Pay-per-call audit logs endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at `/api/v1/audit/logs/6` is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol on the Base network, accepting USDC (USD Coin) with no API keys, no rate limits, and no subscriptions required.
The specific endpoint probed (`/api/v1/audit/logs/6`) is described as "Premium API Access" and costs $0.02 per request (20,000 base units of USDC with 6 decimals). It accepts POST requests and returns `application/json`. Payment is made via the x402 exact scheme to the payTo address on Base, with a max timeout of 300 seconds. The broader platform advertises a uniform $0.02/request pricing across all its endpoints.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual functionality behind "audit/logs/6" is unclear beyond the generic "Premium API Access" label. The platform appears to be a demonstration or early-stage x402 API marketplace.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing, but there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The actual functionality of 'audit/logs/6' is undefined beyond a generic label. This is effectively a stub listing.
