Historical EUR/NZD forex data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint provides historical foreign exchange data for the EUR/NZD currency pair. It is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning finance, analytics, AI, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled via the X-PAYMENT header using the x402 exact scheme — no API keys, accounts, or rate limits are required. The max amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using the USDC contract on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no description of request parameters (e.g., date range, granularity), and no example responses. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data format and available query parameters must be discovered by making a paid request.

Quality
