Pay-per-call premium API access on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/wire/102` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities. All endpoints are gated via the x402 protocol, settling payments in USDC on the Base network. The listed price is $0.02 per request (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC, which equals $0.02 given USDC's 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The specific `/api/v1/wire/102` route is labeled "Premium API Access" in the x402 challenge, but the site does not provide detailed documentation for this particular path. The landing page lists 16 other endpoints across four categories (analytics/metrics, AI inference, finance/crypto data, and utility services), all priced identically at $0.02. The `/wire/102` route does not appear in the public catalog, so its exact functionality is unclear — it may be an unlisted or internal endpoint. The endpoint accepts POST requests and returns `application/json`.
Documentation is extremely sparse: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawl.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and the specific /wire/102 route is not listed in the public catalog. Effectively a stub listing.
