Output
Returns a JSON object containing the protocol's total TVL (in USD), a breakdown of TVL per supported chain, the protocol's DeFi category (e.g. lending, DEX, liquid staking), the list of chains it operates on, and its market capitalization.
Example use cases
Portfolio DeFi exposure check
“I have some funds in Aave — can you pull the latest TVL, which chains it runs on, and its market cap so I can gauge how healthy the protocol is?”
Compare DeFi protocol scale
“Look up the TVL and chain breakdown for Uniswap — I want to see how much liquidity is on each chain and what category it falls under.”
Research new DeFi investment
“I'm looking at Pendle Finance as a potential yield investment — what's its total TVL, supported chains, and market cap right now?”
Technical details
Endpoint
POSThttps://api.x-402.online/v1/defi/protocolWhen to prefer
Use this endpoint when you need structured TVL and metadata for a specific known DeFi protocol by slug, especially when you need per-chain TVL breakdown alongside category and market cap in a single call. Prefer this over general crypto market endpoints when the query is specifically about protocol-level DeFi metrics rather than token prices or yield opportunities.
Side effects
- Unknown or misspelled protocol slug returns an error or empty result
- Protocol slug format mismatch (e.g. using display name instead of slug)
- Data may be slightly delayed if the upstream TVL provider hasn't refreshed recently
- Network or payment failure results in HTTP 402 or 5xx response
