Real-time stock price data for VRTX via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the current stock price for Vertex Pharmaceuticals (VRTX) through the lowpaymentfee.com platform. 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.
The 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`.
Documentation 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.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages beyond the landing page are empty. The listing is essentially a stub with only the x402 challenge and landing page to work from.
