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 55) via an x402 payment-gated API. The endpoint 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; access is granted immediately upon valid x402 payment.
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, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request. However, this specific listing covers only the `/api/v1/audit/logs/55` endpoint.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data returned after payment is unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is zero documentation on request parameters, response schema, or what 'audit/logs/55' actually returns. The docs pages are empty stubs. Without any OpenAPI spec, examples, or meaningful documentation, this is effectively a stub listing.
Warnings
- —No OpenAPI spec or request/response schema available
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —The specific data returned by /api/v1/audit/logs/55 after payment is completely unknown
- —The '55' in the path suggests a specific resource ID but there is no documentation on valid IDs or how to discover them
- —Platform appears to be a generic demo or placeholder — many diverse endpoints all at identical pricing with no substantive docs
