+
+## Abstract
+
+In the current Duniter server, the old BMA api is deprecated and will be removed.
+The WS2P API is dedicated for the inter-node communication.
+
+We propose here a new API Module dedicated to client software.
+It should deliver efficiently all information needed without slowing down the Duniter node.
+
+## API standard
+
+It is important that we use an already known standard to avoid difficulty in contribution. And to get all the evolution and ideas coming from the community supporting the standard.
+
+The proposed standard is [GraphQL](http://graphql.org/). Created by Facebook, it is used by many companies around the world.

+
+## Librairies
+
+GraphQl use queries that need to be parsed by the server implementation. So the use of a library avoid to write ourselves the base code.

+## GraphQL Verification API
+
+This is the name proposed for this API implementation.
+
+Why ?
+
+- We use **GraphQL**
+- We make data changes **Verification**
+- This is an **API** ;-)
+
+## Merckle Tree verification system
+
+To speed up the queries, we need to use intensively the Merckle Tree comparison system.
