ask_model

Ask another AI model (GPT, Gemini, Grok and others) one question through keyfo and get its answer, for a second opinion. This is a paid model call: it needs a key and draws from the key’s daily allowance at the model’s price. A trial key can ask low-cost models only. The other model gets no tools.

Argument	Type	Description
model	string	Model ID with its vendor, like x-ai/grok-4.3 or google/gemini-2.5-flash. Empty uses a low-cost default model.
prompt*	string	The question for the other model, with all the context it needs: it does not see this conversation.
system	string	Optional instructions for the other model.
max_tokens	integer	Longest answer in tokens, from 1 to 2048. 512 by default; a trial key gets 512 at most.

build_morpho_deposit

Build unsigned transactions to deposit USDG into a Morpho vault on Robinhood Chain, or to withdraw it. Without a vault, the largest USDG vault is used. Vaults carry smart contract, curator and market risk. Returns calls for the wallet owner to sign and send in order on Robinhood Chain (chain ID 4663). No keyfo tool signs. The answer also has sign_url: a keyfo page where the user checks the transaction and signs it in their own wallet. It stays open for 15 minutes and gets a new quote itself when the price is out of date. Show that link to the user, and never ask them to paste the transaction data anywhere.

read-only

Argument	Type	Description
pct	number	Share to move: of the wallet’s USDG for a deposit, of its vault shares for a withdrawal. Above 0, up to 100.
usd	number	USDG to deposit or withdraw (1 USDG is about $1). Use this or pct.
side	string	deposit or withdraw. deposit by default.
vault	string	Vault address or name from morpho_rates. Empty uses the largest USDG vault.
wallet*	string	The wallet that signs and sends, and holds the USDG or the vault shares.

build_revoke

Build an unsigned transaction that sets a token approval back to zero, so that spender can no longer move the token. Needs a key. Returns a call for the wallet owner to sign and send on Robinhood Chain (chain ID 4663). No keyfo tool signs. The answer also has sign_url: a keyfo page where the user checks the transaction and signs it in their own wallet. It stays open for 15 minutes and gets a new quote itself when the price is out of date. Show that link to the user, and never ask them to paste the transaction data anywhere.

read-only

Argument	Type	Description

wallet*	string	The wallet that gave the approval. It signs and sends.
spender*	string	Address the approval was given to, from stock_approvals.

}

build_trade

Build unsigned transactions to buy a stock token on Robinhood Chain with ETH (`eth`, or `usd` worth of ETH) or sell `pct` percent of the wallet’s holding for ETH. `token` is a ticker (TSLA) or the token address. A buy needs the ETH, plus gas, already in `wallet`; if it is short, fund it with fund_agent first. The calls expire at valid_until: sign and send before then, or build the trade again. Returns calls for the wallet owner to sign and send in order on Robinhood Chain (chain ID 4663). No keyfo tool signs. The answer also has sign_url: a keyfo page where the user checks the transaction and signs it in their own wallet. It stays open for 15 minutes and gets a new quote itself when the price is out of date. Show that link to the user, and never ask them to paste the transaction data anywhere.

read-only

Argument	Type	Description
eth	number	ETH to spend on a buy, up to 10.
pct	number	Share of the holding to sell, above 0 and up to 100.
usd	number	Dollars of ETH to spend, at the current ETH price.
side*	string	buy or sell.
token*	string	Ticker, like TSLA, or the token address.
wallet*	string	The wallet that signs and sends. The route is quoted for it.

buy_at_price

Plan a buy of a stock token on Robinhood Chain for `wallet` that waits for a price: when the pool price goes `trigger` below or above `price_usd`, keyfo prepares a buy of `usd` or `eth` and a sign link. Nothing is bought or signed now. The plan starts after the wallet’s owner confirms it at https://keyfo.xyz/app. The price is the pool’s 5-minute median from at least 5 samples, and the level must hold for about 3 minutes. Only pools with at least $250000 of depth qualify, and no buy is prepared if the route costs more than 3% above the median. The owner then has 6 hours to sign. It is not a limit order: the buy goes at the market price when it is signed. One time by default; with `repeat`, it waits again after each buy. Limits as for scheduled buys: 5 plans per wallet, $500 per buy, $1000 a week.

Argument	Type	Description
eth	number	ETH to spend on the buy. Give usd or eth, not both.
usd	number	Dollars of ETH to spend on the buy, at the ETH price when it is prepared. Up to 500.
token*	string	Ticker, like NVDA, or the token address.
repeat	boolean	true waits for the price again after each buy. Default: false, one buy.
wallet*	string	The wallet that buys and signs. Its owner confirms the plan at https://keyfo.xyz/app.
trigger*	string	below or above: buy when the pool price drops below or rises above price_usd.

cancel_schedule

Cancel a buy plan by its `id`. Nothing new is prepared for it; buys already signed stay as they are.

Argument	Type	Description
id*	string	The plan id from schedule_buy or list_schedules.

fund_agent

Quote moving funds from another network (ethereum, base, arbitrum, optimism, bnb, polygon and others, 15 in all, or a chain ID) to an agent wallet on Robinhood Chain, arriving as ETH. `payer` is the wallet that already holds the funds on the origin network: if the user did not name it, ask, do not reuse `wallet`. `amount` is in the smallest unit (wei for ETH), a number or a string of digits. Returns transactions for the payer to sign. The answer also has sign_url: a keyfo page where the user checks the transaction and signs it in their own wallet. It stays open for 15 minutes and gets a new quote itself when the price is out of date. Show that link to the user, and never ask them to paste the transaction data anywhere.

read-only

Argument	Type	Description
payer*	string	Wallet that pays on the origin network and signs there. It must hold the funds there, so it is usually not the agent wallet: ask the user for it, do not copy `wallet`.
amount*	any	Amount in the smallest unit of what you pay with, like wei for ETH.
wallet*	string	Agent wallet on Robinhood Chain that receives the ETH.
currency	string	Token address to pay with on the origin network. Empty pays in its native coin.

portfolio_pnl

Profit and loss for the stock tokens a wallet holds on Robinhood Chain, read only, no key needed: average entry price, unrealized P&L per token and in total. Entry prices come from the wallet’s buys in its transfer history on the chain. Tokens that arrived without a payment have no known cost and are left out of the average. Where the ETH price at the buy’s block is not known, the current one is used and the result is marked approximate. Gas is not counted, sales for ETH show their proceeds only when they went through LI.FI or OKX, and a swap from one stock token to another has no entry price.

schedule_buy
