What it does

This endpoint provides GBP/CHF foreign exchange rate data, accessible via the x402 payment protocol on the Base network. It is part of a broader suite of APIs offered by lowpaymentfee.com covering 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 (contract 0x8335…2913). The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys, rate limits, or upfront commitments are needed — each call is independently paid.

Documentation on the site 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 request/response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request body format and response structure for the GBP/CHF forex data are unknown and must be discovered by the caller.
