Lido TVL data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint returns Lido protocol Total Value Locked (TVL) data, accessible through the x402 payment protocol on the Base network. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering DeFi data, analytics, AI/ML inference, finance, crypto, and utility services.
The endpoint accepts POST requests and charges $0.02 per call, settled in USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). Payment is handled via the x402 exact-payment scheme — no API keys, accounts, or rate limits are required. The caller includes an X-PAYMENT header with a signed payment proof, and the server returns the data in application/json format. The maximum payment timeout is 300 seconds.
Documentation on the site is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no example request/response payloads, and no description of the response format for the Lido TVL endpoint specifically. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data shape returned after payment is unknown.
