ITSA Releases Tokenbase API for Members And Updates ITIN Application Form

August 20, 2021 — The International Token Standardization Association (ITSA) has released the first version of its Tokenbase API. Active ITSA Members receive complimentary access to the API as part of their memberships. The API allows for the secure and instant assignment of new ITINs to freshly minted tokens and enables full ITIN integration for existing Tokens. This is an important feature for token issuers (especially in the area of STOs) as well as cryptocurrency exchanges and secondary markets. In addition, the ITIN application form has been updated and now also supports instant ITIN assignment. You can access the form here.

The ITIN Application Form

  1. Enter your contact details.
  2. Enter basic information about the token (Figure 1).
  3. Enter issuer information if available.
  4. Enter any social media channels used by the project.

Once you have made it through these steps, your ITIN will be assigned instantly. You will then be redirected to the new Tokenbase listing of your token. Should any problems arise, we will be sure to get in touch with you as soon as we can.

Tokenbase API for active members

The API can fulfill a number of requests, including providing full data on any listed token, returning only ITIN or ITC information, as well as searching the entire Tokenbase for tokens according to preselected filters. For example, through the API you can search and filter tokens according to ITC classifications. Additionally, the /create-itin call allows for instant ITIN assignments. While this function is made for STO / ICO issuance platforms to integrate ITINs in their issuance process, the search functions are more aimed towards data providers and exchanges. With the ITIN and ITC, they can create more order in their ecosystems and add an extra layer of transparency.

You can access the API documentation here. If you would like to use the API, please get in touch with to discuss membership options. Figure 2 shows an example of a successful /create-itin call.

From this, we can decipher that the ITIN of the new token is “BM4MGCP45”, as well as see that it is running on Ethereum (ledger=115). Depending on the information provided by the issuer of the request, we could also see social media URLs, ITC classifications, and more.

The International Token Identification Number

In short: ITIN is a 9-digit technical identifier for both fungible and non-fungible DLT based cryptographic tokens. It is both unique and fork-resilient and allows for the connecting and matching of other media and data to the token. Recently, there have been more and more calls for a unique identifier for tokens. Most notably, the ECB has specifically mentioned the ITIN in their recent paper on the use of DLT in post-trade processes.

  • The International Token Identification Number (ITIN) is a 9-digit alphanumeric technical identifier for both fungible and non-fungible DLT-based tokens. Thanks to its underlying Uniform Token Locator (UTL), ITIN presents a unique and fork-resilient identification of tokens. The ITIN also allows for the connecting and matching of other media and data to the token, such as legal contracts or price data, and increases safety and operational transparency when handling these tokens.
  • The International Token Classification (ITC) is a multi-dimensional, expandable framework for the classification of tokens. Current dimensions include technological, economic, legal, and regulatory dimensions with multiple sub-dimensions. By mid-2021, there will be at least two new dimensions added, including a tax dimension. So far, our classification framework has been applied to 99% of the token market according to market capitalization of classified tokens.
  • ITSA’s Tokenbase currently holds data on over 4000 tokens. Tokenbase is a holistic database for the analysis of tokens and combines our identification and classification data with market and blockchain data from external providers. Third-party data of several partners is already integrated, and API access is also in development.
