What it does

This endpoint provides historical stock price data for Boeing (ticker: BA) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI, and infrastructure services. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.

The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The x402 challenge was confirmed live, advertising a maxAmountRequired of 20,000 base units of USDC (0.02 USD given 6 decimals). The provider's landing page lists uniform $0.02 pricing across all endpoints.

Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact request body format and response structure for this stock history endpoint are unknown and must be discovered experimentally.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The request body format and response structure are entirely unknown, making this effectively a stub listing.

Warnings

  • —No OpenAPI or schema definition; request body format and response fields are unknown
  • —Only the BA (Boeing) ticker is confirmed at this path; availability of other tickers is unverified
  • —Provider site appears to be a generic multi-purpose API platform with uniform pricing; quality and depth of stock data is unverified
