get_sample

Unsure what data you get? Access a free sample digest to learn the response contract. No wallet or API key needed.

Instructions

Frozen sample digest (2026-02-13) for learning the response contract before paying (GET /v1/sample). FREE, no wallet or API key required.

TDQS

A4.4/5.0
Behavior4/5

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

With no annotations, the description carries the burden. It discloses that it's free, requires no API key or wallet, and is a fixed sample (frozen date). It doesn't explicitly state it's read-only, but the context strongly implies a safe, non-mutating operation.

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

Conciseness5/5

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

The description is extremely concise: two short sentences with no redundant information. Every element (sample, date, purpose, endpoint, cost, auth) serves a purpose.

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?

Given the tool's simplicity (zero parameters, no output schema), the description provides sufficient context: what it is, why to use it, and cost/auth implications. It doesn't detail the response structure, but the stated purpose is to learn that contract via the sample itself.

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?

There are zero parameters, so the baseline is 4. The description adds context about the frozen date and sample nature, improving understanding beyond the empty schema.

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 what the tool does: it provides a frozen sample digest for learning the response contract. It distinguishes itself from siblings like get_digests by being a free sample, and includes a specific endpoint (GET /v1/sample).

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 phrase 'before paying' implies this is for trial/exploration and that other tools may require payment, providing clear context. It doesn't explicitly name alternative tools, but the usage intent is evident.

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