What it does

This endpoint returns the current GBP/CAD foreign exchange rate, accessible via 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/ML, crypto, 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. No API keys, accounts, or rate limits are advertised — access is purely pay-per-call.

Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the forex rate response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format must be inferred.

Quality

0.35/ 1.00

The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and all documentation pages are empty beyond a wallet-connect prompt. The listing is essentially a stub with verified liveness.

Warnings

  • No API documentation available — /docs, /pricing, and /README pages are empty
  • No request or response schema provided; actual output format is unknown
  • The provider hosts many generic-sounding endpoints (analytics, AI, crypto, utils) all at the same price, which may indicate placeholder or thin services
