Pay-per-call earnings data for ADP stock via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides earnings data for ADP (Automatic Data Processing) via a simple POST request, gated by the x402 payment protocol. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The payment is settled on-chain to a specified wallet address using the "exact" scheme.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning finance, analytics, AI/ML, crypto, and utility categories, all priced at $0.02 per request. The specific `/api/v1/finance/ADP/earnings` path targets earnings report data for the ADP ticker symbol, though the exact response schema is not documented in the available materials.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI spec, no example request/response payloads, and no description of what fields the earnings data includes. The x402 challenge is live and well-formed, confirming the endpoint is operational, but consumers should expect to experiment to discover the response format.

Quality
The x402 challenge is live and well-formed, confirming the endpoint works 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 listing is effectively a stub with only the payment challenge and homepage to go on.
Warnings
- —No OpenAPI spec or response schema available — response format is unknown
- —Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no content
- —No example request or response payloads documented anywhere
- —Exact data source for ADP earnings is unspecified — unclear if data is real-time, historical, or how fresh it is
