API","Base network API"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'","No OpenAPI or request/response schema provided; input format and output structure are unknown","The actual behavior of /api/v1/stripe/charges/160 is unclear — it may proxy Stripe or be a placeholder","Cannot verify what data or service is delivered after payment without paying"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/160","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/charges/160","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
