How this service works
Deep dive on any DeFi protocol by its DefiLlama slug (aave-v3, lido, uniswap…): current Total Value Locked, market cap, category, the chains it spans, a per-chain TVL breakdown, and a 30-day TVL history. Everything you need to size up a protocol in one call. Sourced from DefiLlama.
Output
A JSON object containing the protocol's name, symbol, category, current total TVL in USD, market cap in USD, an array of supported chain names, a per-chain TVL breakdown (array of {chain, tvlUsd} objects), and a 30-day TVL history (array of {date, tvlUsd} timestamped data points). Data is sourced from DefiLlama.
Example use cases
Example prompt
“Can you pull up Lido's current TVL, market cap, which chains it runs on, the per-chain TVL breakdown, and its 30-day TVL history from DefiLlama?”
Technical details
Endpoint
GEThttps://crypto.apitoll.cloud/v1/crypto/protocolWhen to prefer
Use this endpoint when you need a comprehensive, single-call snapshot of a specific DeFi protocol including TVL, market cap, multi-chain presence, and historical TVL trend. Prefer this over generic crypto price endpoints when the user wants DeFi-specific metrics like TVL or chain distribution. Ideal for protocol due diligence, DeFi research, or building dashboards that track on-chain liquidity depth.
Side effects
- Invalid or unknown protocol slug returns an error or empty result — verify the exact DefiLlama slug (e.g. 'aave-v3' not 'aave')
- Protocol may have been delisted or renamed on DefiLlama, causing a 404 or empty response
- Missing 'protocol' query param defaults to aave-v3, which may not be the intended protocol
- TVL data may lag by minutes if DefiLlama's upstream indexers are delayed
- Network or payment authorization failure (x402) may prevent the call from completing
