Pay-per-call premium API access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" via the x402 payment protocol. The specific endpoint `/api/v1/wire/87` is one of many API routes offered by the platform, which spans categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities. All endpoints are priced at $0.02 per request, payable in USDC on the Base network with no API keys, no rate limits, and no commitments required.
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is settled on-chain to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maximum amount required is 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The response MIME type is `application/json`.
However, the specific functionality behind `/api/v1/wire/87` is not documented — the endpoint name "Premium API Access" is generic and does not clarify what data or service it returns. The platform's docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional documentation. Without an OpenAPI schema, request/response examples, or detailed docs, the actual behavior of this particular endpoint remains unclear.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but the specific endpoint's functionality is entirely undocumented. No OpenAPI schema, no request/response examples, and all doc pages render only a wallet-connect prompt. The listing is effectively a stub.
