Each bot is identified\nand provided a RegExp `pattern` to match against an HTTP `User-Agent` header.\nAdditional metadata is available on each item.\n\n## Install\n\n### Direct download\n\nDownload the [`well-known-bots.json` file][raw-json-url] directly.\n\n## Realities\n\nIt's impossible to create a system that can detect all bots. Well-behaving bots\nidentify themselves in a consistent manner, usually via the User-Agent patterns\nthis project provides. It is straightforward to identify these well-behaving\nbots, but misbehaving bots pretend to be real clients and use various mechanisms\nto evade detection.\n\nFor more details, see [Non-Technical Notes in the\nbrowser-fingerprinting][non-tech-notes-url] project.\n\n## Structure\n\nEach entry in the JSON represents a specific bot or crawler and includes the following fields:\n\n- id: A unique identifier for the bot\n- categories: An array of categories the bot belongs to (e.g., \"search-engine\", \"advertising\")\n- pattern: A regular expression pattern used to identify the bot in user agent strings\n- url: (optional) A URL with more information about the bot\n- verification: A list of supported methods for verifying the bot's identity (if the bot is not verifiable it should be empty).\n- instances: An array of example user agent strings for the bot\n- aliases: Extra unique identifiers for the bot that can be used to identify it across other data sources\n\n### Verification\n\nEach verification entry contains the following fields:\n\n- type: The method of verification (`dns` and `cidr` are supported)\n\nIf you specify `dns` verification then these fields are expected:\n\n- masks: An array of mask patterns used for verification\n\nIf you specify `cidr` verification then these fields are expected:\n\n- sources: An array of sources to pull cidr range data from (at least one is required)\n\n### Verification mask patterns\n\nThe mask patterns use the following special characters:\n\n- *: Represents 0 or 1 of any character\n- @: Acts as a wildcard, matching any number of characters\n\nAll other characters in the mask require an exact match.\n\n### Cidr verification sources\n\nEach cidr source requires the following fields:\n\n- type: The type of source (Currently only `http-json`) is supported\n- url: The url that hosts the ip ranges\n- selector: A JsonPath selector that selects all of the IP ranges in the source \n\n## License\n\nThe project is a hard-fork of [crawler-user-agents][forked-repo-url] at commit\n`46831767324e10c69c9ac6e538c9847853a0feb9`, which is distributed under the [MIT\nLicense][mit-license].\n\n[raw-json-url]: https://raw.githubusercontent.com/arcjet/well-known-bots/main/well-known-bots.json\n[forked-repo-url]: https://github.com/monperrus/crawler-user-agents/commit/46831767324e10c69c9ac6e538c9847853a0feb9\n[non-tech-notes-url]: https://github.com/niespodd/browser-fingerprinting/blob/baecc60821cefd06eb89a54d18be39d87dd16f2e/README.md#non-technical-notes\n[mit-license]: https://opensource.org/licenses/MIT\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farcjet%2Fwell-known-bots","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Farcjet%2Fwell-known-bots","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farcjet%2Fwell-known-bots/lists"}
