Build with the evidence
Your first 5,000 API SKUs are free.
Use canonical product evidence in your app, research or workflow. API reads return existing records; catalogue scans capture fresh source evidence. Their allowances are separate. New source captures share a limited capture queue and can pause when capacity is exhausted; API reads of existing records continue.

Scanned SKU allowances limit account usage. Fresh source captures are queued within current shared capacity and are not a promise of immediate throughput. A captured record does not automatically receive a verified score. See category rules and release status →

Clear from the start.
What does a SKU mean?
A SKU is a product or variant record returned by the API or processed by your catalogue scan. API reads and scans have separate monthly allowances. The dashboard always shows the used and remaining amounts.
Is Chrome free?
Yes. Install the Chrome extension free and connect your HTT account. Your chosen account plan controls report and catalogue access; the extension installation has no separate charge.
Do I need a sales call?
No. Choose any published plan, complete secure Stripe Checkout and open your account. Connect Shopify, Wix or WordPress from the installation guide. Enterprise also checks out online.
When do I pay?
All new paid subscriptions bill annually in the selected currency. Existing subscriptions retain their agreed billing terms. The full annual total and any trial shown by Stripe are displayed before you confirm.
What happens when my SKUs run out?
Your saved evidence stays in your library. New requests stop at the allowance instead of creating surprise charges. Upgrade online or wait for the next monthly reset.
Can I cancel?
Manage billing, invoices and cancellation from your account through Stripe. Review the terms and the cancellation screen for the access end date before confirming.
Are all product categories scored in the same way?
No. Textiles use the recorded fibre methodology. Devices, ingredients and other categories require their own evidence and calibration. A missing or incomplete assessment stays unscored; payment cannot change a public score.
Does a paid plan change a brand score?
No. Paid access adds tools and capacity. Every score follows the same recorded category method and evidence rules.
