What it does

This endpoint provides NZD/CAD foreign exchange rate data, accessible through the x402 payment protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com covering finance, analytics, AI/ML, crypto, and utility services. Each request costs $0.02 (20,000 base units of USDC on the Base network, where USDC has 6 decimals). No API keys or accounts are required — callers pay per request using an x402-compatible wallet.

The endpoint accepts POST requests and returns JSON. The specific schema of the response (e.g., bid/ask, mid-rate, timestamp) is not documented in the crawled material, so the exact fields returned are unknown. The provider advertises no rate limits and instant access. Payment is settled on-chain via USDC on Base to the specified payTo address.

The site hosts many similar endpoints across categories (finance, AI, data, infrastructure), all at the same $0.02 price point. Documentation pages beyond the landing page returned only a "Connect wallet" prompt with no further technical detail, so the depth of documentation is very limited.

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation of request parameters, response schema, or example payloads. Doc pages returned only 'Connect wallet' with no technical content. The listing is essentially a stub with confirmed liveness.

  • —No OpenAPI spec or AI plugin manifest available
  • —Data freshness and source of forex rates are not disclosed
