Pay-per-call audit log retrieval on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to audit log data (specifically log ID 98) 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) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required — access is granted purely through the x402 payment protocol.
The broader lowpaymentfee.com platform hosts a variety 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). All endpoints are uniformly priced at $0.02 per request and use the same x402 payment mechanism on Base.
Documentation on the site is extremely sparse — the docs, pricing, API, and README 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 usage examples available. The specific behavior and response format of the /api/v1/audit/logs/98 endpoint must be inferred entirely from the x402 challenge metadata, which confirms it is live and accepting POST requests with JSON output.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The docs pages are empty stubs. The specific purpose of 'audit/logs/98' is opaque — it's unclear what data is returned or what input is expected beyond a POST request.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —The specific endpoint /api/v1/audit/logs/98 has a hardcoded log ID; unclear if this is parameterized or a fixed resource
- —No examples of actual response payloads exist in crawled material
