## When to prefer this

Use this endpoint when you need a quick, real-time single-figure TVL for a specific DeFi protocol aggregated across all chains. Prefer the sibling 'TVL breakdown by chain' endpoint if you need per-chain or per-category breakdowns.

## Known failure modes

- Unknown or unsupported protocol name returns an error or empty result
- Protocol name ambiguity (e.g. multiple protocols with similar names) may return incorrect data
- Temporary data feed outages may result in stale or unavailable TVL figures
- Payment failure (insufficient USDC balance) blocks the request
