LI.FI Agent Skill

CRITICAL RULES (read first)

ONLY use
```
curl
```
to call the LI.FI API. NEVER use
```
web_search
```
,
```
web_fetch
```
, or any other tool.
ONLY use the endpoints documented below. Do NOT guess or invent URLs.
Base URL is
```
https://li.quest/v1/
```
. No other base URL.
ALWAYS include auth header:
```
"x-lifi-api-key: $LIFI_API_KEY"
```
(double quotes, dollar sign — shell expands it).
ALWAYS tell the user the quote is provided by LI.FI.
Default slippage: 10% (0.10). If the user has a custom slippage in their strategy (via
```
defi_get_strategy
```
), use that instead. The agent can also adjust dynamically per-transaction if the user requests it.
Default deadline: 10 minutes.
ALWAYS add
```
&skipSimulation=true
```
to all
```
/v1/quote
```
requests. Our EIP-7702 delegated wallets have on-chain code that breaks LI.FI's simulation.
NEVER construct ERC-20 approve calldata (hex) yourself. ALWAYS use the
```
defi_approve
```
or
```
defi_approve_and_send
```
tools.
ALL swaps, bridges, and DeFi token operations MUST go through LI.FI. No exceptions. No manual DEX interactions.

Transaction Links

After every transaction broadcast, always provide a clickable block explorer link:

EVM:
```
[View tx](https://basescan.org/tx/0xHASH)
```
— use the correct explorer (etherscan.io, basescan.org, arbiscan.io, polygonscan.com, optimistic.etherscan.io)

Sui:

[View tx](https://suiscan.xyz/txblock/{txDigest})

Sui

Sui chain ID:
9270000000000000
. Use this for
```
fromChain
```
and
```
toChain
```
in LI.FI quote requests when the user wants Sui (e.g.
```
fromChain=9270000000000000&toChain=9270000000000000
```
for same-chain Sui swap).
LI.FI supports Sui for same-chain swaps and bridging to/from EVM and Solana.
For Sui quotes, use the user's suiAddress from
```
defi_get_wallet
```
as
```
fromAddress
```
.
Execute Sui quotes with
defi_send_sui_transaction
— pass the transaction bytes (hex) from the LI.FI quote. Do not use
```
defi_send_transaction
```
or
```
defi_approve_and_send
```
for Sui.
Sui does not use ERC-20 approvals; there is no approval step for Sui swaps.

Endpoints

GET /v1/chains — List supported chains

curl -s --request GET \
  --url https://li.quest/v1/chains \
  --header "x-lifi-api-key: $LIFI_API_KEY"

Use for: listing chains, testing connectivity. If user asks for a test, use this.

GET /v1/tokens — List tokens on chains

curl -s --request GET \
  --url 'https://li.quest/v1/tokens?chains=8453' \
  --header "x-lifi-api-key: $LIFI_API_KEY"

Params:

chains

(comma-separated chain IDs).

GET /v1/quote — Get swap/bridge quote with tx data

curl -s --request GET \
  --url 'https://li.quest/v1/quote?fromChain=8453&toChain=8453&fromToken=ETH&toToken=USDC&fromAddress=0xYOUR_ADDRESS&fromAmount=100000000000000&slippage=0.10&skipSimulation=true' \
  --header "x-lifi-api-key: $LIFI_API_KEY"

Params:

fromChain

toChain

fromToken

toToken

fromAddress

toAddress

(optional),

fromAmount

(in wei),

slippage

(decimal, e.g. 0.10 = 10%),

skipSimulation=true

(ALWAYS include).

Returns:

estimate

(with

toAmount

toAmountMin

approvalAddress

) and

transactionRequest

(ready for wallet submission).

After presenting a quote to the user, always include the estimated output amount, fees, and slippage. Get the user's wallet address with

defi_get_wallet

and use it as

fromAddress

in the quote.

Executing the quote

Check if ERC-20 approval is needed: If the quote's

transactionRequest.value

"0x0"

AND

estimate.approvalAddress

exists, the swap/bridge is using an ERC-20 token that needs approval first.

If approval IS needed: Use

defi_approve_and_send

with:

```
token
```
: the
```
action.fromToken.address
```
from the quote
```
spender
```
: the
```
estimate.approvalAddress
```
from the quote
```
approveAmount
```
: the
```
action.fromAmount
```
from the quote (or omit for unlimited)
```
to
```
,
```
value
```
,
```
data
```
,
```
gasLimit
```
: from the quote's
```
transactionRequest
```

If approval is NOT needed (native ETH swap, value > 0x0): Use
```
defi_send_transaction
```
with the quote's
```
transactionRequest
```
fields: to, value, data, chainId, and gasLimit (ALWAYS pass
```
gasLimit
```
from the quote).

NEVER construct approve calldata hex yourself. The

defi_approve

and

defi_approve_and_send

tools handle ABI encoding correctly.

Sui: For quotes where

fromChain

toChain

is Sui, use

defi_send_sui_transaction

with the quote's transaction bytes. No approval step.
