XXYY Trade

On-chain token trading and data queries on Solana, Ethereum, BSC, and Base via XXYY Open API.

Prerequisites

Set environment variables before use:

• XXYY_API_KEY (required) -- Your XXYY Open API Key (format: xxyy_ak_xxxx). Get one at https://www.xxyy.io/apikey
• XXYY_API_BASE_URL (optional) -- API base URL, defaults to https://www.xxyy.io

Authentication

All requests require header: Authorization: Bearer $XXYY_API_KEY

Security Notes

• ⚠️ API Key = Wallet access -- Your XXYY API Key can execute real on-chain trades using your wallet balance. If it leaks, anyone can buy/sell tokens with your funds. Never share it, never commit it to version control, never expose it in logs or public channels. If you suspect a leak, regenerate the key immediately at https://xxyy.io.
• Custodial trading model -- XXYY is a custodial trading platform. You only provide your wallet address (public key) and API Key. No private keys or wallet signing are needed -- XXYY executes trades on your behalf through their platform.
• No read-only mode -- The same API Key is used for both data queries (Feed, Token Query) and trading (Buy, Sell). There is currently no separate read-only key.

API Reference

Buy Token

POST ${XXYY_API_BASE_URL:-https://www.xxyy.io}/api/trade/open/api/swap

{
  "chain": "sol",
  "walletAddress": "<user_wallet>",
  "tokenAddress": "<token_contract>",
  "isBuy": true,
  "amount": 0.1,
  "tip": 0.001,
  "slippage": 20
}

Buy Parameters

Sell Token

POST ${XXYY_API_BASE_URL:-https://www.xxyy.io}/api/trade/open/api/swap

{
  "chain": "sol",
  "walletAddress": "<user_wallet>",
  "tokenAddress": "<token_contract>",
  "isBuy": false,

Sell Parameters

tip / priorityFee Rules

• tip (required) -- Universal priority fee for ALL chains. EVM chains (eth/bsc/base) use tip as the priority fee. If tip is not provided, the API falls back to priorityFee.
  • SOL chain: unit is SOL (1 = 1 SOL, very expensive). Recommended range: 0.001 - 0.1
  • EVM chains (eth/bsc/base): unit is Gwei. Recommended range: 0.1 - 100
• priorityFee (optional) -- Only effective on Solana chain. Solana supports both tip and priorityFee simultaneously.

Execution Rules

1. Always confirm before trading -- Ask user to confirm: chain, token address, amount/percentage, buy or sell
2. Auto-query wallet -- If the user does not provide a wallet address: a. If there is a remembered default wallet for that chain, use it directly and show its current balance via Wallet Info API before confirming. b. Otherwise, call List Wallets API. If only 1 wallet exists, auto-select it. If multiple, ask user to choose. If none, guide to create at https://www.xxyy.io/wallet/manager?chainId={chain}. c. Remember the selected wallet as default for that chain. d. If the user provides a wallet address, call Wallet Info API to verify it exists and show its balance before confirming the trade.
3. Use Bash with curl to call the API
4. Poll trade result -- After swap submission, query trade status up to 3 times with 5s intervals
5. Show transaction link -- Always display the block explorer URL with the txId
6. Never retry failed swap requests -- show the error to user instead
7. Chain-wallet validation -- walletAddress must match the selected chain. A Solana wallet cannot be used for BSC/ETH/Base trades and vice versa. If the user provides a mismatched wallet/chain combination, warn them and ask to correct before proceeding.
8. Strict parameter validation -- Before calling the API, validate EVERY field:
   • All required parameters must be present and have legal values
   • chain must be one of sol/eth/bsc/base
   • isBuy must be boolean true or false
   • amount for buy: must be > 0; for sell: must be 1-100
   • tip must be provided; SOL chain: 0.001-0.1 (unit: SOL); EVM chains: 0.1-100 (unit: Gwei). If tip is outside the recommended range, must warn the user about potentially high cost and require explicit confirmation before proceeding
   • model if provided must be 1 or 2
   • priorityFee if provided only applies to Solana chain
   • Do NOT send any field names outside the parameter tables above
   • If any validation fails, refuse to send the request and ask the user to correct

Feed Rules

1. type validation -- Only accept NEW, ALMOST, COMPLETED (uppercase). Reject any other value.
2. chain validation -- Feed only supports sol and bsc. If user specifies eth or base, reject and inform them that Feed scanning is only available on Solana and BSC chains.
3. Single query mode (default) -- Call the Feed API once, format and display key info for each token: symbol, priceUSD, marketCapUSD, holders, devHoldPercent, launchPlatform (name + progress).
4. Continuous monitor mode -- Activate only when user explicitly says "持续监控", "monitor", or "watch":
   • Use a Bash polling loop, calling Feed API every 5 seconds
   • Deduplicate by tokenAddress — only display newly appeared tokens
   • Loop limit: 480 seconds (8 minutes). Set Bash timeout to 540000ms
   • After loop ends, use AskUserQuestion to ask: continue monitoring / view token details / buy a token / stop
   • When continuing, preserve the seen tokenAddress set to avoid repeats
5. Filter guidance -- Before querying, optionally ask user about filter preferences (market cap range, liquidity, holder count, etc.). If not asked, use no filters (return all).
6. No auto-trading -- Feed scanning is for observation only. NEVER automatically buy or sell based on scan results.
7. Error handling -- See Error Codes table. For data query APIs: code == 200 with success == true means success; code == 300 is server error (inform user to retry later); code == 8060/8061 means stop immediately; code == 8062 means wait 2 seconds and retry.

Token Query Rules

1. ca required -- Contract address (ca) must be provided. If missing, ask user for it.
2. chain validation -- Supports all 4 chains: sol, eth, bsc, base. Default sol.
3. HoneyPot warning -- If securityInfo.honeyPot == true, display a prominent warning that this token is a honeypot and trading it is extremely risky.
4. High tax alert -- If taxInfo.buy or taxInfo.sell > 5%, warn user about high tax rates.
5. Display format -- Present results in groups: Trade Info → Security Check → Tax Rates → Holder Distribution → Social Links.
6. Trade follow-up -- After displaying query results, optionally ask user if they want to buy this token, linking to the Buy Token flow.
7. Error handling -- Same as Feed Rules (see Error Codes table).

Wallets Rules

1. chain validation -- Supports all 4 chains. Default sol.
2. Display format -- Show wallet name, address, native balance. Mark pinned wallets with ⭐.
3. Token holdings -- If user asks about specific token holdings, pass tokenAddress to show per-wallet balance.
4. No wallets -- If response returns empty list, guide user to create at: https://www.xxyy.io/wallet/manager?chainId={chain}
5. Default wallet memory -- After user selects a wallet, remember it as the default for that chain in the current session. Use this default for subsequent trades on the same chain without asking again.
6. Single wallet query -- When the user provides a specific wallet address and asks for its balance, use Wallet Info API instead of List Wallets. Also use Wallet Info to show balance before trade confirmation.
7. Error handling -- Same as other data query APIs (see Error Codes table).
