getCoinMarkets

Read-onlyIdempotent

Get the specific markets and trading pairs where a coin trades, with per-market price and 24h volume. Use for 'where can I buy X', 'X price on Binance', 'best market for X'. For just the list of exchange names use getCoinExchanges. Read-only; coinId is a canonical id, quotes sets quote currencies, limit caps results. No API key required.

Input Schema

Name	Required	Description
`limit`	No
`coinId`	Yes	Canonical CoinPaprika coin slug in 'symbol-name' format, e.g. 'btc-bitcoin', 'eth-ethereum', 'ada-cardano'. Do NOT pass ticker symbols ('BTC', 'AAVE') or guess the slug; it is not derivable from the symbol (e.g. AAVE resolves to 'aave-new', which you could not guess). Call search or resolveId first to resolve a symbol or name to its canonical id.
`quotes`	No
`rationale`	Yes	REQUIRED. In 1-2 sentences explain WHY you are calling this tool and what you intend to do with the result. Examples: 'User asked for BTC price; calling getTickersById to fetch current USD value.' 'Building a portfolio dashboard; need OHLCV for ETH last 7 days.' This is logged and reviewed to improve the MCP. Do not include user PII or secrets; use generic descriptions.

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered; the description's 'Read-only' merely repeats it. It does add useful operational context — no API key required — and clarifies that coinId must be canonical rather than a ticker, but says nothing about rate limits or result ordering.

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?

Three compact sentences: purpose and payload first, then routing examples, then the alternative sibling and operational notes. No filler and nothing important buried.

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?

An output schema exists, so return values need no prose, and annotations cover safety. Combined with a richly documented coinId, the definition is nearly complete; the remaining gaps are the quotes value format and whether limit truncates or paginates.

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 description coverage is 50%: coinId and rationale are richly documented in the schema, while limit and quotes have no schema descriptions. The description gives role-level meaning for both ('quotes sets quote currencies', 'limit caps results') but not the format — an agent cannot tell whether quotes is a comma-separated string like 'USD,BTC' or a repeated list, which is an invocation risk.

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 — the markets/trading pairs where a coin trades — plus the payload it returns (per-market price and 24h volume). It explicitly differentiates from the nearest sibling, getCoinExchanges, which returns only exchange names.

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?

Provides concrete user phrasings ('where can I buy X', 'X price on Binance', 'best market for X') that trigger this tool and names the alternative (getCoinExchanges) with the condition that selects it. The schema further routes to resolveId/search before calling.

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