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

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

Error Handling

Error	Cause	Solution
`NO_PATH_FOUND`	No route available	Try different pair
`INSUFFICIENT_LIQUIDITY`	Low liquidity	Reduce amount
`SLIPPAGE_EXCEEDED`	Price moved	Increase slippage
