Pay-per-call stock data for ticker ADI 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 ADI (Analog Devices, Inc.) through an x402 payment-gated API. Each request costs $0.02, paid in USDC on the Base network. 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, infrastructure utilities, and stock data. All endpoints share the same $0.02/request pricing model with no API keys, no rate limits, and no minimum commitments — payment is handled entirely via the x402 protocol's X-PAYMENT header using USDC on Base.
The specific endpoint `/api/v1/stocks/ADI` is not explicitly listed on the provider's landing page among the showcased APIs, but the x402 challenge confirms it is live and accepting payments. Documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the exact request body schema and response fields for stock data are unknown. Callers should expect a JSON response with stock-related information for ADI, but the precise structure must be discovered experimentally.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no documentation, no request/response schema, and the /stocks/ADI endpoint is not even listed on the provider's own landing page. All doc pages return only 'Connect wallet' with no useful content.
