Event API is in Beta
Please use with the understanding that parameters and response data formats may change to support usage feedback.

The Event API returns information on an event like a webinar, meetup, etc. and can be used to extract clean event details, text descriptions and other data from online and in-person event pages for standalone events held within a single day.

Most popular event aggregation sites are supported, but the Event API is a new release so please make sure to report any bugs you find to support@diffbot.com.

Support for multi-day, multi-track events (i.e. full conference schedules and festivals), is planned but not yet supported.

Test drive Event API without a token at diffbot.com/testdrive.

Response

The Event API returns data in JSON format.

Each response includes a request object (which returns request-specific metadata), and an objects array, which will include the extracted information for all objects on a submitted page.

Objects in the Event API's objects array will include the following fields:

Field	Description
`type`	Type of object (always `event`).
`pageUrl`	URL of submitted page / page from which the event is extracted.
`resolvedPageUrl`	Returned if the `pageUrl` redirects to another URL.
`title`	Title of the event.
`startDate`	Start date of extracted event in GMT, normalized in most cases to RFC 1123 (HTTP/1.1). If no start time was found, the time is midnight.
`endDate`	End date of extracted event in GMT, normalized in most cases to RFC 1123 (HTTP/1.1). If no end time was found, the time is midnight.
`startDateLocalTimezone`	Start date of extracted event in the local timezone as deplayed on the page. If no start time was found, the time is midnight.
`endDateLocalTimezone`	End date of extracted eventin the local timezone as deplayed on the page. If no start time was found, the time is midnight.
`timezoneOffset`	GMT offset in hours and minutes.
`description`	Text description, if available, of the event.
`venue`	The name of the venue, if available.
`location`	Parsed location information, if a parsable location was found.

↳`longitude`	Longitude of the geographic coordinate of the address.
↳`postalCode`	Postal code.
↳`region`	Region, such as a state or province.
↳`precision`	The scale of the area described by the address. More specific addresses describe a smaller area and will have a lower value.
`images`	Array of images, if present within the event page.
↳`url`	Fully resolved link to image. If the image `SRC` is encoded as base64 data, the complete data URI will be returned.
↳`title`	Description or caption of the image.
↳`height`	Height of image as (re-)sized via browser/CSS.
↳`width`	Width of image as (re-)sized via browser/CSS.
↳`naturalHeight`	Raw image height, in pixels.

`meta`	Returns a top-level object (`meta`) containing the full contents of page `meta` tags, including sub-arrays for OpenGraph tags, Twitter Card metadata, schema.org microdata, and -- if available -- oEmbed metadata.
`diffbotUri`	Unique object ID. The `diffbotUri` is generated from the values of various event fields and uniquely identifies the object. This can be used for deduplication.
`tags`	Array of tags/entities, generated from analysis of the extracted `title` and `text` fields. Tags are extracted by the Diffbot Natural Language API and linked to the Diffbot Knowledge Graph. Tags will be returned if the text is in one of the following languages: English (en), French (fr), Spanish (es), Chinese (zh), German (de), Russian (ru), Japanese (ja), Dutch (nl), Polish (pl), Norwegian (no), Danish (da), Swedish (sv), Italian (it).

↳`score`	Rating of the entity's relevance to the overall text content (range of 0 to 1) based on various factors.
↳`rdfTypes`	If the entity can be represented by multiple resources, all of the possible URIs will be returned.
↳`uri`	Link to the primary Diffbot entity for this tag in the Diffbot Knowledge Graph.
`categories`	Array of categories, generated from analysis of the extracted `title` and `text` fields. This field is available for over 100 languages. The complete list of categories can be found at this link.
↳`name`	Name of the category.
