Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, accounts, or rate limits — payment is handled per-call via an X-PAYMENT header settled in USDC on Base.\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 priced uniformly at $0.02 per request. The forex endpoint specifically serves the AUD/NZD currency pair. The response MIME type is application/json, and the endpoint accepts POST requests.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation means the exact request body format and response structure are unknown.","tags":[],"capabilities":["forex-rate","aud-nzd","x402-payment","usdc-base","per-request-micropayment","json-response"],"categories":["finance","forex"],"synonyms":["AUD NZD exchange rate","Australian dollar New Zealand dollar","forex pair","currency rate","FX rate","AUDNZD spot price"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages are all empty (only show 'Connect wallet')","No OpenAPI or schema definition found; request body format and response structure are unknown","The endpoint description is generic ('Premium API Access') and does not describe the forex data returned","Cannot verify what data fields (bid, ask, mid, timestamp, etc.) are included in the response"],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/AUDNZD","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/AUDNZD","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 with a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base).
