Real-time stock price data for TJX via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns stock price data for TJX Companies (ticker: TJX) through the lowpaymentfee.com platform, an x402-enabled API marketplace. Payment is handled per-request via the x402 protocol on the Base network using USDC. Each call costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys, accounts, or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider hosts a broad catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. This specific endpoint is part of the finance category and serves stock price information. The response MIME type is application/json. The endpoint accepts POST requests and is marked as discoverable.
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. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the exact fields returned in a successful response are unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages are empty beyond a wallet-connect prompt. The listing is essentially a stub with only the x402 challenge and landing page to go on.
