What it does

This endpoint provides historical stock price data for Danaher Corporation (ticker: DHR) through the lowpaymentfee.com platform. It is part of a broader suite of finance, analytics, AI, and utility APIs offered by the same provider, all accessible via the x402 payment protocol on the Base network.

The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) using the x402 "exact" scheme. The maximum amount required per request is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised — access is gated purely by the per-call micropayment.

Documentation is extremely sparse. The provider's landing page lists available endpoints and pricing, but the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact fields returned in the historical stock data response (e.g., OHLCV candles, date ranges, granularity) are unknown and must be discovered by making a paid request.

Quality

0.35/ 1.00

The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page, and no example payloads. The actual data format and query parameters are entirely unknown.

Warnings

  • —No documentation available — /docs, /pricing, and /README pages all show only 'Connect wallet' with no content.
  • —No OpenAPI or request/response schema provided; the structure of both input and output is unknown.
  • —Stock data source and freshness are unverified; no information on data provider, update frequency, or date range coverage.
  • —The endpoint path is ticker-specific (/stocks/DHR/history); it is unclear whether other tickers are supported or how to discover them.
