Example prompt: Can you pull up the latest Aave Base cbETH headroom check from Tenjin — I want to know how much supply capacity is left against the cap and what the current reserve size looks like in USD?

## When to prefer this

Choose this endpoint when you need a curated, human-analyst-written snapshot of Aave Base cbETH supply cap utilization and reserve data, rather than querying raw on-chain or DeFiLlama APIs directly. Ideal for agents that want pre-interpreted DeFi market intelligence rather than raw data feeds.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- 404 if the handle or slug is incorrect
- Article may reflect a past snapshot rather than real-time on-chain data
- Rate limiting or temporary unavailability of the Tenjin API
