NZD/USD forex rate via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint provides NZD/USD foreign exchange rate data, accessible through 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, and utility services, all priced at $0.02 per request. The forex endpoint specifically serves the NZD/USD currency pair and returns JSON. The x402 challenge confirms the endpoint is live, using the "exact" payment scheme with a 300-second timeout.
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 request/response schema documentation, and no example payloads available. The input schema indicates it accepts HTTP POST requests. Without documented request body parameters or response format, consumers will need to experiment or inspect responses to understand the data structure returned.

Quality
The endpoint is confirmed live via 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 examples, and all documentation pages render only a wallet-connect prompt. The listing is effectively a stub with confirmed liveness.
