Stock market quote for TJX via x402 micropayment on Base, $0.02 per request in USDC.
What it does
This endpoint provides a stock market quote for the ticker symbol TJX (TJX Companies, Inc.) 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 costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.
The endpoint accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach 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 payTo address on Base. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for the TJX quote endpoint. The exact fields returned (e.g., price, volume, timestamp) are unknown and must be discovered by making a paid call.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation of request parameters or response schema, and no example payloads. The docs pages are empty beyond a wallet-connect prompt, making this effectively a stub listing.
