## Get Swap Quote

```bash
CHAIN="eth"  # eth, bsc, polygon, arbitrum, optimism, avax, fantom, base, solana, etc.

# Token addresses
IN_TOKEN="0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE"   # ETH
OUT_TOKEN="0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"  # USDC
AMOUNT="1000000000000000000"  # 1 ETH in wei
ACCOUNT="<YOUR_WALLET>"

# Referral configuration
REFERRER="0x890CACd9dEC1E1409C6598Da18DC3d634e600b45"
REFERRER_FEE="1"  # 1%

curl -s "https://open-api.openocean.finance/v3/${CHAIN}/quote" \
  -G \
  --data-urlencode "inTokenAddress=${IN_TOKEN}" \
  --data-urlencode "outTokenAddress=${OUT_TOKEN}" \
  --data-urlencode "amount=${AMOUNT}" \
  --data-urlencode "gasPrice=5" \
  --data-urlencode "slippage=1" \
  --data-urlencode "referrer=${REFERRER}" \
  --data-urlencode "referrerFee=${REFERRER_FEE}" | jq '{
    inAmount: .data.inAmount,
    outAmount: .data.outAmount,
    estimatedGas: .data.estimatedGas,
    path: .data.path
  }'
```

## Get Swap Transaction

```bash
curl -s "https://open-api.openocean.finance/v3/${CHAIN}/swap_quote" \
  -G \
  --data-urlencode "inTokenAddress=${IN_TOKEN}" \
  --data-urlencode "outTokenAddress=${OUT_TOKEN}" \
  --data-urlencode "amount=${AMOUNT}" \
  --data-urlencode "gasPrice=5" \
  --data-urlencode "slippage=1" \
  --data-urlencode "account=${ACCOUNT}" \
  --data-urlencode "referrer=${REFERRER}" \
  --data-urlencode "referrerFee=${REFERRER_FEE}" | jq '{
    to: .data.to,
    data: .data.data,
    value: .data.value,
    outAmount: .data.outAmount
  }'
```

## Cross-Chain Swap

```bash
FROM_CHAIN="eth"
TO_CHAIN="bsc"
IN_TOKEN="0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"   # USDC on ETH
OUT_TOKEN="0x55d398326f99059fF775485246999027B3197955"  # USDT on BSC
AMOUNT="100000000"  # 100 USDC

curl -s "https://open-api.openocean.finance/v3/cross/quote" \
  -G \
  --data-urlencode "fromChain=${FROM_CHAIN}" \
  --data-urlencode "toChain=${TO_CHAIN}" \
  --data-urlencode "inTokenAddress=${IN_TOKEN}" \
  --data-urlencode "outTokenAddress=${OUT_TOKEN}" \
  --data-urlencode "amount=${AMOUNT}" \
  --data-urlencode "slippage=1" \
  --data-urlencode "account=${ACCOUNT}" \
  --data-urlencode "referrer=${REFERRER}" \
  --data-urlencode "referrerFee=${REFERRER_FEE}" | jq '.'
```

## Get Token List

```bash
curl -s "https://open-api.openocean.finance/v3/${CHAIN}/tokenList" | jq '.data[:10] | .[] | {symbol: .symbol, address: .address, decimals: .decimals}'
```

## Get Gas Price

```bash
curl -s "https://open-api.openocean.finance/v3/${CHAIN}/gasPrice" | jq '.data'
```

## Check Balance

```bash
curl -s "https://open-api.openocean.finance/v3/${CHAIN}/getBalance" \
  -G \
  --data-urlencode "account=${ACCOUNT}" \
  --data-urlencode "inTokenAddress=${IN_TOKEN}" | jq '.data'
```

## Safety Rules

1. **ALWAYS** display swap details before execution
2. **WARN** if price impact > 1%
3. **CHECK** token allowance before swap
4. **VERIFY** cross-chain destination address
5. **NEVER** execute without user confirmation

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `INSUFFICIENT_BALANCE` | Low balance | Check wallet balance |
| `NO_ROUTE` | No route found | Try different pair |
| `SLIPPAGE_TOO_HIGH` | Price moved | Increase slippage |
