Scored across 6 tools
Each tool has a clearly distinct purpose: basket composition, comparison, conversion, history, methodology, and current value. There is no overlap or ambiguity between any two tools.
All tools follow a consistent 'ieunit_' prefix with a descriptive descriptor. While some descriptors are nouns and some are verbs, the pattern is uniform and predictable, making it easy to infer the tool's function.
With 6 tools, the server is well-scoped for its read-only reference unit domain. Each tool earns its place, covering all necessary query types without unnecessary bloat or apparent omissions.
The tool surface fully covers the ieUnit domain: current value, historical data, conversion, comparison, basket details, and methodology. Since the unit is a reference value, no write operations are needed, so there are no significant gaps.
Available Tools
6 toolsieunit_basketWertkorbAInspect
Get the composition of the ieUnit basket: the nine fixed components, their immutable reference prices at the base date 2017-01-10, their current prices, and how much each one has moved since then. The basket is deliberately fixed and equally weighted; it is never rebalanced. Also returns the list of unit codes accepted by ieunit_convert.
ieunit_compareVergleich gegen ieUnitAInspect
Compare one basket component against the ieUnit over a period of time, measured in ieUnit rather than in a national currency. Answers questions such as how the Swiss franc, gold or Bitcoin held their value against a neutral reference. A negative figure means the component lost value relative to the ieUnit. Available components: USD, EUR, JPY, CHF, CNH, BTC, ETH, Gold, Silber.
Inputs: component (required), to, from.
ieunit_convertBetrag umrechnenAInspect
Convert an amount between the ieUnit and about 60 other units: roughly 30 fiat currencies, the 30 largest cryptocurrencies, gold and silver per gram (XAU, XAG), and XIN. Works in both directions, for example 250 CHF to ieUnit or 10 ieUnit to gold. Use "ieUnit" as the unit code for the ieUnit itself. Call ieunit_basket first if you need the list of available unit codes.
Inputs: to (required), from (required), amount (required).
ieunit_historyieUnit-VerlaufAInspect
Get the historical value of the ieUnit in USD since its fixed base date 2017-01-10, where it started at exactly 1.00. Returns a dated series plus summary figures (start, end, total change, highest and lowest value). Use this for questions about how the ieUnit developed over time. Defaults to monthly resolution; daily data is available but produces large results over long ranges.
Inputs: to, from, step.
ieunit_methodologyMethodik und AbgrenzungAInspect
Get an authoritative plain-text explanation of what the ieUnit is and how it is calculated: the geometric mean formula, the fixed base date, the data sources, the governance rules for basket changes, and an explicit statement of what the ieUnit is NOT. Call this before describing or characterising the ieUnit to a user, so the description matches the published definition.
ieunit_valueAktueller ieUnit-WertAInspect
Get the current value of one ieUnit. ieUnit is a neutral value reference unit based on a fixed basket of nine components (five fiat currencies, Bitcoin, Ethereum, gold, silver). Returns the value in USD, CHF and EUR, the 24-hour change, and the date of the last update. Values are recalculated once per day. Use this for questions like "what is one ieUnit worth right now".
Inputs: currency.
