## When to prefer this

Use this endpoint when you specifically need TVL data for the Balancer protocol sourced from DefiLlama. Prefer this over generic DeFi data APIs when you want a single focused lookup for Balancer without needing to parse a large multi-protocol response.

## Known failure modes

- DefiLlama upstream unavailable — returns an error or empty response
- Payment not included or insufficient — returns HTTP 402
- Balancer TVL data temporarily stale or missing from DefiLlama index
- Network timeout if DefiLlama API is slow to respond
