Pay-per-call stock quote API for HON (Honeywell) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker HON (Honeywell International) through an x402-gated API. Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required — callers simply attach an x402 payment header to a POST request and receive a JSON response.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced at $0.02 per request. The specific /api/v1/stocks/HON route appears to serve stock-level data for Honeywell, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live, accepts USDC (contract 0x8335…2913) on Base, and requires a maximum payment of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the data fields returned. Callers should expect a JSON response but will need to experiment to discover the exact schema.
