6.2. Access Restrictions.

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

(b) No hiding identity . You must make it clear when requesting an API key the entity on behalf of which you are making the request. If what3words suspects that multiple API keys have been requested on behalf of the same entity in order to circumvent payment obligations, what3words shall be permitted to take appropriate actions including, but not limited to, rejecting requests for API keys, suspending access to the API and charging for usage of the API in accordance with clause 7.9 of this Agreement. You will not hide from what3words the identity of Your Product.

You shall be responsible for and monitor their compliance with this Agreement 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 or any what3words Data 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 of Your Products to reverse-engineer coordinates from a 3 Word Address.

(b) Display of 3 Word Addresses . You may display 3 Word Addresses in Your Products, but you must not display, or otherwise share with any third party, any 3 Word Address alongside its corresponding coordinates.

(c) 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.

(d) Converting 3 Word Addresses . If you need the coordinates for a 3 Word Address, you shall always make a call to our API. If you are storing a 3 Word Address with its coordinates (see Clause 6.3(e) below) and this means you already have the coordinates of a particular 3 Word Address, you shall still make an API Request to convert that 3 Word Address to coordinates. You must not store, pre-fetch, cache, index, copy, re-utilise, extract, incorporate or utilise any what3words Data or the API (or any part thereof) in any way that means you are effectively circumventing: (i) you or any third party from making an API Request to convert a 3 Word Address to coordinates; or (ii) any third party from using our API or any of our other products.

If you have converted coordinates to 3 Word Addresses, you may store up to 100,000,000 (one hundred million) 3 Word Addresses with their corresponding coordinates, if this is strictly necessary for your product or use case.

(iii) Storage of 3 Word Addresses with Coordinates: converting 3 Word Addresses to coordinates . If you have converted 3 Word Addresses to coordinates, you may only store 3 Word Addresses with their corresponding coordinates if: (a) it is for the sole purpose of improving the performance of Your Product; (b) this storage is temporary (up to a maximum of 30 calendar days) for each 3 Word Address with coordinates; and (c) any storage is limited to the amount of data which is strictly required to achieve this purpose. Otherwise, you shall not store 3 Word Addresses with their corresponding coordinates.

(iv) Storage of coordinates derived from a 3 Word Address. You may not store the coordinates derived from a 3 Word Address (derived using any of our products) if this circumvents the need for you or a third party to make a call to our API. In particular, this includes the storage of coordinates derived from a 3 Word Address next to a traditional street address or other location information.

(f) Rules on data storage. You must ensure that any storage of what3words Data is secure and does not and cannot enable you or a third party to use that data outside of Your Product, or to re-utilise or extract that data.

(h) 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.

what3words may terminate this Agreement upon written notice to you if what3words (acting reasonably) determines or suspects that you have breached any of the restrictions in this Clause 6.3(i).

(j) 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.

(n) Integration Cooperation . If requested by what3words, you agree to cooperate with what3words to resolve any issues with the integration of the API into Your Product and to make any adjustments what3words deems necessary to ensure the end user experience is in line with other what3words integrations.

6.4. Facilitation Period for our licensees using the API for delivery purposes.
