The specific path `/api/v1/stripe/charges/12` appears to be one of many endpoints offered by the lowpaymentfee.com platform, which advertises a broad catalog spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request.\n\nThe x402 challenge confirms the endpoint is live and accepts payment via the \"exact\" scheme on the Base network. The required asset is USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maxAmountRequired of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The endpoint accepts HTTP POST requests.\n\nHowever, the specific functionality of this particular endpoint (`/stripe/charges/12`) is unclear. The path suggests it may relate to Stripe charge operations, but no documentation, request schema, or response schema is available. The provider's landing page lists many other endpoints but does not specifically document this one. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no substantive content. Without input/output schemas or usage examples, agents will need to experiment to determine what this endpoint actually does.","tags":[],"capabilities":["x402-payment","usdc-payment","base-network","http-post","pay-per-request","stripe-charges"],"categories":["finance","infrastructure"],"synonyms":["stripe charges API","x402 payment endpoint","USDC micropayment API","lowpaymentfee","pay-per-call API","Base network API","crypto payment gateway"],"warnings":["No request or response schema available for this endpoint","The specific functionality of /api/v1/stripe/charges/12 is undocumented — the path is not listed on the provider's landing page","All documentation pages (docs, pricing, API, README) render only a 'Connect wallet' prompt with no content","The endpoint path suggests Stripe charge operations but this is unconfirmed"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/12","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/12","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation for this specific endpoint's functionality, no request/response schema, and the crawled docs pages are empty.
