Finding recent traders

token_who_bought_sold

Read-only

Get net buyers or net sellers of a token on DEX (Decentralised Exchanges) only.

Use this tool to find out WHO is buying or selling a token (on DEX) AND then you can check if they are liquidating profits or accumulating more.

Returns: Aggregated buyer/seller activity as markdown. Returns empty string if no trading data found.

Columns returned:
- **Address**: Trader's wallet address
- **Label**: Nansen label of the address
- **Bought Token Volume**: Total quantity of tokens purchased
- **Sold Token Volume**: Total quantity of tokens sold
- **Total Token Volume**: Bought plus sold
- **Net Bought / Net Sold Token Volume**: Bought minus sold for BUY results, or sold minus bought for SELL results
- **Bought Volume USD**: USD value of all token purchases
- **Sold Volume USD**: USD value of all token sales
- **Total Volume USD**: Bought plus sold
- **Net Bought / Net Sold Volume USD**: Bought minus sold for BUY results, or sold minus bought for SELL results

Sorting Options: Sort ASC or DESC by net_token_volume (default: biggest net buyers or sellers first), token_trade_volume (total volume: most active traders, such as market-making bots), bought_token_volume, or sold_token_volume.

Notes: - buy_or_sell parameter filters for "BUY" (net buyers) or "SELL" (net sellers), decided by net token amount - Net USD volume can be negative while net token volume is zero or positive, because USD is priced per trade - min_trade_volume_usd applies to the requested side: bought USD for BUY, sold USD for SELL - Machine-readable rows: token_trade_volume / trade_volume_usd are total volume (bought + sold); net_token_volume / net_volume_usd are net volume. - Aggregates all trading activity within the specified time range

Behavior4/5

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

Annotations already cover the read-only, non-destructive, open-world profile, so the description is free to add operational detail, and it does: aggregation across the requested time range, empty-string return on no data, and the caveat that net USD can go negative while net token volume is zero or positive. It stops short of stating auth/entitlement requirements or pagination behavior.

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

Conciseness4/5

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

Purpose and the WHO framing are front-loaded, and the notes/sorting blocks are scannable. The 11-row column listing is the weakest part, since an output schema exists and much of that block restates field names, though the net-volume interpretation adds genuine value.

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 nested, single-request analytics tool, the description covers what is returned, how sorting and side filtering work, and two non-obvious edge cases (negative net USD, side-specific volume threshold). The only material omission is pagination semantics for the 'page' field.

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

Parameters4/5

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

Schema coverage is 100% so baseline is 3, but the description adds real meaning: buy_or_sell is decided by net token amount, min_trade_volume_usd applies to the requested side (bought USD for BUY, sold USD for SELL), and the sort options are explained in terms of trader behavior. It does not explain the 'page' parameter, leaving one gap.

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?

States a specific verb and resource: 'Get net buyers or net sellers of a token on DEX only,' which tells an agent exactly what dataset comes back. The DEX-only scoping further narrows it against the broader trade/transfer siblings. It does not name a specific sibling (e.g., token_dex_trades or token_current_top_holders) to distinguish itself explicitly, keeping it at 4.

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

Usage Guidelines3/5

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

'Use this tool to find out WHO is buying or selling a token (on DEX) AND then you can check if they are liquidating profits or accumulating more' gives an actionable intent, and 'on DEX only' sets a boundary. However, there is no explicit statement of when NOT to use it or which sibling to pick for raw trade-level, holder, or CEX data; an agent must infer the routing.

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