Historical stock data for ABBV via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides historical stock price data for AbbVie Inc. (ticker: ABBV) through the x402 payment protocol. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services. Each request is settled on the Base network using USDC, with no API keys, rate limits, or subscriptions required.
The endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a maximum cost of $0.02 per call (20,000 base units of USDC with 6 decimals = $0.02). Payment is made via the x402 "exact" scheme to a specified wallet address on Base. The response MIME type is application/json.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact request body format and the structure of the historical stock data response are unknown and must be discovered experimentally.
