Pay-per-call stock quote for JPM via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for JPM (JPMorgan Chase) via a simple POST request, paid per call using the x402 protocol. Payment is settled on the Base network in USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or accounts are required — callers attach an X-PAYMENT header with a valid x402 payment proof and receive a JSON response.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/stocks/JPM` falls under the finance category and presumably returns stock price or quote data for JPMorgan Chase, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live, accepts POST requests, and is discoverable.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response, and no description of the response payload beyond the generic "Premium API Access" label. Callers should expect a JSON response but will need to experiment to determine the exact fields returned.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing and network details. However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty stubs. The listing is essentially a stub with only the x402 challenge and homepage catalog to work from.
Warnings
