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 resource path `/api/v1/wire/146` is not individually described in the provider's documentation, but it belongs to a broader platform that offers a suite of pay-per-request APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities. All endpoints on the platform are priced at $0.02 per request, payable in USDC on the Base network with no API keys, rate limits, or commitments required.
The x402 challenge confirms the endpoint is live, accepting POST requests and settling payments in USDC (contract 0x8335…2913 on Base) to address 0x1A2B…85F3. The maxAmountRequired of 20,000 base units (USDC has 6 decimals) translates to $0.02 per call, consistent with the site's advertised pricing. The response MIME type is application/json.
However, the specific functionality behind `/api/v1/wire/146` is unclear. It does not appear in the provider's listed API catalog, and no documentation, input schema, or example responses are available for this particular route. The crawled docs, pricing, API, and README pages all rendered only a "Connect wallet" prompt with no additional content. Without knowing what this endpoint actually returns, consumers should treat this as an opaque premium endpoint until more documentation surfaces.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but the specific functionality of /api/v1/wire/146 is undocumented. No input schema, output schema, or example responses are available. The crawled documentation pages were effectively empty. This is essentially a stub listing.
