Choose this endpoint when you need quick, cheap ($0.01 USDC) access to DeFi TVL data without signing up for a dedicated analytics service. Ideal for AI agents that already use GlianaAI's x402 payment rail and want to enrich DeFi research or monitoring workflows alongside other GlianaAI capabilities like LLM chat or market data in a single integrated platform.

## Known failure modes

- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Upstream DeFi data provider unavailable — may return 503 or stale data
- Malformed request body — returns 400 with schema validation error
- Rate limiting if prepaid balance is exhausted
