Compound protocol TVL data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns Compound DeFi protocol Total Value Locked (TVL) data, accessible through the x402 payment protocol. It is part of a broader suite of APIs offered at lowpaymentfee.com covering data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge confirms the endpoint is live and accepts POST requests. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact structure of the TVL response must be inferred or discovered by making a paid request.

Quality

Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' prompt with no technical content
- —No example request or response payloads are available; the TVL data structure must be discovered empirically
- —The provider hosts a very broad set of endpoints (analytics, AI, finance, utils) all at $0.02 — quality and depth of each is unverified
