x402-gated compliance report endpoint on Base, pay-per-call with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific compliance report (ID 67) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals).
The broader lowpaymentfee.com platform advertises a suite of pay-per-request APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto market data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific listing is for the compliance reports endpoint (`/api/v1/compliance/reports/67`), which is not listed on the provider's public landing page among the advertised API categories. Its exact response payload and the nature of the "compliance report" it returns are undocumented.
The endpoint is live: the probe received a proper HTTP 402 challenge with a well-formed x402 v1 payment envelope. Documentation on the site 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 request/response schema beyond the x402 outputSchema stub, and no description of what the compliance report contains.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI spec, no request/response schema, and the specific compliance report endpoint is not even listed among the provider's advertised APIs. The nature of the returned data is entirely unknown.
