It is part of a broader suite of APIs offered by lowpaymentfee.com spanning finance, analytics, AI/ML, crypto, and utility services — all priced at $0.02 per request paid in USDC (Base).\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment of up to 0.02 USDC (maxAmountRequired=20000 base units, 6 decimals) to the payTo address on Base. No API keys, accounts, or rate limits are advertised — access is purely pay-per-call.\n\nDocumentation beyond the landing page is extremely thin. The /docs, /pricing, /api, and /README pages all resolve to a near-empty \"Connect wallet\" stub, so there is no published request/response schema, no example payloads, and no detailed description of what fields the forex endpoint returns. The endpoint is confirmed live (402 challenge captured), but the actual data source, update frequency, and response format are unknown.","tags":[],"capabilities":["forex-rate","eur-nzd","x402-payment","usdc-base","pay-per-request","json-response"],"categories":["finance","forex"],"synonyms":["EUR/NZD exchange rate","euro to new zealand dollar","forex API","currency conversion","FX rate","foreign exchange rate","EURNZD"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README all return only a 'Connect wallet' stub.","No request or response schema published; actual forex data fields are unknown.","Data source, update frequency, and accuracy of the EUR/NZD rate are undocumented.","The provider hosts dozens of heterogeneous endpoints (AI, analytics, crypto, utils) all at $0.02 — quality and depth of each is unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/EURNZD","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/EURNZD","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
