What it does

This endpoint provides historical stock price data for Intel Corporation (INTC) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI/ML, and infrastructure services. Payment is handled via the x402 protocol on the Base network using USDC, with each request costing $0.02 (20,000 base units of USDC with 6 decimals).

The endpoint accepts POST requests and returns JSON. No API keys or account registration are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access. The x402 challenge was successfully captured, confirming the endpoint is live.

Documentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all returned 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 historical stock data response contains or what query parameters (date range, interval, etc.) are supported. The endpoint path suggests it returns historical price data for the INTC ticker, but the exact shape of the request body and response payload must be discovered by calling the endpoint.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The actual data format and supported parameters are unknown.

Warnings

  • —No documentation available — /docs, /pricing, /api, and /README pages all return only a wallet-connect prompt with no content
  • —No OpenAPI or schema describing request parameters (e.g., date range, interval) or response fields
  • —Request body format and response structure must be discovered empirically
  • —The provider hosts many diverse API categories (AI, finance, infrastructure) at uniform $0.02 pricing, which may indicate a thin wrapper or placeholder service
