• Farming (staked tokens + rewards)
• Vesting / locked tokens

Each position includes USD value, APY (when available), and health factor for lending.

Filter by chain: GET /user/complex_protocol_list?id={address}&chain_id={chain}

NFT List

GET /user/all_nft_list?id={address}&is_all=true

Returns NFT holdings with collection name, floor price, and image.

Transaction History

GET /user/history_list?id={address}&chain_id={chain}&page_count=20

• Swap, Send, Receive, Approve, Contract Interaction
• Token amounts and counterparties
• Pagination via start_time parameter

Token Info

GET /token?id={address}&chain_id={chain}

Returns token metadata: name, symbol, price, market cap, holders, logo.

Protocol Info

GET /protocol?id={protocol_id}

Returns protocol details: TVL, chains, site URL, logo.

Protocol List

GET /protocol/list

Returns all tracked protocols. Large payload — filter output.

Usage Notes

• DeBank tracks 100+ EVM chains automatically — no need to query each chain separately when using all_* endpoints
• Always use all_token_list and all_complex_protocol_list for full portfolio overview
• For transaction history, chain_id is required — ask user which chain or iterate through their active chains
• DeFi positions include detailed breakdowns (supply vs borrow, LP composition) — present clearly
• Combine with coingecko for price charts and security-check for token risk assessment
• Rate limits depend on plan tier — avoid unnecessary repeated calls

Example Interactions

User: "What's in my wallet?" → Call all_token_list for active wallet, present holdings sorted by USD value

User: "Show my DeFi positions" → Call all_complex_protocol_list, group by protocol, show value and APY

User: "What's the portfolio of 0x...?" → Call total_balance for overview, then all_token_list for details

User: "Show my recent transactions on BSC" → Call history_list with chain_id=bsc, present last 20 parsed transactions
