First time? Set up Authentication

Learn how to authenticate your API requests with your API key.
Search the Kalent talent database using a combination of filters. Each filter targets a specific attribute (job title, location, skill, etc.) and can be marked as required, excluded, or exact-match. Results are ranked by best overall match.

​
Request body

​
filters
object[]
required
Array of filter objects. Each object must include a filterType discriminator, a value, and modifier flags.Every filter accepts the following common fields:
​
relatedSearchTransactionIds
string[]
Array of searchTransactionId values from previous search responses. When provided, talents that were returned in those previous searches are excluded from the current results. Use this field for pagination: after each search, collect the searchTransactionId from the response and include it (along with any earlier ones) in your next request to receive fresh, non-overlapping results. See Pagination below.

​
Pagination

The search API uses a transaction-based pagination model instead of traditional page numbers.

​
How it works

  1. First request — call the endpoint with your filters. The response includes a searchTransactionId and up to 10 matching talents.
  2. Next page — send the same filters again, but add the previous searchTransactionId to the relatedSearchTransactionIds array. The API will exclude all talents that were already returned and give you the next batch.
  3. Subsequent pages — keep accumulating searchTransactionId values in the array. Each new request excludes all talents from every prior transaction.
# Page 1
curl -X POST https://app.kalent.ai/api/v1/search/talents \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{
    "filters": [
      { "filterType": "JOB_TITLE", "value": "Software Engineer", "isRequired": true, "isExcluded": false, "isExactMatch": false }
    ]
  }'
# → response includes "searchTransactionId": "tx_aaa111"

# Page 2
curl -X POST https://app.kalent.ai/api/v1/search/talents \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{
    "filters": [
      { "filterType": "JOB_TITLE", "value": "Software Engineer", "isRequired": true, "isExcluded": false, "isExactMatch": false }
    ],
    "relatedSearchTransactionIds": ["tx_aaa111"]
  }'
# → response includes "searchTransactionId": "tx_bbb222"

# Page 3
curl -X POST https://app.kalent.ai/api/v1/search/talents \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{
    "filters": [
      { "filterType": "JOB_TITLE", "value": "Software Engineer", "isRequired": true, "isExcluded": false, "isExactMatch": false }
    ],
    "relatedSearchTransactionIds": ["tx_aaa111", "tx_bbb222"]
  }'
Non-deterministic results — Search results are not guaranteed to be identical across requests, even with the same filters. This is by design:
  • Real-time profile refresh: talent profiles are enriched and updated in real time during search. A profile that did not match a filter moments ago may match now (and vice versa) after a refresh.
  • AI-powered scoring: result ranking uses AI models whose outputs can vary slightly between calls.
  • Database updates: new talents are continuously indexed and existing profiles are updated from external sources.
The relatedSearchTransactionIds mechanism guarantees that you will not see the same talent twice across paginated requests, but the total pool of matching talents may shift between calls. This is inherent to a live, AI-augmented search engine and does not affect result accuracy — every returned talent genuinely matches your filters at the time of the request.Read more in the Non-deterministic Results guide.
