It uses the x402 payment protocol, settling in USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. This specific endpoint is part of the finance category and follows a RESTful pattern: POST to `/api/v1/stocks/{ticker}/price`. The response MIME type is `application/json`.\n\nDocumentation beyond the landing page is sparse — the /docs, /pricing, /api, 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 (returns a proper 402 challenge), but the exact shape of the successful response is unknown.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-settlement","base-network","per-request-micropayment","no-api-key","real-time-data"],"categories":["finance","data"],"synonyms":["stock price API","VRTX stock price","equity price lookup","Vertex Pharmaceuticals price","stock market data","micropayment stock API","pay-per-call stock data"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc/pricing/README pages return only a 'Connect wallet' prompt with no content","No example responses available; the exact fields returned on successful payment are unverified","This endpoint appears to serve financial market data, which may be subject to data licensing and redistribution restrictions"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/VRTX/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/VRTX/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
