Pay-per-call premium API access on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" via the x402 payment protocol. The specific resource path `/api/v1/wire/183` is not explicitly listed on the provider's landing page among their documented API categories, so its exact functionality is unclear. The provider's site advertises a broad suite of pay-per-call APIs spanning Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request.
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The endpoint requires no API keys, advertises no rate limits, and provides instant access — the only gate is the x402 micropayment. The response MIME type is application/json.
Because the `/api/v1/wire/183` path does not appear in the provider's public API listing and no OpenAPI schema, documentation, or example responses are available for this specific route, the actual data or service it returns is unknown. The docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. Prospective callers should be aware that this is an opaque endpoint with no documented input/output schema beyond the x402 challenge metadata.

No OpenAPI schema, no input/output examples, and all documentation pages render only a wallet-connect prompt. The actual service behind this endpoint is unknown.
