Pay-per-call stock quote for RTX via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker RTX (Raytheon Technologies) through an x402 payment-gated API. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The endpoint accepts POST requests and returns JSON.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/stocks/RTX` falls under the finance category, though it is not explicitly listed on the landing page alongside the other finance endpoints (prices, rates, token quotes, gas estimates). This suggests the stocks path may be a dynamic route accepting arbitrary ticker symbols.
Payment is handled via the x402 protocol: callers send an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payee address on Base. The payment timeout is 300 seconds. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the docs pages are empty. The specific /stocks/RTX path is not listed on the provider's landing page, so its exact capabilities are inferred rather than documented.
