Pay-per-call audit log endpoint 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 80) via an x402 payment challenge. 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/80` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals) to the payee address `0x1A2B...85F3` on Base. No API keys, rate limits, or upfront commitments are required — access is purely transactional.
Documentation on the site is extremely thin. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads 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 no examples. The actual data returned by this audit log endpoint is completely unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or output schema provided; the shape of the audit log response is unknown
- —The specific purpose of 'audit/logs/80' (what log ID 80 represents) is undocumented
- —The broader platform lists many endpoints but none have documented request/response formats
