Paginating through results

Each response returns up to 10 profiles. If more profiles can be fetched for this query, the response will return a field next_page that can be passed into the api again to return more results. This behavior can be continued until there are no more results remaining.

Example

Make a request

GET https://api.b2d.ai/audience?tech=twilio&api_key=YOUR_API_KEY

If next_page exists in the response, use it to pull more results

GET https://api.b2d.ai/audience?tech=twilio&api_key=YOUR_API_KEY&next_page=NEXT_PAGE_VALUE

To receive consistent results, pass the same parameters you passed in the first query. The only parameter you should modify as you paginate through results is the next_page parameter.

Each next_page token is only valid for 30 seconds.

Data

Total Results The first request returns a field total, which is the total number of profiles matching the query

New Fields

Profiles that are returned include the following fields:

Full profile urls:

linkedin_url: the person’s linkedin url
x_url: the person’s x url
github_url: the person’s github url

Signals:

signals: signals you can use to determine the relevancy of the profile.
signals.event_types: a list of ways in which the person has interacted with the queried technologies
signals.matched_terms: a list of technologies in the query the person has interacted with
signals.number_of_event_types: the number of ways in which the person has interacted with the queried technologies
signals.ratio_of_matched_events_past_2_years: the ratio of the person’s interactions over the past 2 years that match the queried technologies
signals.ratio_of_matched_events_past_year: the ratio of the person’s interactions over the past year that match the queried technologies

Events:

events.match: whether the event matches the technologies queried. by default, only events matching the queried technologies are included. To include all events for profiles returned, include events in the include_fields parameter
events.matched_terms: technologies in the query the match the event
