CRM earnings data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint provides finance/CRM earnings data accessible through the x402 payment protocol on the Base network. It is part of a broader suite of APIs offered by lowpaymentfee.com covering data analytics, AI/ML inference, finance/Web3, and infrastructure utilities.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC (USD Coin) on Base at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — access is granted immediately upon valid x402 payment. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 and the USDC contract used is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all show only a "Connect wallet" prompt with no further content. The specific request schema and response format for the CRM/earnings endpoint are not documented anywhere in the available material, so the exact fields accepted and returned remain unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear, but there is zero documentation on request/response schemas, no OpenAPI spec, and all doc pages render only a wallet-connect prompt. The actual data returned is entirely unknown.

- —All documentation pages (docs, API, pricing, README) show only 'Connect wallet' with no content
