Pay-per-call audit log retrieval 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 #25) 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/25` is labeled "Premium API Access" and accepts POST requests. Payment is handled inline: callers receive a 402 challenge containing the USDC asset address on Base (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) and a payTo wallet. The maxAmountRequired is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys are needed; authentication is replaced by the x402 micropayment header. The platform advertises no rate limits and instant access.
Documentation is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no description of what the audit log data actually contains. The endpoint is live (402 challenge confirmed), but the lack of documentation makes it difficult to know what payload to send or what response to expect.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and network. However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page listing, and the specific purpose of 'audit/logs/25' is unexplained. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no useful content
- —The specific meaning of 'audit/logs/25' is not documented; it is unclear what data is returned
- —The endpoint path references a specific log ID (25), which may not generalize to other IDs without further info
