Pay-per-call stock quote API for TSLA via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for TSLA (Tesla) behind an x402 paywall. It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, crypto, and utility services. The specific endpoint `/api/v1/stocks/TSLA` accepts POST requests and returns JSON.
Pricing is $0.02 per request, paid in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which has 6 decimals), equaling $0.02. No API keys are required; payment is handled inline via the X-PAYMENT header per the x402 protocol. The provider advertises no rate limits and instant access.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the stock data response contains. The endpoint is confirmed live (returns 402 with a valid x402 challenge), but the actual data quality and response format are unknown.

However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The actual data returned is completely undocumented, making this effectively a stub listing.
