What it does

This endpoint at lowpaymentfee.com provides stock data for the ticker EMR (Emerson Electric) through an x402 payment-gated API. Each request costs $0.02, paid in USDC on the Base network. The x402 challenge confirms the endpoint is live and accepts POST requests with an exact payment scheme. No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.

The provider (lowpaymentfee.com) hosts a broad catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. This specific endpoint sits in the finance category and returns JSON. However, no OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" stub. The exact fields returned for a stock query are unknown.

Because documentation is essentially absent beyond the landing page listing and the x402 challenge itself, consumers should expect to experiment with the POST body format. The endpoint is confirmed live (HTTP 402 challenge captured), the price is clear ($0.02 = 20,000 base units of USDC with 6 decimals), and settlement occurs on Base mainnet to address 0x1A2B…85F3.
