Multi-Output Swap (Split to Multiple Tokens)

# Swap ETH to 50% USDC + 50% DAI
curl -s -X POST "https://api.odos.xyz/sor/quote/v2" \
  -H "Content-Type: application/json" \
  -d "{
    \"chainId\": ${CHAIN_ID},
    \"inputTokens\": [{

      \"amount\": \"${INPUT_AMOUNT}\"
    }],
    \"outputTokens\": [
      {
        \"tokenAddress\": \"0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48\",
        \"proportion\": 0.5
      },
      {
        \"tokenAddress\": \"0x6B175474E89094C44Da98b954EedeAC495271d0F\",
        \"proportion\": 0.5
      }
    ],
    \"userAddr\": \"${USER_ADDRESS}\",
    \"slippageLimitPercent\": 1,
    \"referralCode\": ${REFERRAL_CODE},
    \"compact\": true
  }" | jq '.'

Supported Chains

Get Token List

curl -s "https://api.odos.xyz/info/tokens/${CHAIN_ID}" | jq '.tokenMap | to_entries[:10] | .[] | {symbol: .value.symbol, address: .key, decimals: .value.decimals}'

Get Liquidity Sources

curl -s "https://api.odos.xyz/info/liquidity-sources/${CHAIN_ID}" | jq '.[] | {id: .id, name: .name}'

Check Contract Info

curl -s "https://api.odos.xyz/info/contract-info/v2/${CHAIN_ID}" | jq '{
  routerAddress: .routerAddress,
  executorAddress: .executorAddress
}'

Safety Rules

1. ALWAYS display swap details before execution
2. WARN if price impact > 1%
3. CHECK token allowance before swap
4. VERIFY output amounts
5. NEVER execute without user confirmation
