getCoinOHLCVLatest

Read-onlyIdempotent

Get the latest full-day OHLC candle (open, high, low, close and volume) for a coin. Use for 'yesterday's candle for BTC'. For the live spot price use getTickersById. Read-only; coinId must be a canonical id (resolve a bare symbol with resolveId first), quote defaults to usd. No API key required.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`quote`	No		usd
`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.
`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.

A4.3/5.0

Behavior4/5

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

Annotations already mark the tool read-only, idempotent, and non-destructive. The description adds useful behavioral context beyond annotations: no API key is required, quote defaults to usd, and coinId must be a canonical id resolved via resolveId. This helps an agent invoke it safely and correctly.

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 three concise sentences with no filler. It front-loads the core function, then provides a concrete use case and a pointer to the relevant alternative.

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 output schema, annotations, and sibling context, the description covers the key invocation details: canonical id resolution, default quote, no authentication required, and the distinction from live spot price. Potential confusion with OHLCVToday/Historical is mitigated by the 'full-day' and 'yesterday's candle' phrasing.

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?

The description mostly restates the schema's existing default for quote and the canonical coinId rule already detailed in the coinId property description. It adds little new parameter meaning beyond what the schema already provides, though it does helpfully surface the quote default and the resolveId requirement in prose.

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 states a specific verb and resource: 'Get the latest full-day OHLC candle...for a coin.' It names the exact fields (open, high, low, close and volume) and explicitly contrasts with getTickersById for live spot price, making the tool's scope clear relative to siblings.

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?

It gives an explicit use case ('yesterday's candle for BTC') and an explicit alternative for a different need ('For the live spot price use getTickersById'). It does not explicitly mention getCoinOHLCVToday or getCoinOHLCVHistorical, though 'latest full-day' and 'yesterday's candle' imply the distinction.

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