x402-gated premium API access on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" behind an x402 paywall on the Base network. The specific resource `/api/v1/trades/184` appears to be part of a broader platform offering data & analytics, AI/ML inference, finance/Web3 data, and infrastructure utility endpoints — all priced at $0.02 per request paid in USDC (USD Coin) on Base.
The x402 challenge confirms the endpoint is live, accepting POST requests and settling payments via the "exact" scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys or rate limits are advertised; access is granted per-request upon payment. The response MIME type is `application/json`.
However, the specific functionality of `/api/v1/trades/184` is unclear. The path suggests a trades-related resource (possibly returning data for a specific trade with ID 184), but no documentation, request schema, or response schema is available for this particular endpoint. The site's docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. The platform advertises many endpoint categories but provides no detailed documentation for any of them.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, and no explanation of what /api/v1/trades/184 actually returns. The site's doc pages are empty beyond a wallet connect prompt. This is effectively a stub listing.
Warnings
- —No documentation available for this specific endpoint — the /docs, /pricing, /api, and /README pages all render only a 'Connect wallet' prompt with no content.
- —The purpose of /api/v1/trades/184 is unclear; the path suggests trade data but no schema or description exists.
- —No request body schema or response schema is provided, making integration risky without trial calls.
- —The endpoint path includes a hardcoded ID (184), suggesting it may be a single-resource lookup rather than a general-purpose trades API.
