The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## UUID Generator Generate **UUID v1, v3, v4, v5** instantly for testing, unique IDs, API tokens, and database seeding. No coding needed – just select version, hyphen format, and optionally provide **name** and **namespace** for v3/v5. Get results via Dataset, Key-value store `OUTPUT`, or API. Fast, scalable, free trial. ### Why Use UUID Generator? - **Instant IDs**: Single-click generation for dev workflows. - **Multiple versions**: Random (v4), time-based (v1), deterministic (v3/v5). - **Deterministic support**: Use `name` and `namespace` for repeatable v3/v5 UUID generation. - **Apify platform**: Schedule runs, API access, monitoring, integrations. - **Export ready**: JSON/CSV download, perfect for test data. ### Features - Generate v1 (time-based), v3 (MD5 hash), v4 (random), v5 (SHA-1 hash). - Hyphen on/off formatting. - Optional `name`, `namespaceType`, and `namespace` inputs for v3/v5. - Free trial covers hundreds of runs. - Run via API, schedule, or webhook. ### Input Options Click the [input tab](#input) for full schema. | Field | Type | Description | Default | | --------------- | ------- | -------------------------------------------------------------- | ---------------------------------------- | | `version` | Select | UUID version: v1, v3, v4, v5 | `v4` | | `hyphen` | Boolean | Include hyphens (-) | `true` | | `name` | String | Used for v3/v5. Same name + same namespace = same UUID | `"default-name"` | | `namespaceType` | Select | Namespace type for v3/v5: `DNS`, `URL`, `custom` | `DNS` | | `namespace` | String | Custom namespace UUID, used only when `namespaceType = custom` | `"6ba7b810-9dad-11d1-80b4-00c04fd430c8"` | **Notes:** - `name`, `namespaceType`, and `namespace` are mainly used for **v3** and **v5**. - For **v1** and **v4**, those fields are ignored. - For **v3/v5**, the same `name` and `namespace` will always generate the same UUID. **Example input (v4):** ```json { "version": "v4", "hyphen": false } ```` **Example input (v3 + custom namespace):** ```json { "version": "v3", "hyphen": true, "name": "my-user-id", "namespaceType": "custom", "namespace": "6ba7b810-9dad-11d1-80b4-00c04fd430c8" } ``` **Example input (v5 + DNS namespace):** ```json { "version": "v5", "hyphen": false, "name": "example.com", "namespaceType": "DNS" } ``` ### Output Data Results saved to **default Dataset** (export JSON/CSV) and **Key-value store `OUTPUT`**. #### Output Table | Field | Type | Description | Example | | --------------- | ------- | ------------------------------ | ------------------------------------ | | `uuid` | String | Generated UUID | `"550e8400e29b41d4a716446655440000"` | | `version` | String | Used version | `"v4"` | | `hyphen` | Boolean | Hyphen setting | `true` | | `createdAt` | String | ISO timestamp | `"2026-03-17T05:37:00Z"` | | `name` | String | Provided name for v3/v5 only | "example.com" | | `namespaceType` | String | Namespace type for v3/v5 only | "DNS" | | `namespace` | String | Namespace value for v3/v5 only | "DNS" | **Example output (v4):** ```json { "uuid": "550e8400-e29b-41d4-a716-446655440000", "version": "v4", "hyphen": true, "createdAt": "2026-03-17T05:37:00.000Z" } ``` **Example output (v5 + DNS namespace):** ```json { "uuid": "cfbff0d1-9375-5685-968c-48ce8b15ae17", "version": "v5", "hyphen": true, "createdAt": "2026-03-17T05:37:00.000Z", "name": "example.com", "namespaceType": "DNS", "namespace": "DNS" } ``` ### How to Use UUID Generator 1. **Run Actor** (default generates v4 with hyphens). 2. **Customize** via input: select version, toggle hyphen. 3. For **v3** or **v5**, optionally provide `name`, `namespaceType`, and `namespace`. 4. If using `custom` namespace, provide a valid namespace UUID. 5. **Download** Dataset (JSON/CSV) or fetch `OUTPUT` via API. 6. **Schedule/API** for automation. > 💡 **Quick test**: Run now – get UUID in seconds! ### Pricing - **Free trial**: ~$5 credits = thousands of UUIDs. - **Pay-per-run**: Low CU usage (minimal compute). - Scales to millions of IDs without extra cost. ### Tips - **v4**: Default for random unique IDs. - **v1**: Useful when you want time-based UUIDs. - **v3**/**v5**: Deterministic – same input = same UUID. - **No hyphen**: Compact 32-char format for URLs. - **API**: `curl` or SDK for batch generation. ### FAQ #### Is UUID Generator free? Free trial covers extensive testing. Production: pay-per-compute (very low). #### v3 vs v5? v3 (MD5): Legacy. v5 (SHA-1): Modern deterministic. #### Why do v3 and v5 need name and namespace? Because v3 and v5 are name-based UUIDs. The same name and namespace combination always produces the same UUID. #### Legal to use? UUIDs are standard – generate unlimited test data ethically. *** **Feedback?** [Create issue](https://apify.com/apizy/uuid-generator/issues/open) – open to suggestions! # Actor input Schema ## `version` (type: `string`): UUID version (v1/v3/v4/v5) ## `hyphen` (type: `boolean`): Include hyphens in the UUID ## `name` (type: `string`): Used only for v3 and v5.
