Frequently Asked Questions

What can my organization do with your API?

Bitext’s API is focused on the key operations for market research specialists: sentiment analysis, categorization, entity extraction and concept extraction.

Our customers typically use these online services to understand what the market is saying about their brands, products and services:

  • actively listening to social media mentions,
  • analyzing surveys and Voice of the Customer tools,
  • or analyzing ratings and reviews from their web sites or third-party services.

Many of our customers are online services or market research agencies that integrate our API into their own offering, adding even more value to their services.

How is the API priced?

The monthly cost of our Standard Plan is 199€, which allows you to process up to 50 MB of text (around 500,000 sentences) for one language. For other plans, please contact us.

You can easily sign up for a 30-day free trial account of our public API. When you are ready to purchase your Standard Plan, please check with us or use our purchase form.

If, after evaluating our Public API, you feel that it does not fully meet your requirements, you might benefit from our customization services. Contact us to learn more about how other customers extract all the potential from our linguistic technology through customized dictionaries and ad-hoc categorization schemes, tailored to their business needs.

What languages are available?

Currently, our text analysis API can work with English, Spanish, French, Portuguese, Italian, German, Dutch and Catalan.

Other languages such as Russian or Basque are currently in beta stage and will be updated soon.

What are the usage limits of the free trial account?

Bitext subscriptions are always free for 30 days, with 50 MB of usage, no credit card required.

Paid and Trial subscriptions enable 50 MB of text analysis requests/month. If you need an upgrade, please contact us.

Currently the limit of characters per API call is of 1000. We are working to increase that limit and we will do so promptly.

Do you offer a free version for public-interest or academic projects?

Public-interest projects, qualified nonprofits, students and academic institutions should contact us with details about their project’s needs and objectives. Requests will be evaluated on a case-by-case basis.

Where can I find the API's technical reference docs?

Please remember to check the Quick Start Guide and the code samples.

Is there technical support? If so, which kind of support is provided?

Customers with a paid plan can view dedicated support contact information on their user dashboard.

Email is the preferred method to contact our support team. Telephone or video-conferencing can be arranged for specific issues. Support is provided during our normal business hours.

24×7, priority support and project-specific SLAs are quoted on a case-by-case basis.

Please remember to check the Quick Start Guide and the code samples.

How are payments made? Can I get an invoice?

Most customers use our integration with PayPal to process their payments.

Payment via wire transfer can be arranged for those organizations unable to perform online payments. Please notice that this option could imply delays in account provisioning or service interruptions.

All API packages are invoiced. VAT might be added for applicable customers, as per Spain and EU’s tax laws.

Contact us if you have a specific request about method of payment or invoicing.
