What it does

This endpoint at lowpaymentfee.com provides stock data for the ticker BA (Boeing) via a simple POST request, paid per call using the x402 protocol. The price is $0.02 per request, settled in USDC on the Base network. No API keys or accounts are required — callers attach an x402 payment header and receive a JSON response.

The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all at the same $0.02/request price point. The specific endpoint `/api/v1/stocks/BA` is not listed on the site's landing page catalog (which focuses on analytics, AI, finance, and utility categories), so it may be an unlisted or legacy route. The x402 challenge confirms it is live and accepting payments.

Pricing: The x402 challenge specifies a maxAmountRequired of 20000 base units of USDC (token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, 6 decimals), which equals $0.02 per request. Payment timeout is 300 seconds. No rate limits or minimums are advertised.

Quality

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no documentation for the /stocks/BA route specifically, no request/response schema, no example payloads, and the endpoint is not listed in the site's own catalog.

  • Documentation pages (/docs, /pricing, /README) returned no meaningful content beyond 'Connect wallet'.
  • No information on data source, update frequency, or accuracy of stock quotes.
