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/116` is one of many endpoints offered by the platform, which spans categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities. All endpoints on the platform are priced at $0.02 per request, paid 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, accepting POST requests and settling payments in USDC (contract `0x8335...2913` on Base). The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per call. Payment is made via the `exact` scheme with a 300-second timeout. The output is `application/json`.
The specific functionality behind `/api/v1/wire/116` is not documented — the platform's landing page lists various named endpoints (metrics, reports, sentiment analysis, summarization, etc.) but does not reference this particular wire path. It may be a generic or internal routing endpoint. Without further documentation or example responses, the exact data returned by this endpoint remains unclear.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but the specific functionality of /api/v1/wire/116 is undocumented. No OpenAPI schema, no example requests/responses, and the crawled docs/pricing/README pages all returned only 'Connect wallet' with no useful content. The endpoint's purpose must be guessed.
