The endpoint is live and returns a standard 402 challenge requesting payment in USDC on the Base network. The price per call is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is sent to a specified wallet address, and no API keys or rate limits are required.\n\nThe broader lowpaymentfee.com platform advertises a suite of pay-per-call 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 priced at $0.02 per request. However, this specific listing covers the `/api/v1/stripe/charges/99` endpoint. The exact functionality behind this particular route is unclear from the available documentation; the path suggests it may relate to creating or retrieving Stripe charge objects, but no schema, example payloads, or detailed docs were found.\n\nDocumentation pages (/docs, /api, /pricing, /README) all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no usage examples available. The endpoint accepts POST requests and returns application/json according to the x402 challenge metadata.","tags":[],"capabilities":["x402-payment","usdc-base-network","pay-per-call","stripe-charges","no-api-key","no-rate-limits","json-response"],"categories":["finance","payments"],"synonyms":["stripe charge API","x402 payment endpoint","USDC micropayment API","pay-per-request API","Base network API","crypto payment gateway","lowpaymentfee"],"warnings":["No documentation available — all doc pages (/docs, /api, /pricing, /README) return only 'Connect wallet' with no content","No OpenAPI or request/response schema provided","The exact purpose of /api/v1/stripe/charges/99 is unclear — the path suggests Stripe charge operations but no details are confirmed","No example requests or responses available to verify functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/99","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/99","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 challenge with clear pricing ($0.02 USDC on Base).
