What this product checks
Request the Threads account signal explicitly. Do not infer a Threads result from an Instagram check, even when the same phone number is used.
Reading the result
A conclusive yes or no describes the account signal at the time of checking. Unknown means no conclusive answer; it must not be treated as no. A registration signal does not verify identity, consent or message delivery.
Where teams use Threads checks
- Measure how many contacts in a list are on Threads, next to Instagram.
- Re-check the same list over time to follow Threads adoption in your customer base.
- Keep Threads as its own result column in bulk exports.
Cost example for Threads
−40%
1,000 valid unique numbers from one country cost $0.30 at the bulk price ($0.0003 each). A country with only 300 numbers is still checked and is billed as the minimum number of checks: $0.15. Checking the 1,000 numbers one by one at the single-check price would cost $0.50.
This is the cost shown before you submit. Duplicates and invalid rows are removed first; a completed list is charged this amount, unknown results included, and a failed list is refunded in full.

How much does each Threads check cost?
$0.0005 per single check, in real time. In a bulk task each country is its own group at $0.0003 per check; a country with only a few numbers is billed as the minimum number of checks. A group is charged in full once its batch completes, unknown rows included, and refunded if the batch fails.
Is an unknown Threads result charged?
Not in a single check: only a conclusive answer is charged. In bulk, yes: each country is charged in full once it completes, unknown rows included; a list that fails is refunded. Invalid rows and duplicates cost nothing.
Can I check Threads through the API?
Yes. Send POST /api/v1/checks with the product ID threads for one input, or POST /api/v1/bulk-jobs with a file for a list.
