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/176` is not explicitly listed among the site's documented API categories, so its exact functionality is unclear. The broader lowpaymentfee.com platform advertises a suite of pay-per-request APIs spanning Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure utilities (geocoding, validation, conversion, generation).
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum amount of 20,000 base units, which at 6 decimals equals $0.02 per request. This matches the site's advertised flat pricing of $0.02/request across all endpoints. The platform emphasizes no API keys, no rate limits, no minimums, and instant access — callers simply attach an x402 payment header to each request.
Because the `/api/v1/wire/176` path does not appear in the site's public API listing and the crawled documentation pages returned only "Connect wallet" with no further content, the exact input/output schema and purpose of this specific endpoint remain unknown. It may be a generic or internal route. Prospective callers should test with a single paid request to discover the response format.
