The specific resource path (`/api/v1/stripe/subscriptions/87`) suggests a subscription-related API, though the exact functionality behind this particular endpoint is not documented in the crawled material. The provider's site advertises a broad suite of APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation).\n\nPayment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge specifies a maxAmountRequired of 20,000 base units, which at 6 decimals equals $0.02 per request — consistent with the site's advertised flat pricing of $0.02/request across all endpoints. The endpoint accepts POST requests and returns application/json. No API keys or rate limits are advertised; access is gated purely by the x402 payment protocol.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no detailed description of what this specific subscription endpoint returns. The endpoint is confirmed live (402 challenge captured successfully).","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","per-request-pricing","json-response","post-method","no-api-key","subscription-api"],"categories":["api-gateway","payments"],"synonyms":["x402 API","pay-per-request API","USDC API access","Base network API","lowpaymentfee","micropayment API","crypto-gated API"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'","No OpenAPI or schema describing request parameters or response format for this endpoint","The specific purpose of /api/v1/stripe/subscriptions/87 is unclear from available material","No request or response examples available anywhere in crawled content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/subscriptions/87","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/87","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).
