Influencer Audience Overlap API

Is there an API to compare audience overlap between creators?

Yes. The Influencers.club Audience Overlap endpoint takes 2–10 creators on the same platform and returns total followers, unique followers and pairwise overlap percentages — so you can see how much reach you’d actually be buying twice before booking creators together.

curl -X POST https://api-dashboard.influencers.club/public/v1/creators/audience/overlap/ \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"platform": "instagram", "creators": ["mrbeast", "khaby00"]}'
