What it does

This endpoint at lowpaymentfee.com returns the DYDX token wallet balance when called via HTTP POST with an x402 payment header. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.

The x402 challenge confirms the endpoint is live and accepts exact-scheme payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. The maxAmountRequired is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. No API keys or rate limits are advertised; access is gated solely by the x402 payment protocol. The response MIME type is application/json.

Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the balance response contains or what input parameters (if any) are expected in the POST body. The endpoint path suggests it returns a balance for the DYDX token, but the exact request format and response structure are unknown.
