getExchanges

Read-onlyIdempotent

List exchanges tracked by CoinPaprika as a list ranked by rank, each with id, name, trust score, active market count and 24h volume. Use for 'top exchanges by volume', 'biggest crypto exchanges', or to find an exchangeId before calling getExchangeByID. For one exchange's full stats use getExchangeByID; for its trading pairs use getExchangeMarkets. Read-only. Params: quotes (optional, default 'usd') is a comma-separated list of quote currencies for the volume figures, for example 'usd,btc'; limit (optional, default 50, max 250) caps how many exchanges return. No API key required.

A4.6/5.0

Behavior4/5

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

Annotations already declare read-only, idempotent, non-destructive, open-world behavior. The description adds useful context beyond that: results are ranked by rank, volume figures depend on quote currencies, no API key is required, and the limit has a max of 250.

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 front-loaded with purpose, then usage routing, then parameters. It is somewhat long, but nearly every sentence adds actionable information; 'Read-only' lightly repeats the annotation and is the only minor redundancy.

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?

Given the rich annotations and output schema, the description supplies everything else an agent needs: scope, ranking, output fields, alternatives, auth requirement, and parameter behavior. No important invocation detail is missing.

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 only 33%, so the description must carry parameter meaning. It explains quotes as a comma-separated list with default 'usd' and an example, and limit as a cap with default 50 and max 250. The required rationale parameter is not described here, but the schema documents it thoroughly.

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?

States a specific verb and resource ('List exchanges tracked by CoinPaprika'), describes the ordering and returned fields, and explicitly distinguishes itself from getExchangeByID and getExchangeMarkets. An agent can identify this tool without opening the schema.

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

Usage Guidelines5/5

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

Gives concrete use cases ('top exchanges by volume', 'biggest crypto exchanges') and explicitly names alternatives for other tasks: getExchangeByID for single-exchange stats, getExchangeMarkets for trading pairs. It also explains the common workflow of finding an exchangeId first.

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