FX Spot Rates

forex
Read-only

Get raw historical FX spot-rate rows for a currency pair (e.g. EUR/USD, USD/JPY). Prefer this tool when the user explicitly wants a plain-text table, raw rows, exact values, JSON-like data, or technical-indicator series (SMA, EMA, RSI, MACD, Bollinger Bands, etc.) computed from spot without a chart. If the user asks more generally to show/tell/explain the last few weeks or months of a pair, prefer forex_visual_artifact instead so the client can render a chart. Daily granularity from official central-bank reference rates with full multi-year history. Supported currencies (use lowercase 3-letter codes): AUD, BRL, CAD, CHF, CNH, CNY, DKK, EUR, GBP, HUF, ILS, JPY, KRW, MYR, NGN, NOK, NZD, PEN, SEK, THB, TWD, USD. Optional indicators parameter accepts a comma-separated list of technical indicator slugs to attach to each row. Supported indicator values: adx_14, atr_14, bollinger_bands, cci_20, donchian_20, ema_12, ema_20, ema_200, ema_26, ema_50, macd, macd_histogram, macd_signal, rsi_14, sma_20, sma_200, sma_50, stochastic_14_3, williams_r_14, all. Access: requires an FXMacroData API key; an anonymous call returns subscription_required with a subscribe link.

A4.4/5.0
Behavior4/5

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

Annotations already cover read-only and non-destructive nature. The description adds valuable behavioral context: daily granularity from central-bank reference rates, full multi-year history, and the authentication requirement (API key; anonymous returns subscription_required). It also hints at the output style (raw rows, plain-text table). This goes beyond annotations without contradicting them.

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 long but information-dense. It front-loads the core purpose and usage guidance, then covers data source, supported values, and access requirements in a logical order. Every sentence adds value; there is no fluff. While longer than the ideal two-sentence example, the complexity of the tool justifies the length.

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 tool's complexity (5 parameters, indicator list, currency list, authentication), the description is comprehensive. It covers purpose, usage, data source, authentication, and supported options. Since an output schema exists, return-value details are not needed. No critical information is missing for an agent to select and invoke the tool correctly.

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 100%, so the baseline is 3. The description restates the supported currencies and indicator slugs, which are already in the schema. It adds minor nuance like 'use lowercase 3-letter codes' and 'comma-separated list', but these are largely redundant. The description does not significantly enrich parameter understanding beyond the 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 the tool's purpose: 'Get raw historical FX spot-rate rows for a currency pair'. It also explicitly differentiates from the sibling forex_visual_artifact by specifying when to prefer each. The verb, resource, and scope are unambiguous.

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?

It provides explicit guidance: 'Prefer this tool when the user explicitly wants a plain-text table, raw rows, exact values...' and 'If the user asks more generally... prefer forex_visual_artifact instead.' This names the alternative and the exact conditions, leaving no ambiguity.

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