Pay-per-call audit log access on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 44) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The endpoint is part of a broader platform hosted at lowpaymentfee.com that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced uniformly at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers simply attach an x402 payment header to each request.
Documentation is extremely sparse. 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 documentation, and no example payloads available. The specific purpose and schema of the audit logs endpoint cannot be confirmed beyond its URL path and the x402 challenge metadata. The endpoint is confirmed live (returns HTTP 402 with a valid x402 challenge).

Quality
The endpoint is confirmed live with a valid x402 challenge, but documentation is essentially nonexistent — all doc pages show only 'Connect wallet'. There is no OpenAPI spec, no request/response schema, and no examples. The purpose of 'audit/logs/44' is unclear beyond the URL path. This is effectively a stub listing.
Warnings
- —No documentation available — all doc/pricing/README pages render only 'Connect wallet'
- —No OpenAPI or request/response schema provided; input and output formats are unknown
- —The specific meaning of 'audit/logs/44' is unverifiable — it may be a demo or placeholder endpoint
- —Platform appears to list many endpoints at uniform $0.02 pricing but provides no substantive docs for any of them
