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 74) behind an x402 paywall. The provider operates a broad suite of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all settled on the Base network using USDC. Each call costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, subscriptions, or rate limits — just an x402-compatible payment header.
The specific endpoint `/api/v1/audit/logs/74` is listed under the provider's "Premium API Access" label. It accepts POST requests and returns JSON. However, the crawled documentation pages (docs, pricing, README) all rendered only a wallet-connect prompt with no further technical detail, so the exact request body schema and response structure are unknown. The provider's landing page confirms the $0.02 per-request pricing model and advertises instant access with no minimums or commitments.
Because this endpoint targets a single audit log resource (ID 74), its utility is narrow compared to the provider's broader catalog. Without documentation on what fields the audit log contains or what POST body parameters are accepted, callers will need to experiment or contact the provider for integration guidance.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and the documentation pages are empty beyond a wallet-connect prompt. The specific resource (audit log 74) is narrow and unexplained.
Warnings
- —No API documentation available — docs, pricing, and README pages all render only a wallet-connect prompt with no content.
- —The endpoint targets a single hardcoded audit log ID (74); unclear if other IDs are available or what the log contains.
- —No request body schema or response schema is documented; callers must experiment.
- —Provider appears to be a generic demo/showcase site with many $0.02 endpoints across unrelated domains — actual data quality is unverified.
