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 entry 28) through 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). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request. However, this specific listing covers only the `/api/v1/audit/logs/28` resource. The platform advertises no minimums, no commitments, and instant access.
Documentation is extremely sparse. The docs, API, pricing, 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 exact structure of the audit log response is unknown. The endpoint is confirmed live via a 402 challenge captured during probing.

Quality
The endpoint is confirmed live via a valid 402 challenge, but there is zero documentation on request format, response schema, or what audit log data is actually returned. The docs/pricing/README pages are all empty beyond a wallet connect prompt. The endpoint path suggests a single fixed resource (/logs/28) with unclear utility. Effectively a stub listing.
Warnings
- —No OpenAPI spec or schema documentation available
- —All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content
- —The endpoint targets a specific log entry (/logs/28) — unclear if other log IDs are available or what data is returned
- —Response format and fields are completely unknown
- —Platform appears to be a demonstration or early-stage project with many listed endpoints but no substantive documentation
