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 70) 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 endpoint `/api/v1/audit/logs/70` is labeled "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 per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. There are no API keys, no rate limits, and no subscription commitments — each request is independently paid.
The platform advertises a uniform $0.02/request pricing across all its endpoints. Documentation pages exist at /docs, /pricing, and /api but currently render only a "Connect wallet" prompt with no additional technical detail. No OpenAPI schema, request/response examples, or detailed endpoint documentation were found during the crawl. The actual data returned by the audit logs endpoint is unknown beyond the stated mime type of application/json.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only a wallet-connect prompt. The purpose of 'audit/logs/70' is unclear beyond the generic 'Premium API Access' label, making this effectively a stub listing.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README all render only 'Connect wallet' with no technical content.
- —The specific data returned by /api/v1/audit/logs/70 is undocumented; 'Premium API Access' is a generic label.
- —No OpenAPI or JSON schema describing request parameters or response format.
- —This endpoint path references a specific log ID (70); it is unclear whether other IDs are available or what the log contains.
