Historical stock price data for GOOGL via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides historical stock price data for Google (GOOGL) through the lowpaymentfee.com platform. It uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request. No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the data.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per call. The specific endpoint at `/api/v1/stocks/GOOGL/history` accepts POST requests and returns JSON. However, the crawled documentation pages (docs, pricing, API reference) were essentially empty beyond a "Connect wallet" prompt, so details about request parameters, response schema, and the exact historical data fields returned are not documented in the available material.
The x402 challenge was successfully captured, confirming the endpoint is live. The payment is settled via USDC (contract 0x8335…2913) on Base with a max amount of 20,000 base units, which equals $0.02 given USDC's 6 decimals. The timeout is 300 seconds. While the endpoint is functional, the lack of request/response schema documentation limits confidence in integration without trial-and-error.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no documented request schema, no response schema, no examples, and the docs/pricing/API pages are all blank beyond a wallet-connect prompt. The actual data returned is entirely unknown.
Warnings

- —No response schema or example response documented
- —Docs, pricing, and API reference pages are effectively empty (only show 'Connect wallet')
- —Stock ticker is hardcoded in the URL path; unclear if other tickers are supported at similar paths
- —Cannot verify data source or freshness of historical stock data
