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.\n\nThe 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.\n\nThe 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.","tags":[],"capabilities":["forex-rate","eur-cad","x402-payment","usdc-base","pay-per-request","real-time-exchange-rate","no-api-key"],"categories":["finance","forex"],"synonyms":["EUR/CAD exchange rate","euro to canadian dollar","forex rate API","currency conversion","FX rate","foreign exchange rate","EURCAD"],"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"],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/EURCAD/rate","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/forex/EURCAD/rate","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The x402 challenge is live and confirms pricing and payment details.
