Real-time stock price data for NKE (Nike) via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the current stock price for Nike (ticker: NKE) 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 endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. The stock price endpoint specifically lives under the finance category and is accessed via HTTP POST. The response MIME type is application/json.
Documentation on the site is minimal — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema beyond the MIME type. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the exact shape of the returned stock price data is unknown.

Quality
The endpoint is confirmed live via a valid 402 x402 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 the docs pages are empty stubs. The listing is essentially a stub with only the challenge metadata to go on.
