Open the folder **01 — Metadata**. Those three requests need no API key, so you can\n   send one right now.\n2. [Create a free account](https://currencyfreaks.com/signup) and copy your key from the\n   dashboard.\n3. Set the `apikey` collection variable to your key — paste it into the **Current value**\n   column.\n4. Send **02 — Latest Rates → Latest Rates — filtered by symbols**.\n\nAuthentication is configured once at collection level, as an API key in the query string\nnamed `apikey`, and every request inherits it. There is no header-based alternative.\n\n## Variables\n\n| Variable | Default | Purpose |\n| --- | --- | --- |\n| `baseUrl` | `https://api.currencyfreaks.com/v2.0` | API root |\n| `apikey` | `YOUR_APIKEY` | Your API key. Paste into **Current value** so it stays local to you. |\n\n## What's included\n\n| Folder | Contents |\n| --- | --- |\n| 01 — Metadata | Currency catalogue, display names, historical coverage. No key needed. |\n| 02 — Latest Rates | Current rates, symbol filtering, custom base, XML |\n| 03 — Conversion | Convert an amount at current or past rates |\n| 04 — Historical Rates | Single date, daily time series, period fluctuation |\n| 05 — IP to Currency | Localise prices from a visitor's IP address |\n| 06 — Error Handling | Deliberate failures showing the error envelope |\n\nEvery request carries tests, so you can run the whole collection in the Collection Runner\nor via Newman and confirm your integration end to end.\n\n## Plans\n\nEndpoint availability depends on your subscription. A request outside your plan returns\n`402` with `This feature is available on {PLAN_NAME} plan and onwards!`\n\n| Tier | Unlocks |\n| --- | --- |\n| No key | `/supported-currencies`, `/currency-symbols`, `/historical-data-limits` |\n| Free | `/rates/latest` |\n| Any paid plan | `base` parameter, `/convert/latest`, `/rates/historical`, `/convert/historical` |\n| Growth and above | `/iptocurrency` |\n| Professional and above | `/timeseries`, `/fluctuation` |\n\nSee [pricing](https://currencyfreaks.com/pricing) for request quotas.\n\n## Integration notes\n\n**All numeric values are strings.** Rates, amounts and percentages are JSON-encoded as\nstrings to preserve full precision. Parse them into a decimal type rather than a float,\nparticularly for financial calculations.\n\n**`/supported-currencies` is authoritative.** Filter on `status == \"AVAILABLE\"` to\ndetermine what you can query. Use `/currency-symbols` for display labels only.\n\n**Check coverage before querying history.** Depth varies by currency, so call\n`/historical-data-limits` rather than assuming a start date.\n\n**Filter with `symbols`.** An unfiltered response spans every available currency. Passing\n`symbols` reduces both payload size and latency.\n\n**Quotas are monthly, not per-second.** There are no hourly or daily throttles, so a `429`\nmeans your plan quota is exhausted and retrying will not help. We email at 80%, 90% and\n100% usage on paid plans.\n\n**Call the API server-side.** Because the key travels in the query string, requests should\noriginate from your backend, not from browser JavaScript. Proxy through your own endpoint\nand keep the key on your server.\n\n**JSON is recommended for cryptocurrency symbol sets.** XML element names derive from\ncurrency codes, and codes containing characters that are invalid in XML names are\nnormalised. See the XML request in folder 02 for details.\n","schema":"https://schema.getpostman.com/json/collection/v2.0.0/collection.json","isPublicCollection":true,"owner":"57124893","team":31861015,"collectionId":"eb48304d-2cb0-40ba-92c1-1906e43be64c","publishedId":"2sBY4TryiX","public":true,"publicUrl":"https://documenter-api.postman.tech/view/57124893/2sBY4TryiX","privateUrl":"https://go.postman.co/documentation/57124893-eb48304d-2cb0-40ba-92c1-1906e43be64c","customColor":{"top-bar":"FFFFFF","right-sidebar":"303030","highlight":"008080"},"documentationLayout":"classic-double-column","customisation":{"metaTags":[{"name":"description","value":"Try the CurrencyFreaks exchange rate API in Postman. 1,000+ currencies, history to 1984, fiat plus crypto and metals.
