Pay-per-call audit log access 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 ID 87) via the x402 payment protocol. It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities. All endpoints on the platform share a uniform $0.02 per request pricing model, settled in USDC on the Base network.
The specific endpoint `/api/v1/audit/logs/87` is described as "Premium API Access" and accepts POST requests. Payment is handled via the x402 exact-payment scheme: callers attach an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The response MIME type is application/json. No API keys or rate limits are advertised; access is gated purely by per-call micropayment.
Documentation on the site is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual shape of the audit log data returned after payment is unknown.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the purpose of 'audit/logs/87' is entirely opaque. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body and response shape are completely unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no technical content
- —The specific purpose and data content of audit log ID 87 is undocumented
- —The endpoint path suggests a single fixed resource (/audit/logs/87) rather than a parameterized API
