What it does

This endpoint returns the current GBP/AUD foreign exchange rate, accessible through the x402 payment protocol on the Base network. It is part of a broader suite of APIs offered by lowpaymentfee.com spanning finance, analytics, AI, and utility services, all priced at $0.02 per request paid in USDC.

The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment on Base (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. There are no API keys, no rate limits, and no signup required — access is granted per-request upon valid payment.

Documentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response, and no description of the response schema. The endpoint is confirmed live (returns 402 challenge), but the actual response format for the forex rate must be inferred.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages are empty beyond a wallet-connect prompt. The actual forex data quality and response format are unknown.

Warnings

  • No OpenAPI or schema documentation available — response format is unknown
  • All doc pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content
  • The specific /forex/GBPAUD/rate endpoint is not listed on the landing page; only /finance/rates is shown, so this may be an undocumented or auxiliary route
  • No information on data source, update frequency, or accuracy of the forex rate
