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 entry #26 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 settled on the Base network using USDC.
The specific resource `/api/v1/audit/logs/26` is described by the provider as "Premium API Access" and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment on Base. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The payment recipient address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, and the payment timeout is 300 seconds.
The platform advertises a simple pricing model of $0.02 per request across all endpoints, with no API keys, no rate limits, no minimums, and instant access. However, documentation beyond the landing page is essentially empty (all subpages just show "Connect wallet"), so the exact schema of the audit log response, available query parameters, and the nature of the audit data itself are unknown. The endpoint is confirmed live — it returns a well-formed 402 challenge — but the lack of documentation limits confidence in what the response payload contains.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no documentation of request/response formats, and the audit log endpoint's purpose and data model are entirely opaque. All doc pages beyond the landing page are empty ('Connect wallet' only).
Warnings
- —No documentation available — all doc/pricing/API pages return only 'Connect wallet' with no content.
- —The exact structure of the audit log response is unknown; no output schema or example is provided.
- —The specific endpoint /api/v1/audit/logs/26 is not listed on the provider's landing page among advertised APIs, raising questions about its intended use.
- —The provider lists many endpoint categories (AI, finance, analytics, etc.) all at $0.02, but none have visible documentation — treat all with caution.
