Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, accounts, or rate limits — just an x402-compatible payment header.\n\nThe endpoint is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/crypto market data, and utility services. All endpoints on the platform share the same $0.02-per-request pricing model and settle payments in USDC on Base. The forex rate endpoint specifically serves the NZD/CAD currency pair and responds with JSON.\n\nDocumentation on the site is extremely sparse — 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 example request/response payloads, and no description of the response schema. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual response format must be inferred from the endpoint path and general conventions.","tags":[],"capabilities":["forex-rate","nzd-cad","x402-payment","usdc-settlement","base-network","per-request-pricing","no-api-key"],"categories":["finance","forex"],"synonyms":["NZD CAD exchange rate","New Zealand dollar Canadian dollar","forex rate API","currency conversion","FX rate","NZD/CAD spot rate","currency pair rate"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc/pricing/API/README pages render only 'Connect wallet' with no content","No example request or response payloads could be found","The specific forex data source and update frequency are undisclosed"],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/NZDCAD/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/NZDCAD/rate","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 x402 challenge, and pricing is clear ($0.02 USDC on Base).
