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

- `parse\_intent`: Parse a plain-English swap request \(e.g. "swap 100 USDC for ETH on Optimism"\) into a structured intent: \{ intent: "swap"\|"unknown", entities: \[\{type: sellToken\|buyToken\|amount\|chain, value, raw\}\] \}. Backed by the live Ophis parser.
- `get\_quote`: Fetch a best-execution quote from the chain's Ophis orderbook \(use a chainId from list\_chains' \`tradeable\`\). Amounts are in atoms \(smallest unit, uint256 decimal string\). For kind='sell' the amount is the sell amount before fee; for kind='buy' it is the desired buy amount. Returns the orderbook quot
- `build\_order`: Build a bounded, ready-to-sign CoW order on Ophis. Returns \{ order, signing:\{domain,types,primaryType\}, fullAppData, appDataHash, partnerFee, next \}. The receiver is ALWAYS PINNED to the owner \(proceeds cannot leave the account\); this public endpoint exposes no custom-receiver option. Uses the corre
- `submit\_order`: Relay a pre-signed order to the chain's Ophis orderbook. Pass the exact \`order\` object and \`fullAppData\` from build\_order, plus your EIP-712 \`signature\` and \`from\` \(owner\). Returns the order UID on success and enrolls the owner for indexing, referral attribution, and trade rewards.
- `get\_integrator\_earnings`: Look up routed volume, the Ophis base fee, and the integrator's own fee on CoW-hosted chains, by appCode \(your widget appCode or SDK ophisReferrer code\). Routed volume is reported in USD, split by chain and by Ophis-operated versus CoW-hosted chains. Read-only, keyless, cumulative.
- `list\_chains`: List configured EVM orderbook chains, split into \`tradeable\` \(orderbook URL configured; only route get\_quote/build\_order to these\) and \`paused\` \(no configured orderbook URL, so those tools reject the chain\). This is configuration, not a live health or liquidity check. The standalone app's externally
- `get\_balances`: Read a wallet's native-token balance plus ERC-20 balances for the given token addresses on one chain, via a public RPC \(one multicall\). Returns each token's symbol, decimals, raw atoms, and human-readable amount. A token address that is not an ERC-20 is reported with an \`error\` and does not fail the
- `get\_portfolio`: Read a wallet's native and \(optionally\) ERC-20 balances across multiple chains at once. Pass tokensByChain \(chainId -\> token addresses\) to include token balances; omit chainIds to scan every chain with a public RPC \(max 13 chains, and at most 100 token reads total across all chains\). Per-chain RPC f
- `get\_gas`: Read a chain's current gas price \(EIP-1559 maxFee/maxPriority suggestion when supported, plus an effective gasPrice in wei and gwei\). Ophis trades are gasless for the trader, so this mainly bounds the cost of a one-time ERC-20 approval to the VaultRelayer. Read-only.
- `get\_token\_chart`: Fetch OHLCV price history for a token from the keyless GeckoTerminal market API \(resolves the token's deepest pool, then returns candles\). Use for an agent to reason about recent price action before quoting. Prices come from a single pool that may be thin or manipulated, so treat them as advisory, n
- `expected\_surplus`: Estimate how much better Ophis quotes than the open market for a sell: fetches the Ophis orderbook sell-quote and a public all-DEX aggregator \(KyberSwap\) quote for the same input, and returns \`beatBps\` \(+ = Ophis returns more of the buy token\). Use before build\_order to show the expected edge. The r
- `resolve\_token`: Resolve an ERC-20 token SYMBOL to its CANONICAL on-chain address from the trusted Ophis token list \(the same curated list the swap UI uses\). Use this BEFORE quoting or building so you never trade an address taken from chat, the web, or memory: a token can spoof the symbol "USDC" at a scam address, a
- `validate\_order`: Offline preflight for an order you built OUTSIDE build\_order \(no network call, no keys\). Catches the documented silent-failure modes before you sign or submit: wrong appCode \(prevents Ophis referral attribution\), wrong orderbook host \(api.cow.fi silently bypasses the Ophis stack on Ophis-operated ch
