Frequently Asked Questions

What is the PQAI API?

It provides programmatic access to PQAI’s AI-powered patent search engine and allows integration of PQAI functionality in other software platforms.

Do I need the API?

If you’re just looking to perform patent searches, you can use the PQAI web search for free. The API is useful if you need programmatic access, bulk searches, or integration into your own systems.

How do I subscribe to the PQAI API?

You can subscribe by choosing either the PQAI+ Individual Plan ($20/month) or the Enterprise Plan ($700/month) based on your needs.

What’s included in the $20/month plan?

The PQAI+ Individual Plan includes:

  • 1,500 search requests per month
  • 2 searches per minute
  • Access to all standard PQAI features (prior-art search, CPC classification, concept extraction, etc.)
  • Personal use only (not for commercial integration)

Who should use the Enterprise Plan ($700/month)?

The Enterprise Plan is designed for:

  • Individuals needing more than 1,500 searches per month.
  • Businesses integrating PQAI into commercial platforms.
  • Users who require bulk data access, higher rate limits, and faster API performance.

What happens if I exceed my request limit?

We’ll notify you via email when you reach 90% of your usage limit. If you need additional credits, contact us to discuss an upgrade.

Can I increase my rate limit?

Yes. If you need a higher request rate, upgrading to the Enterprise Plan will increase your limit to 5 searches/min. If you need even higher limits, contact us for a custom plan.

Can I store PQAI search results in my own database?

Yes. However, please refer to our Terms of Use for more details on data storage and usage policies.

Can I integrate PQAI into my own software or platform?

Yes, but you’ll need an Enterprise Plan ($700/month) for commercial use.

Do you offer API documentation?

Yes! You can access our API documentation here: PQAI API Docs.

How do I contact support?

For Individual Plan users: Support is available via Help Docs and Email Helpdesk at [email protected].
For Enterprise Users: Priority support is provided via Email & Dedicated Assistance.

Is the PQAI API secure?

Yes, PQAI uses secure authentication and follows industry best practices for data security.
PQAI is a collaborative initiative to improve the patenting process by developing tools that enable better prior-art search and analysis.
