StatusUnknown
Output
A JSON object containing the chain name, chain ID, chain type (e.g. Optimistic Rollup), active status, TVL in USD, gas prices (fast/standard/slow in gwei), finality period description, latest block (if available), block production status, response time in milliseconds, and a UTC timestamp of the query.
Example use cases
Example prompt
“Can you check the current health of the Base chain — I want to know its TVL, gas prices, block production status, and whether it's active right now?”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/chain/healthWhen to prefer
Use this endpoint when you need a quick, unified snapshot of a blockchain's health — combining TVL, gas, and block production into one call. Ideal for DeFi agents that need to decide whether a chain is suitable for a transaction, monitor network conditions before executing a swap or bridge, or surface infrastructure status to users. Prefer this over separate gas or TVL APIs when you need a holistic chain-level view in a single request.
Side effects
- Unsupported chain name returns error or empty response
- Chain temporarily unreachable results in degraded or null metrics
- latest_block may be null if chain indexer is unavailable
- Network timeout if upstream data provider is slow
- Invalid chain identifier returns validation error
