What it does

This endpoint provides the EUR/CAD foreign exchange rate through a pay-per-call x402 protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of data, AI, finance, and utility APIs all priced at $0.02 per request, settled in USDC on the Base network. No API keys or rate limits are required — callers simply attach an x402 payment header to each POST request.

The specific endpoint at `/api/v1/forex/EURCAD/rate` returns the current EUR/CAD exchange rate in JSON format. The x402 challenge confirms the endpoint is live, accepting USDC (contract 0x8335…2913) on Base with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.

The broader lowpaymentfee.com platform also offers endpoints for analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), other finance data (price feeds, exchange rates, token quotes, gas estimates), and utility services (geocoding, validation, conversion, generation), all at the same $0.02 per-request price point. Documentation pages exist but appear to require wallet connection and contain minimal content beyond the landing page.

The x402 challenge is live and confirms pricing and payment details. However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the docs pages are effectively empty (wallet-gated). The endpoint's actual response structure must be inferred from the URL pattern alone.

Warnings

  • —No OpenAPI or schema documentation available for this endpoint
  • —Documentation pages (/docs, /api, /pricing, /README) appear to require wallet connection and contain no visible content
  • —Response format and fields are unknown — no example response is available
  • —The endpoint URL suggests a forex pair (EURCAD) but the platform's landing page lists it under generic 'Finance & Web3' without specific forex documentation
