x402-gated compliance report endpoint on Base, pay-per-call with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a compliance report (resource ID 37) via the x402 payment protocol. The endpoint is live and returns a standard x402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme with no API keys, subscriptions, or rate limits required.
The parent site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto market data, and infrastructure utilities. All endpoints appear to share the same $0.02/request pricing model settled in USDC on Base. However, this specific endpoint (/api/v1/compliance/reports/37) is not listed on the site's landing page among the advertised API categories, so its exact response payload and purpose are unclear. The description in the x402 challenge is simply "Premium API Access" with a JSON MIME type.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema beyond the x402 outputSchema stub, and no examples of what the compliance report contains. Prospective callers should be aware that the actual data returned is undocumented.

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 examples, and the specific compliance report endpoint is not even listed on the provider's own landing page. The actual data returned is completely unknown.
