Get the current stock price for MO (Altria Group) via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current stock price for the ticker MO (Altria Group) through a simple HTTP POST call, paid per request using the x402 protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com covering data analytics, AI/ML inference, finance, crypto, and utility services — all sharing the same pay-per-use model.
The endpoint accepts x402 payments on the Base network using USDC (contract 0x8335…2913). Each request costs a maximum of $0.02 (20,000 base units at 6 decimals). There are no API keys, no rate limits, and no subscriptions — you simply attach an X-PAYMENT header with a valid x402 payment proof and receive a JSON response. The payment timeout is 300 seconds.
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 schema, no example request/response, and no description of the response payload structure. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data source for stock prices and the response format are unknown.
