You warrant that you have all necessary rights to use and licence the Licensee Brand Assets to us as provided for in this clause.


6.1. Scope of licence. Except to the extent expressly permitted under the Terms, or unless you have received prior written authorisation from what3words, the licences granted under Clause 4 above are conditioned on your adherence to all of the restrictions below.

6.2. Access Restrictions.

a. API Requests. You must make API Requests by using http://api.what3words.com/.

c. Your Product. You will ensure that all employees and contractors who use the API, as well as any third parties who use Your Products (including the end users of any business to which you supply Your Product), are subject to terms and conditions which are consistent with these Terms. You shall be responsible for and monitor their compliance with these Terms and enforce the same against such third parties where they are in breach.

6.3. General Restrictions

a. Replicating our products. You shall not use the API for any application that replicates or attempts to replace the essential user experience of, or which functions substantially the same as, the API or any other product or service offered by what3words. In particular, you must not allow any user to reverse-engineer a 3 Word Address Location from a 3 Word Address and you must not display a 3 Word Address alongside a 3 Word Address Location.
b. Circumventing API Requests. You must not pre-fetch, cache, index, copy, re-utilise, extract, incorporate, store (including in a database) or utilise any what3words Data or the API (or any part thereof) in any way that means you are effectively circumventing making an API Request, or enabling a third party to circumvent making an API Request (including any potential API Requests).
c. Data storage by you. You may store what3words Data solely for the purpose of improving the performance of Your Product provided that such storage: (i) is temporary (and in no event lasts for more than 30 calendar days), (ii) is limited to an amount of what3words Data which is strictly required to achieve such purpose, (iii) is secure, and (iv) shall in no event enable you or a third party to use the what3words Data outside of Your Product, in any way, or to re-utilise or extract such data. If you are storing what3words Data in accordance with this Clause 6.3(c) and this means you already have the 3 Word Address Location of a particular 3 Word Address (or vice versa), you shall still make an API Request.
d. IP infringement. You shall endeavour to prevent any infringement of the what3words’ Intellectual Property Rights in the API, what3words Data and/or Brand Assets by any users (including customers) of Your Products , and shall promptly report to what3words any such infringement, or potential infringement, that comes to your attention.
e. Autosuggest and error correction. You may not incorporate any error correction, autosuggest or autocomplete technology to interoperate with the API in any of Your Products, unless such technology is provided to you by what3words or its use is expressly permitted in writing by what3words.
f. Immoral, illegal or criminal purposes. You may not use the API for immoral or illegal purpose, nor for any other purpose which may be determined by us to be threatening, abusive or harmful, or in any manner which might reasonably be considered to injure, tarnish, damage or otherwise negatively affect the reputation and goodwill associated with the what3words brand. For the avoidance of doubt, this includes utilising the API in respect of criminal activity or in contravention of any regulation or laws.
g. Security. You may not access our API in any manner that: (i) compromises, breaks or circumvents any of our technical processes or security measures associated with the API, including the creation or transmission of any virus, worms, trojan horse, cancel-bot or any other destructive or contaminating program, (ii) poses a security vulnerability to customers or users of the API, or (iii) tests the vulnerability of our systems or networks.
h. Use limitation. Except as expressly authorised under these Terms, you may not copy, rent, lease, sell, transfer, assign, sub-license, disassemble, reverse engineer or decompile (except to the limited extent expressly authorised by applicable law), modify or alter any part of the API. Insofar as you use the API for any of the purposes set out here, what3words confirms that such use is outside of the scope of any licence granted here.
i. Attribution. You agree to ensure that any references to what3words and/or the functions provided by the API in Your Product, or in any other material to be seen by end users and potential end users, shall follow the brand guidelines as published on our website from time to time.
j. Newest version. You agree to at all times use the most recent version API. However, what3words acknowledges that third parties (including end users of Your Products) may, on occasion, be using previous versions of the API where they have failed to install the latest update to your products (in such cases where Your Product is a compiled downloadable application) on their device.
k. Nearest Place. You may not display the “nearest place” information ascertainable from the API in Your Products (or any other product or service) unless you display it alongside a 3 Word Address.

6.4. Facilitation Period. As an exception to Clauses 6.3(a) and 6.3(c) above, if you have been granted a limited facilitation period, as notified to you by what3words in writing, you may be entitled to pass on the latitude/longitude coordinates derived from a 3 Word Address to your delivery drivers strictly in order to facilitate deliveries to your customers (the “Facilitation Period”). This exception shall automatically expire 6 months from the date of what3words’ written notification of its grant, at which point you shall no longer pass on the aforementioned latitude/longitude coordinates and all of the restrictions set out in Clauses 6.1 shall apply without any exception. what3words also expressly reserves the right to automatically terminate the Facilitation Period with you at any time by notifying you in writing (email will suffice) and/or by amending the Terms from time to time. Other than the foregoing, this Agreement shall continue to apply in its entirety and the Facilitation Period is subject to your continued compliance with these Terms.


7.1. Free Plan. Any person is entitled to sign up to our free usage plan which allows for up to 1,000 convert-to-coordinates requests per Month (the “Free Plan”).

7.2. NGO & Charity Plan. If you are an NGO or a charity, you may be entitled to use the API for free up to 75,000 convert-to-coordinates requests per Month (the “NGO & Charity Plan”). what3words’ prior written approval (an email from what3words’ CEO or COO will suffice) is required for usage under the NGO & Charity Plan. Please contact us for more information as to whether you are eligible. You may remain on this plan for as long as you remain an NGO or charity.

7.3. Business Plan. If you wish to use the API for a greater volume of convert-to-coordinates requests than permitted under our Free Plan, you may sign up for one of our paid plans, which allow volumes of convert-to-coordinates requests as set out here (each, a “Business Plan”).

7.4. Upgrades and downgrades. You may choose to upgrade or downgrade which particular Business Plan you are on at any time during a Month, provided you may only do so once a Month (other than where you obtain approval from support@what3words.com to do so twice). If you choose to upgrade your Business Plan to a tier allowing higher usage, your Fees payable will be calculated on a pro rata basis for the rest of that Month and you will be able to benefit from the increased usage amount (which will not be pro-rated for the rest of that Month) from the day that you upgrade. If you choose to downgrade your Business Plan to a tier of Business Plan allowing lower usage or to the Free Plan, the change to the lower usage amount and the corresponding reduction or disapplication of Fees payable will start to apply on the first day of the following Month.

7.5. Measurement of usage. what3words will endeavour to notify you of your usage once you have reached certain percentage thresholds of the convert-to-coordinates requests permitted by your Plan during the relevant Month. If your usage (in terms of convert-to-coordinates requests per Month) goes beyond that permitted by your Plan, what3words reserves the right to charge you for such additional usage. what3words’ measurement of your use of the API is final.

7.6. Fees payable. The fees payable for your use of the API are either as set out for each Plan here or (in respect of bespoke use cases) prices that are set out in writing by what3words (an email from what3words’ CEO or COO will suffice) (the “Fees”). what3words reserves the right to amend the Fees by giving you at least thirty (30) days’ prior written notice, with any amendment in Fees taking effect in Month following expiration of this notice period, such that you are entitled to terminate the Agreement in accordance with Clause 15.

7.7. Invoicing for Business Plans. what3words or its payment provider will issue an electronic invoice to you for Fees payable by you: (i) in advance in respect of usage at or below the maximum amount permitted by your Plan for the following Month; and (ii) in arrears in respect of any usage above the maximum amount permitted by your Plan for the previous Month if what3words has notified you that Fees are payable for this additional usage.

7.8. Payment. You shall pay all amounts set out in the invoice within thirty (30) days of the date of that invoice in the currency specified on the invoice. You are responsible for providing complete and accurate billing and contact information to us (or our third party payment provider) on or before acceptance of these Terms, and for notifying us (or our third party payment provider) of any changes to such information.

7.9. Taxes. You are responsible for all applicable taxes. All prices stated are exclusive of value added tax (if any) or any other locally applicable equivalent sales taxes, which is payable by the you at the rate and in the manner from time to time prescribed by law. If you are required by applicable laws and regulations to make any deduction or withholding, you shall pay to what3words such additional amount as is necessary to ensure that the net full amount received by what3words after the required deduction or withholding is equal to the amount that it would have received had no such deduction or withholding been made.

7.10. Late Payments. If you fail to make a payment due to what3words by the due date of payment, we reserve the right to charge you interest, calculated at the lower of: (i) a rate of one and half percent (1.5%) per month; and (ii) the maximum rate permitted by applicable law, calculated on a daily basis from the due date for payment up to and including the date of actual payment. what3words reserves the right to suspend your access to the API for any late payments.


8.1. You agree to keep any username, password, API key or other credentials (the “Credentials”) which you use to access the API secret and confidential at all times and you shall ensure that no third party shall access the API utilising your Credentials. Under no circumstances shall you display these Credentials on a public bulletin board, file transfer protocol site, internet site, chat room or file sharing site.

8.2. In the event that you suspect that any third party may be making use of your Credentials, you agree to immediately inform what3words by email at support@what3words.com of this fact and provide all reasonable assistance to what3words in relation to any subsequent investigation or other activities undertaken by what3words as a result.


9.1. We do not provide you with any Personal Data (as defined under the General Data Protection Regulation (EU) 2016/679) through your use of the API. When a call is made to our API via your API key, we will receive the following information: your API key, content of the API call (typically, the 3 Word Address searched), a timestamp and the IP address from which the call was made. what3words will process this data in line with our Privacy Policy. You agree to make the what3words Privacy Policy readily available to the users of Your Products.
