What it does

This endpoint provides historical stock price data for Amazon (AMZN) through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning data analytics, AI/ML, finance, crypto, and utility services. All endpoints on the platform use the same pricing model: $0.02 per request, settled in USDC on the Base network with no API keys, rate limits, or commitments required.

The specific endpoint at `/api/v1/stocks/AMZN/history` accepts POST requests and returns JSON. The x402 challenge confirms it is live, requesting a maximum of 20,000 base units of USDC (0.02 USD) per call, paid to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. The platform appears to host a broader set of stock endpoints (the `/stocks/` path pattern), though only the AMZN history endpoint was probed.

Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical data includes (e.g., OHLCV, date ranges, granularity). Prospective users should expect to experiment with the endpoint to discover its input parameters and output format.

Quality

0.35/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and documentation pages are empty beyond a wallet connect prompt. The actual data format, supported parameters, and coverage are entirely unknown.

Warnings

  • —No OpenAPI or input/output schema provided; request parameters and response format are unknown
  • —No examples of actual response data; unclear what historical fields (OHLCV, date range, granularity) are returned
  • —Only the AMZN ticker was probed; availability of other tickers is unconfirmed
