It is part of a broader platform offering dozens of pay-per-call APIs spanning data & analytics, AI/ML inference, finance & Web3 data, and infrastructure utilities — all priced at $0.02 per request settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/stripe/charges/153` sits under the Stripe charges path, suggesting it returns or processes information related to a Stripe charge object (charge ID 153). However, no detailed documentation, request schema, or response schema is available — the docs, API, pricing, and README pages all resolve to a minimal \"Connect wallet\" prompt with no further content. The x402 challenge confirms the endpoint is live: it returns a 402 with an `exact` payment scheme requiring up to 20,000 base units of USDC (0x8335… on Base), which equals $0.02 given USDC's 6 decimals.\n\nThe platform advertises no API keys, no rate limits, and instant access. Payment is made via the x402 protocol's X-PAYMENT header. The payTo address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. Because the endpoint path references Stripe charges, it likely wraps or proxies Stripe payment data, but the exact request/response format is undocumented.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","stripe-charges","no-api-key","no-rate-limit"],"categories":["finance","infrastructure"],"synonyms":["stripe charge lookup","payment data API","x402 API","USDC micropayment","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No request or response schema available — the exact payload format is unknown.","Documentation pages (/docs, /api, /pricing, /README) all render only a 'Connect wallet' prompt with no useful content.","The endpoint path '/api/v1/stripe/charges/153' references a hardcoded charge ID (153); it is unclear whether this is a generic endpoint or specific to one charge.","The platform lists many API categories (AI, analytics, finance, etc.) but none have visible documentation — treat all claims with caution."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/153","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/153","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
