Loading token info

token_info

Read-only

Get token information — spot on-chain details or Hyperliquid perpetual futures stats.

On-chain tokens mode (default): Returns token details (name, symbol, market cap, FDV, supply, deployment date, socials) and spot trading metrics (volume, buys/sells, buyers/sellers, holders, liquidity).

Perps mode: Returns Hyperliquid perp stats — mark price, funding, open interest, buy/sell pressure, trader participation.

Returns: Token information as markdown.

On-chain tokens fields:
- **Market Cap / FDV**: Market capitalization and fully diluted valuation
- **Circulating / Total Supply**: Token supply metrics
- **Deployed**: When the token was deployed
- **Volume (Total / Buy / Sell)**: Trading volume in USD
- **Buys / Sells**: Number of buy/sell transactions
- **Unique Buyers / Sellers**: Distinct trading addresses
- **Total Holders**: Number of token holders
- **Liquidity**: Available liquidity in USD

Perps fields:
- **Mark Price**: Current perp mark price
- **Price Change**: Change vs previous price
- **Max Leverage**: Maximum leverage offered for the perp on Hyperliquid (e.g. "40x")
- **Funding Rate (hourly/annualized)**: Current funding rate
- **Open Interest**: Total current open interest in USD
- **Volume (Total / Buy / Sell)**: Perp volume in USD
- **Net Flow (Buy - Sell)**: Buy/sell pressure in USD
- **Traders**: Number of traders

Example: On-chain tokens (default mode): { "mode": "onchain_tokens", "chain": "ethereum", "tokenAddress": "0xa0b86a33e6b6c4b3add000b44b3a1234567890ab", "timeframe": "1d" }

Hyperliquid perps:
```
{
  "mode": "perps",
  "tokenAddress": "BTC",
  "timeframe": "7d"
}
```

Notes: - On-chain tokens mode uses contract addresses - Perps mode uses token symbols (e.g. BTC, ETH, HYPE) - Both modes use the same timeframe parameter

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, so the safety profile is covered. The description adds real behavioral detail beyond that: the mode-defaulting rule for symbol vs. contract-address input, the fact that both modes reuse the same timeframe parameter, and the markdown return format. The long field catalogs are largely duplicated by the existing output schema, so it stops short of a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The opening two-mode summary is well front-loaded and the examples are useful, but the two exhaustive field bullet lists also duplicate the output schema and could be dropped without loss. Roughly half the text is redundant reference material rather than decision-relevant guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with nested parameters, an output schema, and full annotation coverage, the description supplies what an agent needs to call it correctly: mode choice, input type per mode, timeframe reuse, and example payloads. The one wrinkle is labeling on-chain as the '(default)' mode while the schema explains that a symbol input actually defaults to perps; the schema resolves it but the description phrasing is slightly at odds.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, including a mode description that already explains the symbol-to-perps default, so the baseline is 3. The description restates that mapping ('On-chain tokens mode uses contract addresses / Perps mode uses token symbols') and shows example values, which is helpful but adds little the schema does not already state.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource ('Get token information') and immediately splits it into two named modes, on-chain spot details vs. Hyperliquid perps stats. That is far clearer than the title alone, but it never distinguishes this tool from close siblings such as token_ohlcv, token_current_top_holders, or token_flows, which an agent would have to disambiguate on its own.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives concrete context for each mode: on-chain mode takes contract addresses and `chain`, perps mode takes symbols like BTC/ETH/HYPE, and both share `timeframe`. Worked JSON examples reinforce which mode to pick. What is missing is any exclusion or comparison against sibling token tools, so the agent gets clear context but no explicit when-not guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
