What it does

This endpoint at lowpaymentfee.com provides EUR/JPY foreign exchange rate data via a simple POST request. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning finance, analytics, AI/ML, crypto, and utility categories. Payment is handled through the x402 protocol: each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.

The x402 challenge confirms the endpoint is live and accepts payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The response MIME type is application/json. No detailed documentation, request/response schemas, or example payloads were found in the crawled material — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.

Because there is no published schema describing the response format (e.g., bid/ask, mid-rate, timestamp, source), consumers should expect a JSON object with forex pricing fields but will need to discover the exact structure empirically. The provider's landing page lists a uniform $0.02/request price across all endpoints and advertises no rate limits and instant access.
