Pay-per-call audit log endpoint 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 entry 71) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.
The specific resource `/api/v1/audit/logs/71` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an `X-PAYMENT` header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02) to the provider's wallet on Base. There are no API keys, no rate limits, and no subscription commitments — each call is independently paid.
The platform's landing page lists additional endpoint categories (metrics, reports, sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, validation, and more), all following the same $0.02/request x402 payment model. Documentation pages beyond the landing page were largely empty at crawl time, so detailed request/response schemas for this specific audit-log endpoint are not available.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs. The specific purpose of 'audit/logs/71' is not explained beyond the generic 'Premium API Access' label, making this effectively a stub listing.
Warnings
- —No OpenAPI or detailed schema available for this endpoint
- —Documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no actual content
- —The specific data returned by /api/v1/audit/logs/71 is undocumented — 'Premium API Access' is a generic label
- —The endpoint path references a specific log ID (71); it is unclear whether other IDs are available or what the log contains
