Read the appropriate file for detailed parameters, response formats, and examples:
- Balances (portfolio, holdings, USD values): See references/balances.md
- History (wallet tx history, P&L, tax reports): See references/history.md
- Transfers (sent/received, payment tracking): See references/transfers.md
- Identity (wallet labels, exchange detection): See references/identity.md
- Funded By (funding source, sybil detection): See references/funded-by.md

Implementation Notes
- Use
curlorfetch— no SDK required - All endpoints return JSON
- Pagination: use
pageparam (balances) orbefore/cursor (history, transfers) - Default limit: 100 per request
- Wallet API requests cost 100 credits each
- Identity returns 404 for unknown wallets — handle gracefully
- Funded By returns 404 if wallet never received SOL
- Enhanced Transactions uses a different base URL (
api-mainnet.helius-rpc.com)
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install helius-api - After installation, invoke the skill by name or use
/helius-api - Provide required inputs per the skill's parameter spec and get structured output
