What it does

This endpoint provides NZD/CHF (New Zealand Dollar to Swiss Franc) foreign exchange rate data, accessible through the x402 payment protocol on the Base network. Each request costs $0.02, paid in USDC (USD Coin) with no API keys, rate limits, or subscriptions required.

The endpoint is part of a broader suite of APIs offered at lowpaymentfee.com spanning finance, analytics, AI/ML, crypto, and utility categories — all priced at $0.02 per call. The forex endpoint specifically serves the NZD/CHF currency pair and returns JSON. Payment is handled inline via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment on Base, and the server fulfills the request upon verification.

No OpenAPI schema or detailed documentation was found beyond the landing page. The endpoint is confirmed live (returns a proper 402 challenge). The exact response format is undocumented, so callers should expect a standard JSON object containing exchange rate information, but the precise fields are unknown.

Quality

0.40/ 1.00

The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 in USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and the docs/pricing/README pages all returned only a 'Connect wallet' stub with no useful content. The response structure must be guessed.

Warnings

  • —No OpenAPI or response schema available — response format is unknown
  • —Documentation pages (/docs, /pricing, /README) contain no useful content
  • —Exact data source, update frequency, and accuracy of forex rates are undocumented
  • —This is a single currency pair endpoint; no information on whether it returns live, delayed, or indicative rates
