It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all gated via the x402 payment protocol on the Base network, settling in USDC.\n\nThe specific endpoint probed here returns an x402 challenge requesting up to 0.02 USDC (20,000 base units of USDC with 6 decimals) per call, consistent with the platform's advertised flat $0.02/request pricing. Payment is made via the `exact` scheme to a designated wallet address. The endpoint accepts HTTP POST requests and returns `application/json`. No API keys or rate limits are advertised; access is granted purely through on-chain payment.\n\nThe platform's documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all resolve but appear to require a wallet connection to render content, so detailed request/response schemas, parameter documentation, and example payloads are not available from the crawl. The endpoint's purpose — managing or retrieving Stripe subscription data — can be inferred from the URL path but is not explicitly documented in the crawled material. Without further documentation it is unclear what request body this POST endpoint expects or what the response payload looks like.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-subscriptions","pay-per-call","no-api-key","json-response"],"categories":["finance","infrastructure"],"synonyms":["stripe subscription API","x402 paid endpoint","USDC micropayment API","Base network API","pay-per-request API","lowpaymentfee","premium API access"],"warnings":["Documentation pages (/docs, /pricing, /api, /README) all require wallet connection and returned no useful content during crawl.","No request body schema or response schema is documented — unclear what POST body is expected.","The specific function of /api/v1/stripe/subscriptions/120 (create, read, update?) is not documented.","The broader platform lists many endpoints but none have detailed docs available without wallet auth."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/subscriptions/120","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/subscriptions/120","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and all documentation pages require wallet connection to render.
