Analyzing wallet connections

address_counterparties

Read-only

Get 25 (per page) addresses or entities with the most common interactions with input addresses Default sort is net value transferred between them. Also returns the top 3 tokens transferred by count for each counterparty

Note: To get related wallets:

Focus on direct value transfers to get most likely addresses.
Include CEX deposit addresses (not withdrawal addresses!) as well.
Also go one level deeper:
- Find addresses that interacted with the most likely addresses.
- Find addresses that deposited to the same CEX deposit (NOT withdrawal!) addresses.
Address structure / string is not important, but the relationship is!

Sorting Options (all fields support "ASC"/"DESC"): Available for sorting: total_volume_usd, volume_in_usd, volume_out_usd, interaction_count

Examples:

Query by single address

{ "address": "0x123...", "sourceInput": "Combined", "groupBy": "wallet", "chain": "ethereum", "timeRange": {"from": "30D_AGO", "to": "NOW"}, "order_by": "total_volume_usd", "order_by_direction": "desc" }

Query by entity

{ "entity_id": "Binance", "sourceInput": "Combined", "groupBy": "entity", "chain": "all", "timeRange": {"from": "7D_AGO", "to": "NOW"} }

A4.4/5.0

Behavior4/5

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

The description adds behavioral details beyond the annotations (readOnlyHint=true, destructiveHint=false). It discloses the default page size (25), default sort (net value transferred), the return of top 3 tokens per counterparty, and the timeRange clamping behavior (max 365 days, clamped to recent year with effective range reported in response). These specifics are not present in the annotations and provide useful transparency about the tool's 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?

The description is lengthy but well-structured with clear sections: core purpose, a 'Note' for related-wallet strategies, sorting options, and two examples. The most critical information (what it does) is front-loaded. While some parts (e.g., the related-wallet note) could be considered extra, they are directly useful for agents seeking to maximize tool effectiveness. The structure makes it easy to scan, and no content is redundant or wasted.

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

Completeness5/5

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

The description covers all essential aspects for correct invocation: page size, default sort, sortable fields, timeRange tokens and clamping behavior, the distinction between address and entity queries, and the return of top tokens. It also includes examples that demonstrate valid parameter combinations. Given that an output schema exists (which documents return structure) and annotations cover safety, nothing critical is missing for an agent to use this tool effectively.

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?

The schema already has 100% description coverage, but the tool description adds valuable context: it explains the sorting fields and their semantics, provides relative time token examples (7D_AGO, 30D_AGO, etc.), clarifies the mutual exclusivity of address and entity_id, and includes two complete JSON examples demonstrating realistic parameter usage. This goes beyond the schema's individual parameter descriptions, enriching the agent's understanding of how to construct effective requests.

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

Purpose5/5

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

The description clearly states the tool's function: 'Get 25 (per page) addresses or entities with the most common interactions with input addresses'. It specifies the resource (addresses/entities), the action (get), the scope (most common interactions), and adds details about default sorting and token returns. This clearly distinguishes it from sibling tools like address_related_addresses, which focuses on related addresses rather than counterparty interaction ranking.

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?

The description includes a dedicated 'Note: To get related wallets' section that provides practical guidance on how to use this tool for finding related wallets (focusing on direct transfers, including CEX deposit addresses, and going one level deeper). It does not explicitly mention alternative tools or when not to use this tool, but the contextual guidance is clear and actionable. The examples also illustrate two distinct query patterns (address vs entity), which clarifies usage scenarios.

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