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"} }

A3.6/5.0

Behavior4/5

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

Annotations already cover safety (readOnlyHint=true, destructiveHint=false, openWorldHint=true), and the description adds non-obvious behavior: 25 results per page, default sort by net value transferred, and that top 3 tokens by count are returned per counterparty. It also notes that long ranges are clamped to one year with the effective range reported, which is useful operational context beyond the annotations.

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?

Purpose, default sort, and return shape are correctly front-loaded, and the two examples are useful. But the multi-level 'Note: To get related wallets' bullet list is lengthy investigative advice rather than tool definition, and the repeated 'ASC'/'DESC' notation plus the enum mismatch add noise for a single-object request body.

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?

With an output schema present, the description needn't detail response structure yet still flags the top-3-tokens payload; the schema handles address/entity mutual exclusion and time-range tokens, and the description adds the 30-day default and 365-day clamping. What remains missing is any pointing to the batch or related-addresses alternatives.

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 coverage is 100% so the schema already documents address/entity exclusivity, enums, and time-range tokens; the description's list of sortable fields merely echoes the enum. Worse, the examples use 'order_by' while the schema property is 'orderBy', a naming mismatch that could lead an agent to send an unknown key, which offsets the illustrative value of the examples.

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?

Opens with a specific verb and resource: 'Get 25 (per page) addresses or entities with the most common interactions with input addresses', and immediately states the default sort and the extra data returned. It doesn't name any sibling (e.g. address_related_addresses or address_counterparties_batch), so an agent must infer the boundary from the name alone.

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?

The 'Note: To get related wallets' block gives analytical usage guidance (focus on direct value transfers, include CEX deposit addresses, go one level deeper), which tells the agent what the output is good for. However, it never states when to use this tool instead of its clearly overlapping siblings like address_related_addresses or address_counterparties_batch, so tool selection is left to inference.

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