Tools as reported by the server

• assess_counterparty_risk
  Return a decision-ready counterparty-risk verdict for an EVM address before funds or authority are committed. The result branches to high_risk, caution, acceptable, or insufficient_data with the evidence needed for the calling agent to act. Use when: Delegate this check before sending funds, grantin
• assess_market_resolution
  Return a decision-ready resolution-risk verdict for one Polymarket market before an agent trades, quotes, or forecasts it. The result branches to tradeable, ambiguous, avoid, or insufficient_data and names the resolution basis (price_feed, official_source, media_consensus, unspecified), UMA dispute
• calculate
  Evaluate a safe arithmetic expression and return the numeric result. Supports +,-,*,/,**,%,sqrt,abs,round,floor,ceil,log,sin,cos,tan,pi,e. Use for derived figures (ratios, differences, percentages) that no tool output already provides. Use when: Use when an agent must derive a value that tool output
• convert_currency
  Convert an amount between fiat currencies (USD, EUR, GBP) and crypto assets (BTC, ETH, USDC, SOL) and return the converted amount plus the exchange rate used. Use when: Use when an amount must be expressed in a different currency than the source data — for example converting a USD portfolio value in
• decode_transaction
  Decode a transaction's calldata into a human-readable function name and arguments, and return transaction status (1=success, 0=revert), gas used, and block number. Uses a supplied ABI when provided, otherwise 4byte.directory. Supports Ethereum mainnet and Base. Use when: Use when one known transacti
• delegate_to_agent
  Delegate a task to a remote A2A-compliant agent: discover its capabilities via its agent card, send it a message, handle payment, and return the result. Use only when no local platform tool can fulfil the request. Use when: Use when a task requires specialist capabilities beyond the local tool set.
• discover_agents
  Find opt-in remote A2A agents, published tool capabilities, endpoints, and public reputation status. Use when: Use before delegate_to_agent when a specialist agent is needed but its URL is unknown. Limitations: Discovery is read-only and does not add an agent to the org allowlist; delegate_to_agent
• get_datetime
  Return the current UTC date and time as a formatted string and ISO 8601 timestamp, for grounding time-relative reasoning in the actual clock rather than training-data assumptions. Use when: Use when a task must anchor on the current date or time — computing ages, windows, deadlines, or 'as of today'
• get_block
  Get block details (timestamp, gas used, base fee, miner, transaction count) for an Ethereum or Base block by number, hash, or 'latest'. Use to anchor events to a point in chain time. Use when: Use when a question depends on when a block occurred, how full it was, or its base fee — for example dating
• get_chain_metrics
  Compare blockchain ecosystem health via DeFiLlama: current TVL, 7/30-day TVL change, and aggregate fee activity. Pass chains such as ['Ethereum', 'Arbitrum', 'Solana'] for a focused comparison, or omit chains to inspect the highest-TVL ecosystems. Use when: Use for ecosystem-level comparisons — whic
• get_dex_quote
  Get the best Uniswap v3 swap quote on Ethereum (chain_id=1) or Base (chain_id=8453) via direct on-chain QuoterV2 calls. Queries all four fee tiers (100/500/3000/10000 bps) in parallel and returns the tier with the highest output amount, along with per-tier breakdown. Inputs are raw uint256 amounts a
• get_dex_volume
  Compare decentralized exchange activity via DeFiLlama: 24h/7d/30-day volume, period-over-period changes, and each protocol's share of reported global 24-hour DEX volume. Filter by protocol and rank by a 1-, 7-, or 30-day lookback window. Use when: Use for landscape questions — which DEXs dominate vo

  Block-accurate DeFi positions for a wallet across Aave v3, Compound v3, Uniswap v3 LP, and Lido on Ethereum or Base. Returns Aave account health (collateral, debt, health factor, LTV) with per-reserve breakdown, Compound v3 market positions, Uniswap v3 LP positions by token ID, and on Ethereum the L

• get_liquidation_risk
  Assess DeFi liquidation risk for up to 50 wallets across Aave v3 and Compound v3 on Ethereum or Base. Returns per-wallet health factor, tiered risk classification (liquidatable, critical, warning, caution, healthy, no_debt), and an overall_tier aggregate. Per-protocol failures are isolated — one pro
• get_token_approvals
  Block-accurate audit of ERC-20 allowances for a wallet across curated DeFi spenders (Uniswap, Aave, Compound, 1inch, 0x, OpenSea) on Ethereum or Base. Flags unlimited approvals by risk level (high=unknown spender, medium=trusted protocol, low=bounded). Use before swaps or after security incidents to
• get_wallet_approvals
  Inspect a wallet's current ERC-20 token authorization exposure on one DeBank-supported chain. Returns discovered spenders, USD exposure, protocol attribution, and hacked or abandoned protocol flags. This is broader than the curated block-accurate get_token_approvals tool. Use when: Use when broad sp
• get_token_price
  Get current price, 24h change, market cap, FDV, and volume for one or more crypto tokens. Accepts ticker symbols, full names, or CoinGecko IDs; unknown symbols resolve automatically. Batch up to 50 tokens. Reuse price_usd/value_usd already returned by get_wallet_portfolio instead of re-calling. Use
• get_protocol_tvl
  Get Total Value Locked for one or many DeFi protocols from DeFiLlama: current USD TVL, 7/30-day change, fees and revenue when reported, per-chain breakdown, and optional daily historical series. Batch multiple protocols via protocols=[...] — batch responses return one compact economic summary per pr
• get_token_price_historical
  Get historical crypto prices over a 1–365 day window: period statistics (start, end, % change, high, low), a downsampled daily series, high_30d, std_30d, and dca_baseline_90d. Use for period comparisons and trend analysis; prefer over web_search for time-comparative financial queries. Pass stats_onl

Returns up to 50 pools. For protocol-specific lending comparisons (Aave vs Com
• web_search
  Real-time web search via Tavily for current events, fact-checking, and research.

Use when: Choose when the task needs current, external, or factual informa
• count_text_stats
  Return word, character, sentence, and paragraph counts plus average words per sentence for a given text, for length checks and content sizing decisions.

• get_eth_balance
  Get the exact on-chain native ETH balance of an address on Ethereum or Base, in wei and ether. get_wallet_portfolio already includes native ETH in its holdings — call this only for a standalone balance without a portfolio scan.
