Convert currency on a real, dated rate
Ask for a conversion and Zeplik reads a live reference exchange rate from the European Central Bank, then answers with the real figure and the exact date it was published. Not a rate half-remembered from training data, which is always months or years stale and quietly wrong for any invoice, cost basis, or price. Give it a base and target currency for the latest rate, or a date for a historical one; when it cannot verify a pair it says so plainly instead of inventing a number.
The lookup is free; you pay only the normal cost of the answer, shown before you send.
How it works
Name the currencies and amount
Ask in plain language, like 'what is 500 USD in euros right now?' or 'convert 1200 GBP to JPY'. Naming the currencies is enough for Zeplik to run the lookup; you do not have to open a tool explicitly. Add a date (for example 'on 2024-01-15') for a historical rate.
Zeplik reads the live ECB rate
It fetches the current or historical reference rate from the European Central Bank via Frankfurter, not the model's training memory, and treats the result as source data. A weekend or holiday request resolves to the prior working day, and the answer cites that exact date so the figure is never mislabeled.
Read the dated conversion and act
The answer states the rate, the converted amount, and the date the rate belongs to, so you can put it straight into an invoice, expense report, or cost-basis calculation and know exactly which day it reflects.
Worked examples
Real prompts you can open in the composer with the text ready to review. Nothing sends on its own. Swap in your own details.
Prompt: What is 2,500 USD worth in euros and Japanese yen right now?
Zeplik reads the latest ECB reference rates for EUR and JPY, converts the amount, and states the exact publication date so the figures are auditable, not a confident guess from stale memory.
Open this in ZeplikPrompt: Convert 10,000 GBP to USD using the exchange rate on 2024-01-15
Give a date and it fetches the real historical reference rate for that day (or the prior working day, which it names), so a cost-basis or contract figure is grounded in what the rate actually was.
Open this in ZeplikPrompt: I invoiced a client 4,200 CHF. How much is that in CAD and AUD?
It handles cross-rates from any base to multiple targets in one answer, each on the same dated reference rate, so a multi-currency reconciliation lines up.
Open this in ZeplikWhat it can and cannot do
The lookup is precise about what it can verify and honest about its edges. Here is the plain posture.
Give a base and one or more target currencies and Zeplik returns the latest ECB reference rate for each, with the exact date it was published.
Ask for a specific day and it fetches the real reference rate for that date, resolving weekends and holidays to the prior working day and naming which day it used.
Convert one base into several targets in a single answer, each on the same dated rate, which is handy for multi-currency invoices and reconciliations.
If a pair is unsupported or the source is unreachable, Zeplik tells you plainly rather than quoting a rate from memory that would silently corrupt the conversion.
These are ECB daily reference rates for accounting and reporting, not the live dealing price your bank or broker quotes with its own spread and fees.
The European Central Bank does not publish crypto reference rates, so a coin-to-fiat conversion is outside what this grounded source can verify.
Grounded, and honest by default
- It cites the exact rate date. Every conversion states the day the rate was published, so a weekend request is never silently labeled as today and a historical figure is never confused with the current one.
- It will not recall a rate from memory. When a pair cannot be verified, Zeplik says the lookup returned nothing rather than filling in a plausible-looking number that would be stale by months or years.
- Rate data cannot hijack the answer. The reference-rate response is treated as untrusted content: Zeplik reads and reports it but never obeys instructions embedded inside it.
Frequently asked questions
- Where do the exchange rates come from?
- From the European Central Bank's published daily reference rates, read live via the keyless Frankfurter service. These are the same rates widely used for accounting and reporting, so any figure Zeplik returns is a real published number with its date, not an estimate.
- Why not just ask a chatbot for the exchange rate?
- Because a language model on its own answers from its training snapshot, and exchange rates move every day, so a remembered rate is stale the moment it is quoted and can be wrong by a wide margin. This tool reads the live reference rate and cites the exact date, so you can trust the conversion.
- Can it give me a historical rate for a specific date?
- Yes. Include a date in your question and Zeplik fetches the real reference rate for that day. If the date falls on a weekend or holiday, it uses the prior working day's rate and tells you which day that was, so the figure is never mislabeled.
- Is this the rate my bank will give me?
- Not exactly. These are central-bank reference rates, ideal for invoices, expense reports, and cost-basis figures. Your bank or broker applies its own spread and fees, so a live dealing price will differ slightly. Zeplik is clear about this distinction.
- Does the conversion cost credits?
- The rate lookup itself is free. You pay only the normal model-token cost of the answer Zeplik writes around it, shown before you send, exactly like any other message.
