Pay-per-call stock data for ADP via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for ADP (Automatic Data Processing) through an x402-protocol pay-per-call API. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment to the payTo address, and the server returns the data in JSON.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of endpoints across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all at the same $0.02/request price point. The specific /api/v1/stocks/ADP route is a POST endpoint that presumably returns stock-related information for the ADP ticker, though the exact response schema is not documented.
Note that 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 response schema, and no example payloads available. The endpoint is confirmed live (returns a valid 402 challenge), but the actual data content and response format must be discovered empirically.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty stubs. The actual data returned is unknown, making this effectively a stub listing.
