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 73) via the x402 payment protocol. The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme to the specified wallet address, with no API keys or rate limits required.
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 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request and settle on the Base network using USDC. However, the specific endpoint being listed here — `/api/v1/audit/logs/73` — is not documented on the site's landing page among the advertised API categories, so its exact response schema and data content are unclear.
The site's documentation, pricing, and API pages all appear to be stub pages showing only a "Connect wallet" prompt, offering no additional technical detail about request/response formats or endpoint behavior. Without an OpenAPI spec, example responses, or detailed docs, the actual output of this audit logs endpoint remains uncertain.
