# DexScreener Token Information

#### DexScreener Token Information Tool (`dexscreener_token_information_tool`)

Fetches detailed Decentralized Exchange (DEX) market data for one or more specified token addresses from DexScreener. Provides insights into price, volume, liquidity, and trading activity on a given blockchain (defaults to Solana).

{% hint style="info" %}
**Input:** Requires a comma-separated list of `token_addresses` and an optional `chain_id`.
{% endhint %}

```python
class DexScreenerTokenInformationInput(BaseModel):
    token_addresses: str  # e.g., "So1111...1112,EPjF...TDt1v" (max 10)
    chain_id: str = "solana" # Blockchain ID (e.g., "ethereum", "bsc")
```

***

**Key Functionality:**

* Retrieves detailed DEX information for up to 10 token addresses from `api.dexscreener.com`.
* For each token/pair found, it includes: price (USD & native), 24h price change, 24h volume, liquidity, transaction counts, market cap (if available), and a link to the pair on DexScreener.
* Supports various blockchains via the `chain_id` parameter.

***

**Sample Usage Queries (How an AI might use it):** *(Note: For queries using names/tickers, the system would first use a token identification tool to get addresses.)*

* "Get DexScreener info for token `DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263` on Solana."
* "Show me the DexScreener data for Wrapped SOL and USDC on the solana chain."
* "Fetch DEX details for Raydium and Serum from DexScreener."
* "What's the trading activity for Jito (`jtojt...mCL`) according to DexScreener?"
* "Look up details for mint `token_mint_address_placeholder` on Ethereum using DexScreener."
* "Get DexScreener info for LUMO, FARTCOIN, and GOAT." (Defaults to Solana if chain not specified)
* "DexScreener details for `contract_addr1,contract_addr2` on bsc chain?"

***

**Quick Code Glance:**

```python
class DexScreenerTokenInformationTool(BaseTool):
    name: ClassVar[str] = "dexscreener_token_information_tool"
    description: ClassVar[str] = "Get detailed DEX information about Solana tokens including price, volume, liquidity, and trading activity."
    args_schema: ClassVar[Type[BaseModel]] = DexScreenerTokenInformationInput
```

***

**Important:**

* This tool operates primarily **asynchronously** (`_arun`). The synchronous version returns an informational message.
* Relies on the external DexScreener API (`api.dexscreener.com`); functionality and data accuracy depend on this service.
* Can query a maximum of 10 token addresses per call.
* Ensure the `chain_id` is correct if querying tokens outside of Solana.
