Pay-per-call audit log access on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides premium API access to audit log data (specifically log ID 66) via the x402 payment protocol. It accepts POST requests and returns JSON responses. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 0.02 USDC per request (20,000 base units at 6 decimals).
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto market data, and infrastructure utilities — all priced at $0.02 per request. The platform requires no API keys, imposes no rate limits, and provides instant access. All endpoints use the x402 protocol for payment, settling on the Base L2 network.
This specific endpoint (/api/v1/audit/logs/66) appears to serve audit log records. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the audit log response contains or what parameters the POST body accepts. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation makes it difficult to use without experimentation.

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 schema, no request/response examples, and all documentation pages render only a wallet-connect prompt. The purpose of this specific audit-log endpoint is unclear beyond its URL path. Effectively a stub listing.
