Prism Audience Overlap API

Returns how much two TikTok creators' commenting audiences overlap: shared people, an overlap score, counts unique to each, and a confidence label.

GET /v1/prism/audience-overlap

When to use the Prism Audience Overlap API

Use it to check for duplicate reach before booking both creators, since no single endpoint compares two creators' audiences.

From the API reference

Samples each creator's recent videos and their commenters, then computes a deterministic audience-overlap: shared commenters, Jaccard index, a/b-only counts, and an honesty confidence label (commenters over-index super-fans: a lower bound, never full-audience truth). TikTok-only in v1 (YouTube/Instagram are a fast-follow); a non-tiktok platform is rejected. If either creator can't be fetched the overlap is undefined → full refund.

Prism API

What can you do with the Audience Overlap API?

The Audience Overlap endpoint gives you structured Prism data with computed fields in a single request. No scraping infrastructure to build or maintain.

Example Request

# GET /v1/prism/audience-overlap: 20 credits per call. Cache hits are free and failed calls are refunded.
# Check the price first for 0 credits: add dry_run=1 to the query. Nothing is fetched or charged.
# --max-time 60: the API's own time limit for this endpoint.
# --retry 3: retries timeouts, 429 and 5xx, honoring Retry-After.
# -o response.json keeps only the final attempt's body.
# One Idempotency-Key per request, reused on every retry, so a retried call is never charged twice.

What is the SocialCrawl Audience Overlap API (Prism Audience Overlap)?
GET /v1/prism/audience-overlap takes two TikTok handles (handle_a and handle_b) and measures how much their commenter audiences overlap. It returns a Jaccard index, the shared-fan count, and a confidence label, computed from each creator's real commenters rather than a follower estimate.
How is the overlap computed?
The endpoint samples commenters from each creator's recent videos, intersects the two sets, and reports the Jaccard index (shared over combined) plus the raw shared-fan count. It is set math on real commenters, with no LLM in the calculation.
What do videos_per_creator and depth control?
videos_per_creator sets how many recent videos to sample per handle, and depth sets how deep to pull commenters from each. Larger values widen the sample and raise the confidence label, at the cost of more work per call.
How much does an audience-overlap call cost?
Each call is a flat 20 credits covering both creators' sampling and the overlap math. New accounts get 100 free credits with no credit card. If a strict majority of the legs fail, part of the cost is refunded automatically, and if all legs fail the full 20 credits come back.
Why measure commenter overlap instead of follower counts?
Follower counts tell you reach, not whether two audiences are the same people. Commenter overlap shows the real engaged-audience intersection, so brands can spot redundant creator pairs or complementary ones before booking a collaboration. One call does the sampling and set math for you.
