## Tools (as reported by the server, not verified)

- `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
- `get\_defi\_positions`: 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\_gas\_price`: Get current EIP-1559 gas fees on Ethereum or Base: base fee, priority fee, next-block base fee estimate, and congestion \(gas\_used\_ratio \>0.5 busy, \>0.9 very congested\). Optional USD estimates cover a simple transfer and a swap-like transaction. Cached 10 seconds per chain. Use when: Use before advis
- `get\_lending\_rates`: Get current on-chain lending supply/borrow APYs for Aave v3 reserves and Compound v3 markets on Ethereum or Base, with per-asset snapshots and Compound utilization. Use for protocol-specific yield comparisons such as USDC on Aave vs Compound. Use when: Use for protocol-specific lending-rate question
- `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
- `get\_yield\_rates`: Get DeFi yield pool rates from DeFiLlama across 1,000+ protocols and all chains: pools sorted by APY with TVL, base/reward APY, and 7d/30d mean APY context, filterable by protocol, chain, min TVL, min/max APY, and symbol. 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 search\_depth='advanced' for complex queries \(higher quality, higher cost\) and topic='news' or 'finance' for headlines or market information. 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. Use when: Use when output length must be validated or reported — e.g. verifying a summary meets a length contract or comparing document sizes. Do n
- `http\_fetch`: Fetch a web page and return its main text content, cleaned of markup. Use to read articles, documentation, and other resources referenced by URL. Blocks private and cloud-metadata addresses and re-validates every redirect hop. Use when: Use when a known URL's content is needed and structured tools c
- `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. Use when: Use when a wallet's gas-availability or standalone ETH amount
- `get\_erc20\_balance`: Get the exact on-chain ERC-20 balance of a wallet for one token contract, normalized by decimals and returned with the token's symbol. Use for a precise single-token check. Use when: Use when a specific token contract's balance must be verified block-accurately — e.g. confirming funds before an appr

Use when: Use for wallet activity discovery
- `get\_wallet\_positions`: Get a wallet's DeFi positions across all DeBank-supported chains and protocols. Returns protocol-level positions, asset/debt/net USD values, optional token lists, aggregate exposure, and optional all-chain net worth. Set include\_token\_balances=true to also return DeBank's complete cross-chain wallet
- `read\_contract`: Call any view/pure function on a smart contract and return the decoded result, using a supplied ABI fragment. Supports historical reads via block\_identifier and caller\_address context for msg.sender-dependent views. Read-only: state-changing functions are rejected. Use when: Use when a protocol ques
- `record\_predictions`: Record a complete structured prediction document for downstream evaluation. Call once with the exact machine-readable prediction; the human-readable report is provided separately. Use when: Use at the end of a scheduled analysis run to persist the machine-readable prediction for later scoring. Call
- `resolve\_ens`: Resolve an ENS name \(e.g. 'vitalik.eth'\) to an Ethereum address, or an address to its primary ENS name, with avatar text record when available. Mainnet only. Use when: Use only when no 0x address is available and a name must become an address \(or vice versa for attribution\). If a 0x address is alrea
- `validate\_opportunity`: Return a decision-ready yield-opportunity verdict before capital is deployed. The result branches to sustainable, caution, unsustainable, or insufficient\_data and gives the calling agent the evidence needed to proceed, pause, or reject the opportunity.
