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 (report ID 46) 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 (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. The platform emphasizes no API keys, no rate limits, and instant access. However, this specific listing is for the compliance reports endpoint only.
Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no description of what the compliance report actually contains. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what data is returned or what input parameters are expected.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 per call in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no description of what the compliance report actually contains. This is effectively a stub listing.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README all return only 'Connect wallet' with no content.
- —No OpenAPI or schema definition found; request parameters and response format are unknown.
- —The nature of the 'compliance report' (report 46) is entirely undocumented — unclear what data is returned.
