Historical stock price data for PANW via x402 micropayment on Base, $0.02/request.
What it does
This endpoint provides historical stock price data for Palo Alto Networks (PANW) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, AI/ML, data analytics, and infrastructure utilities. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint accepts POST requests and returns JSON. The specific URL path includes the ticker symbol PANW, suggesting the platform likely offers similar `/stocks/{ticker}/history` routes for other symbols, though only this endpoint was probed. The provider's landing page lists many other endpoints across finance, crypto, AI, and utility categories, all at the same $0.02 price point.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation means callers will need to experiment to discover the expected request body format and response structure.

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