The specific path `/api/v1/stripe/charges/128` appears to be one of many endpoints offered by the provider, which hosts a broad catalog spanning data & analytics, AI/ML inference, finance & Web3 data, and infrastructure utilities — all priced at $0.02 per request.\n\nPayment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 exact-payment scheme. The maximum amount required is 20,000 base units, which at 6 decimals equals $0.02 USD. No API keys or rate limits are advertised; callers simply attach an X-PAYMENT header with a valid x402 payment proof. The endpoint accepts POST requests and returns application/json.\n\nDocumentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. The specific functionality behind the `/api/v1/stripe/charges/128` path is not documented; the name \"Premium API Access\" and the path segment \"stripe/charges\" suggest it may proxy or wrap Stripe charge creation, but this is unconfirmed. Without request/response schemas or usage examples, callers will need to experiment to determine the expected input and output formats.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","stripe-charges","json-api","no-api-key"],"categories":["finance","infrastructure"],"synonyms":["stripe charge API","x402 payment endpoint","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No documentation available — all doc/API/pricing/README pages show only 'Connect wallet'","No request or response schema provided; input/output format is unknown","The specific functionality of /api/v1/stripe/charges/128 is undocumented and unclear","The endpoint name 'Premium API Access' is generic and does not describe actual functionality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/128","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/128","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 captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on what the endpoint actually does, no request/response schema, and all doc pages render only 'Connect wallet'.
