Historical AUD/USD forex data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides historical forex data for the AUD/USD currency pair. It is part of the lowpaymentfee.com platform, which offers a range of pay-per-request APIs spanning data analytics, AI/ML, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network at $0.02 per request with no API keys, rate limits, or subscriptions required.
The specific endpoint at `/api/v1/forex/AUDUSD/history` accepts POST requests and returns JSON. The x402 challenge confirms it is live, advertising a maxAmountRequired of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 `exact` scheme to the provider's wallet address.
Documentation on the platform is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the history endpoint accepts or returns. The endpoint name and platform category (Finance & Web3) suggest it returns historical price or OHLC data for AUD/USD, but the exact request parameters and response format are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and network. However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The exact request parameters and response shape are completely unknown, making this effectively a stub listing.
