AUD/NZD forex rate via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint provides AUD/NZD foreign exchange rate data, accessible via the x402 payment protocol on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, accounts, or rate limits — payment is handled per-call via an X-PAYMENT header settled in USDC on Base.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The forex endpoint specifically serves the AUD/NZD currency pair. The response MIME type is application/json, and the endpoint accepts POST requests.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation means the exact request body format and response structure are unknown.

Quality
