Pay-per-call stock data for PANW via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for Palo Alto Networks (ticker: PANW) through an x402 payment-gated API. Each request costs $0.02 (20,000 base units of USDC on the Base network, where USDC has 6 decimals). The endpoint accepts POST requests and returns JSON. No API keys or accounts are required — callers authenticate and pay per-request using the x402 protocol with an X-PAYMENT header.
The provider, lowpaymentfee.com, hosts a broader suite of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced uniformly at $0.02 per request and settle on the Base L2 network in USDC. The site advertises no rate limits, no minimums, and instant access.
Documentation is extremely sparse. The /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the stock data response contains. The specific endpoint path suggests it returns data for the PANW ticker, but the exact response shape is unknown.
