x402-gated compliance reports endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a compliance report resource (report ID 99) via the x402 payment protocol. The endpoint is live and returns a 402 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, rate limits, or subscriptions required — callers simply attach an X-PAYMENT header with a valid payment proof.
The broader lowpaymentfee.com platform advertises a suite of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request. However, the specific endpoint being listed here — `/api/v1/compliance/reports/99` — is not explicitly described on the site's landing page, so its exact response payload and purpose are unclear. The description "Premium API Access" is the only label provided in the x402 challenge.
Documentation is extremely thin: the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no example request/response, and no schema describing what a compliance report contains. The endpoint accepts POST requests and returns application/json according to the x402 challenge metadata.

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 example request/response, and the specific compliance report endpoint is not even listed on the provider's landing page. The purpose and schema of the response are unknown.
