What it does

This endpoint provides GBP/NZD foreign exchange rate data accessible through the x402 payment protocol. It is hosted at lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning finance, AI, data analytics, and utility services. Each call costs $0.02 (20,000 base units of USDC on the Base network, where USDC uses 6 decimals). No API keys or accounts are required — payment is handled inline via the x402 X-PAYMENT header.

The endpoint accepts POST requests and returns JSON. Based on the URL path (`/api/v1/forex/GBPNZD`), it serves the British Pound to New Zealand Dollar exchange rate. The broader lowpaymentfee.com platform lists additional forex, crypto, AI, and utility endpoints all at the same $0.02 price point. The site advertises no rate limits and instant access.

Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data format and fields returned are unknown and must be inferred from the endpoint path alone.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation, no example requests or responses, and no description of the response schema. The listing is essentially a stub with only the payment challenge and homepage listing to go on.

Warnings

  • No documentation available — /docs, /pricing, /api, and /README pages all return only a wallet-connect prompt with no content.
  • No OpenAPI or schema definition found; response format is entirely unknown.
  • No example request or response payloads available; actual data fields must be discovered empirically.
  • The specific /forex/GBPNZD endpoint is not listed on the homepage (only /finance/rates and /finance/prices are shown), so its existence and behavior are inferred from the URL and 402 challenge alone.
