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 entry 68) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers authenticate purely via the x402 payment header.
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 usage examples. The specific purpose and schema of the audit logs endpoint is not documented beyond its URL path and the generic "Premium API Access" label. Prospective users should expect to experiment or contact the provider for details on what data this endpoint actually returns.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no response schema, and no examples. The audit logs endpoint purpose is entirely opaque beyond its URL path. This is effectively a stub listing.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README all render only 'Connect wallet' with no content
- —No OpenAPI or schema definition for request or response payloads
- —The specific data returned by /api/v1/audit/logs/68 is undocumented; 'Premium API Access' is a generic label applied across the platform
- —Cannot verify what audit log data is actually served or whether the endpoint returns meaningful results after payment
