Pricing

Grammar Check API

Our Grammar Check API is priced according to the number of words you process, with different tiers offering lower rates for higher usage. As you process more words, you'll move to higher tiers, resulting in a lower cost per word.

Pricing Structure

TierNumber of WordsCost/Word (USD)Cost/Word (USD) with Sensitive Data

Tier 2 - Tier 5Over 2,000,000

Sample Pricing Calculations:

Tier Based Pricing:

The first 2 million words you process will be billed at Tier 1, and once you cross the 2 million threshold, the remaining words till you cross a total usage of 10 million words will be billed at Tier 2 pricing, and so on. Assume you have processed 2,005,000 words in a month. Here, the first 2,000,000 words would be priced as per Tier 1 and the remaining 5,000 words will be priced as per Tier 2. In this case, the total cost will be calculated as below:

  1. When "is_sensitive_data" set to "false" - 2,000,000 X 0.0002 (Tier 1) + 5,000 X 0.00012(Tier 2) = $400.6

  2. When "is_sensitive_data" set to "true" - 2,000,000 X 0.00025 (Tier 1) + 5,000 X 0.00020 (Tier 2) = $501

Note 1 - This calculation assumes that you have maintained the same sensitive data parameter to either true or false, for the entire month. If you change the is_sensitive_data parameter, during the month, the final price will be different and will depend on the usage accumulated under each parameter.

Note 2 - The values used in the above examples are arbitrary. For actual prices, please refer to the pricing table.

Monthly Billing:

Your billing amount is calculated according to the words consumed every month starting 1st of the month.

For example, as of January 3, 2024, you had processed 15 million words, which placed you in Tier 3. Continuing your usage, you use 10 thousand words on February 1, 2024. In this case, your pricing tier would be re-set and the 10,000 words used in July will be priced as per Tier 1. The total cost calculation will be as follows:

  1. When "is_sensitive_data" set to "false":

For the month of June - 2,000,000 X 0.0002 (Tier 1) + 10,000,000 X 0.00012(Tier 2) + 5,000,000 X 0.00006 (Tier 3) = $1,900

For the month of July - 10,000 X 0.0002 (Tier 1) = $2

Total cost for June and July = $1,900 + $2 = $1,902

  1. When "is_sensitive_data" set to "true":

For the month of June - 2,000,000 X 0.00025 (Tier 1) + 10,000,000 X 0.00020 (Tier 2) + 5,000,000 X 0.000195 (Tier 3) = $3,475

Fort the Month of July - 10,000 X 0.00025 (Tier 1) = $2.5

Total cost for June and July = $3,475 + $2.5 = $3,477.5

Note 1 – This calculation assumes that you have set the same sensitive data parameter, either true or false, for the entire month. If you change the sensitive data parameter during the month, the final price will be different and will depend on the usage accumulated under each parameter.

Note 2 - The values used in the above examples are arbitrary. For actual prices, please refer to the pricing table.

Word Count Usage Calculation Logic

Usage will be calculated based on the number of words processed using the Grammar Check API. Word count usage is calculated using the rules stated below:

  • A word is defined as a continuous string of characters surrounded by whitespaces.
  • Whitespaces and newline characters are not counted as words.
  • Standalone numbers and alphanumeric strings are counted as words. For example,
    • "3" → 1 word
    • "34" → 1 word
    • "35 and 45" → 3 words
    • "ANI25" → 1 word
  • Few more standalone examples,
    • “I want to write a letter.” → 6 words
    • “I live 90 miles away.” → 5 words
    • “Hey! How are you?” → 4 words
    • “Back-end and front-end.” → 3 words
  • If you process the same sentence twice, the word count will be calculated twice and your usage will be billed accordingly. For eg. if you process the following:
    • Request 1 - "He plays football like a pro. People like to watch him."
    • Request 2 - "He plays football like a pro. People enjoy watching him."
    The sentence "He plays football like a pro." will be counted twice. The total words processed in both the requests together will be 21.

Prepaid and Postpaid Pricing

All accounts, by default, require an amount to be deposited against which the API is consumed. As per the usage, the amount from your account will be deducted in real-time. Once you exhaust the amount, API usage will stop providing a response unless you top up your account. You can choose to top up the amount manually or set up a smart top-up on your account at your convenience.

We also provide a post-paid pricing model for large enterprise accounts. For post-paid pricing, please reach out to sales@trinka.ai

Usage Tracking

After generating an API key, you can track your usage in the Dashboard and Usage Analytics sections. Usage is updated in real time; however, the available balance is updated every hour. Below are some details regarding usage tracking:

  1. You can analyze usage on both Test and Production keys.

  2. The information displayed on the Dashboard will show your usage in the last 30 days.

  3. To view information about usage over specific time periods, you can set appropriate filters on the Usage Analytics page.

  4. From the Usage Analytics section, you can download a CSV file containing the usage records for a specific time period of your choice.

  5. Since the balance is updated every hour, you might see a negative balance in your account. In such a situation, you can add balance to your account to continue usage.

Pricing Tiers will be the same for both pricing models. Secondly, for both models, tiers will be reset at the start of the calendar month.

Sensitive Data Plan

Trinka's Sensitive Data Plan is designed for Enterprises seeking the utmost security, preferring their organizational data not to be stored on our servers. With this plan, content submitted for grammar checking is not permanently saved; it is automatically removed from all our systems once processing is complete. Consequently, your content is not utilized for AI training to enhance our systems, guaranteeing maximum confidentiality for your sensitive information.
