Payment is handled per-request using USDC on the Base network — no API keys, no subscriptions, no rate limits. Each call costs $0.02 (20,000 base units of USDC with 6 decimals).\n\nThe provider, lowpaymentfee.com, offers a broad catalog of pay-per-call endpoints spanning finance, AI/ML, data analytics, and utility services, all priced at $0.02 per request and settled on-chain via x402. This specific endpoint is a POST request that returns JSON. The x402 challenge is live and well-formed, advertising x402 version 1 with a 300-second payment timeout.\n\nDocumentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is confirmed live (402 challenge captured), but the actual data source and response format are unknown.","tags":[],"capabilities":["stock-price","real-time-market-data","x402-payment","usdc-base","per-request-billing","no-api-key","json-response"],"categories":["finance","market-data"],"synonyms":["REGN stock price","Regeneron stock quote","stock price API","equity price lookup","real-time stock data","x402 stock API","micropayment stock price"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc/pricing/README pages return only a 'Connect wallet' prompt with no technical content","Data source for stock prices is undisclosed; accuracy and freshness cannot be verified","No example request or response payloads are provided by the provider"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/REGN/price","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/stocks/REGN/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages render only a wallet-connect prompt.
