What it does

This endpoint provides the GBP/CHF (British Pound to Swiss Franc) 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.

The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) using the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD — consistent with the provider's advertised flat pricing of $0.02 per request across all endpoints. No API keys are needed; access is granted per-request via the X-PAYMENT header. The provider advertises no rate limits and instant access.

Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available from the crawl. The exact structure of the response (e.g., whether it includes bid/ask, timestamp, or just a mid-rate) is unknown and must be inferred from the endpoint path and category description.

Quality

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, and all documentation pages return only a wallet-connect prompt. The exact response format is unknown, making this effectively a stub listing.

Warnings

  • —No documentation available — /docs, /pricing, /api, and /README all render only 'Connect wallet' with no technical content.
  • —No OpenAPI or schema definition found; request body and response structure are entirely unknown.
  • —The specific /forex/GBPCHF/rate path is not listed on the provider's landing page, though similar finance endpoints are. This endpoint may be undocumented or dynamically routed.
  • —Response format (fields, structure) is inferred and unverified.
