  -H "Content-Type: application/json" \
  -d '{"findBy":"query","query":["UCUyeluBRhGPCW4rPe_UvBZQ","UCX6OQ3DkcsbYNE6H8uQQuVA"],"mode":"standard"}'

Body parameters:

Name	Type	Required	Default	Description

Scan Workflow

Scans run asynchronously. Here's the typical flow:

Start a scan with POST /scan - returns a scan ID and status Queued
Poll for status with GET /scan/{id} - status progresses: Queued → Running → Completed
Search results with GET /search/outliers?referenceId={scanId} - returns discovered outlier videos

bash

# 1. Start scan
SCAN_ID=$(curl -s -X POST "https://public-api.tubelab.net/v1/scan" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":["minecraft","gaming"],"mode":"fast"}' | jq -r '.id')

# 2. Poll until complete
curl -s "https://public-api.tubelab.net/v1/scan/$SCAN_ID" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY" | jq '.status'

# 3. Search results once completed
curl -s "https://public-api.tubelab.net/v1/search/outliers?referenceId=$SCAN_ID" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

Mode	Outliers Limit	Channels Limit	Cost	Est. Time
Fast	1,000	100	50 credits	30 min – 2 hrs
Standard	2,500	250	100 credits	2 – 4 hrs

Common Patterns

Pagination

Search endpoints return pagination.total, pagination.from, and pagination.size. Use from and size query params to paginate:

bash

# Page 1 (items 0-19)
curl -s "https://public-api.tubelab.net/v1/search/outliers?query=minecraft%20adventures&type=video&from=0&size=20" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

# Page 2 (items 20-39)
curl -s "https://public-api.tubelab.net/v1/search/outliers?query=minecraft%20adventures&type=video&from=20&size=20" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

Range Filters

Many numeric fields support From/To suffixes for range filtering:

bash

# Channels with 10k-100k subscribers and avg views > 5000
curl -s "https://public-api.tubelab.net/v1/search/channels?query=cooking%20healthy%20recipes&subscribersFrom=10000&subscribersTo=100000&averageViewsFrom=5000" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

Sorting

Use sortBy and sortOrder params. Available sort fields vary by endpoint.

Important: When using query, omit sortBy to get the default relevance-based ranking. Adding a sort like sortBy=views overrides relevance and returns results ordered by that field, which usually produces worse matches. Only add sortBy when you don't use query (e.g. filter-only searches).

bash

# Filter-only search (no query) — sorting makes sense here
curl -s "https://public-api.tubelab.net/v1/search/outliers?type=video&classificationQuality=positive&sortBy=views&sortOrder=desc" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

Array Parameters

Array params use repeated keys:

bash

# Multiple search queries
curl -s "https://public-api.tubelab.net/v1/search/channels?query=minecraft%20adventures&query=gaming%20tutorials" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

Search Recipes

Ready-to-use filter combinations for common research tasks. Date filters use ISO 8601 format - compute relative dates with date or substitute directly.

Tip - queries: Search is semantic — longer, descriptive queries return much better results than single keywords. Use query=minecraft adventures or query=cooking healthy recipes instead of just query=minecraft or query=cooking. Think 2-4 words that describe the niche.

Tip - sorting: When using query, do NOT add sortBy — the default sort is by relevance and gives the best matches. Only use sortBy for filter-only searches (no query), e.g. sorting by foundAt or views.

Tip - averageViewsRatio: When searching outliers, prefer averageViewsRatioFrom=1 to find videos that outperformed the channel's average. A ratio of 2 means the video got 2x the channel's usual views. Values above 5 are very rare and indicate extreme virality - only use higher thresholds when you want to narrow results significantly.

Tip - content type: When searching outliers, prefer type=video to focus on long-form videos. Shorts tend to have inflated view counts and skew results. Only use type=short when specifically researching short-form content.

Profitable channels (recently found)

Monetized channels found in the last year with estimated monthly revenue above $1,000 and at least 1,000 subscribers. Sorted by discovery date.

bash

ONE_YEAR_AGO=$(date -u -d "1 year ago" +%Y-%m-%dT00:00:00Z 2>/dev/null || date -u -v-1y +%Y-%m-%dT00:00:00Z)
curl -s "https://public-api.tubelab.net/v1/search/channels?monetizationAdsense=true&revenueMonthlyEstimationFrom=1000&subscribersFrom=1000&publishedAtFrom=$ONE_YEAR_AGO&language=en&language=de&language=fr&excludeNiche=music&excludeNiche=song&excludeNiche=lofi&excludeNiche=movies&excludeNiche=kids&excludeNiche=news&excludeNiche=politic&sortBy=foundAt&size=20" \
  -H "Authorization: Api-Key $TUBELAB_API_KEY"

Trending channels

Channels with high engagement (avg views/subscribers ratio above 1) and at least 10,000 average views, found in the last 6 months. Good for spotting rising creators.

bash

SIX_MONTHS_AGO=$(date -u -d "6 months ago" +%Y-%m-%dT00:00:00Z 2>/dev/null || date -u -v-6m +%Y-%m-%dT00:00:00Z)
