Pay-per-call audit log access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 92) behind an x402 paywall. The provider operates a broad suite of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all settled on the Base network using USDC at a flat $0.02 per request.
The specific resource `/api/v1/audit/logs/92` is labeled "Premium API Access" and accepts POST requests. Payment is handled via the x402 protocol: callers must include an X-PAYMENT header with a valid payment proof. The endpoint charges up to 20,000 base units of USDC (0.02 USDC = $0.02) per call, paid to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. The payment timeout is 300 seconds.
Note that while the provider's landing page lists many API categories (analytics, AI, finance, geocoding, etc.), the specific endpoint being listed here is for audit logs. Documentation beyond the landing page 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 examples of what the audit log response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what data is actually returned.

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 documented request/response schema, no examples, and the docs pages are empty. The specific purpose of 'audit/logs/92' is unclear beyond the generic 'Premium API Access' label.
