Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, rate limits, or upfront commitments — you pay per call using an on-chain USDC micropayment.\n\nThe endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. The forex rate endpoint specifically serves the GBP/NZD currency pair. The endpoint accepts POST requests and returns JSON.\n\nDocumentation beyond the landing page is sparse — the /docs, /api, /pricing, and /README pages all resolve to a minimal \"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 via a valid 402 challenge, but the actual data source and response format are unknown.","tags":[],"capabilities":["forex-rate","gbp-nzd","x402-payment","usdc-base","per-request-pricing","no-api-key","micropayment"],"categories":["finance","forex"],"synonyms":["GBP NZD exchange rate","British pound New Zealand dollar rate","forex rate API","currency conversion","FX rate","foreign exchange rate","GBPNZD"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' stub with no content","Data source for forex rates is undisclosed; accuracy and freshness are unverifiable","No SLA, uptime, or latency guarantees documented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/GBPNZD/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/GBPNZD/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 x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
