Each request costs $0.02 (20,000 base units of USDC on the Base network, where USDC uses 6 decimals). No API keys or accounts are required — callers simply attach an x402 payment header to a POST request and receive the rate data as JSON.\n\nThe endpoint is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/crypto, and utility services, all priced at $0.02 per call. The forex endpoint specifically targets the USD to Mexican Peso pair. Payment is settled on-chain via USDC (contract 0x8335…2913) on the Base L2 network, with a 300-second payment timeout window.\n\nDocumentation beyond the landing page is sparse — the /docs, /pricing, and /api pages all render only a \"Connect wallet\" prompt with no additional 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 challenge), but the exact shape of the returned forex data must be inferred.","tags":[],"capabilities":["forex-rate","usd-mxn","x402-payment","usdc-base","micropayment","real-time-exchange-rate","no-api-key"],"categories":["finance","forex"],"synonyms":["USD MXN exchange rate","dollar peso rate","forex API","currency conversion","FX rate","Mexican peso rate","USDMXN"],"warnings":["No OpenAPI or JSON schema available for request or response payloads","Documentation pages (/docs, /pricing, /api) contain no usable content beyond 'Connect wallet'","Response format for the forex rate is unknown — no examples found in crawl material","The broader lowpaymentfee.com platform lists many endpoints but provides no detailed docs for any of them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/USDMXN/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/USDMXN/rate","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base).
