EUR/CAD forex rate via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides EUR/CAD foreign exchange rate data, accessible through the x402 payment protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com covering finance, analytics, AI/ML, crypto, and utility services. All endpoints on the platform share a uniform pricing model of $0.02 per request, settled in USDC on the Base network.
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 payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). No API keys or account registration are required — access is granted per-request upon valid payment. The platform advertises no rate limits.
Documentation beyond the landing page is sparse. The /docs, /pricing, /api, and /README pages all resolve to a minimal "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available from the crawled material. The exact fields returned (bid, ask, mid, timestamp, etc.) are not documented and must be inferred from the forex context.

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, no documented parameters, and no example payloads. All detail pages return only 'Connect wallet' with no usable documentation. The actual data returned must be entirely inferred from the endpoint path.
