Pay-per-call audit log access on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 34) via the x402 payment protocol. It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform share a uniform $0.02-per-request pricing model, paid in USDC on the Base network with no API keys, rate limits, or commitments required.
The specific endpoint `/api/v1/audit/logs/34` is labeled "Premium API Access" and accepts POST requests. Payment is handled via the x402 protocol: callers receive a 402 challenge containing payment parameters (asset, amount, payTo address), construct a signed USDC payment, and include it in the X-PAYMENT header on retry. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. The response MIME type is application/json.
Documentation on the site is extremely thin — 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 documentation, and no example payloads available. The exact structure of the audit log data returned is unknown. The endpoint is confirmed live (402 challenge captured successfully).

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no example payloads. The purpose of 'audit logs' is not explained. This is effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and README pages all render only 'Connect wallet'
- —No OpenAPI or JSON schema for request or response bodies
- —The exact data returned by /api/v1/audit/logs/34 is unknown
- —The endpoint path references a specific log ID (34); it is unclear if other IDs are supported or what the resource represents
