COMP liquidity data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the COMP (Compound) token. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol on the Base network, settling in USDC.
The specific endpoint `/api/v1/defi/COMP/liquidity` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a maximum cost of 20,000 base units of USDC (0.02 USD) per call. No API keys or accounts are required — callers authenticate solely via the x402 payment header. The provider advertises no rate limits and instant access.
Documentation beyond the landing page 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 schema, no example request/response payloads, and no detailed description of what fields the liquidity response contains. The endpoint is confirmed live (402 challenge captured), but the actual data quality and response format remain unknown.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no example request or response, and all documentation pages are empty stubs. The actual response format and data content are entirely unknown, making this effectively a stub listing.
