It is part of the lowpaymentfee.com platform, which offers a broad suite of pay-per-request APIs spanning finance, analytics, AI/ML, and utilities. The endpoint is accessed via HTTP POST and is gated by the x402 payment protocol, settling in USDC on the Base network.\n\nPricing is $0.02 per request (20,000 base units of USDC with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is paid individually via the X-PAYMENT header. The x402 challenge was confirmed live, returning a standard 402 response with payment parameters.\n\nThe specific response schema for the EUR/JPY history endpoint is not documented in the crawled material. The site's docs, pricing, and API pages all rendered only a wallet-connect prompt with no additional technical documentation. As a result, the exact request body format (e.g., date ranges, granularity options) and response structure (OHLCV candles, close prices, etc.) must be discovered by calling the endpoint. The endpoint is listed under the \"Finance & Web3\" category on the provider's homepage alongside price feeds, exchange rates, token quotes, and gas estimates.","tags":[],"capabilities":["forex-history","eurjpy","x402-payment","usdc-base","pay-per-request","historical-data","finance-api"],"categories":["finance","forex"],"synonyms":["EUR/JPY historical data","forex history API","euro yen exchange rate","currency pair history","FX rate history","EURJPY candles","forex market data"],"warnings":["No API documentation available — docs, pricing, and API pages only show a wallet-connect prompt with no technical content.","Request body schema and response format are unknown; the example_request_json is speculative.","The endpoint is part of a platform with many generic-looking APIs; actual data quality and sources are unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/forex/EURJPY/history","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/EURJPY/history","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base).
