The The SingularityNET Marketplace is a decentralized application (DApp), which lists the available AI services and helps you to interact with those services through web interface abstracting all the complexity in invoking a service. It also processes payment for services (through MetaMask/General Wallet) and conduct service ratings. Whenever a transaction happens on Blockchain, an event is created. The marketplace monitors all those events. For example, if you publish a new organization, a new service, the marketplace receives an alert notification about published information in the Blockchain. The marketplace reads the organization metadata, the service metadata and the stores this into its database. This application efficiently displays all the details quickly without relying on the slow performance of the Blockchain The following image shows the contents from the marketplace.
The decentralized application (DApp) does the following:
Reads data from the on-chain Registry and pairs it with off-chain metadata. This allows for searching, filtering, and discovering AI services.
Integrates the SingularityNET curation service, and displays from the registry. Whenever an event comes from Blockchain, the details are stored in the local database, the review process is done on that data, and then when approved, the information is made available in the marketplace. Note: Displays those services that have been vetted, and owners who have experienced due diligence and signed legal agreements that protects user and data privacy.
Displays custom UI components for interactions with AI services. It enables you to quickly build the UI components and host the component on the platform, and also you can determine what inputs need to be chosen for service execution, and is the expected output, without understanding the complexity of knowing the gRPC protocol, the proto that is associated with the service and how to call the service and so on.
Integrates with Multi-Party Escrow, to allow consumers to pay for service usage; Allows consumers to rate about the utilized services Note: This rating services will be part of the SingularityNET’s Reputation System (currently under development). Currently, it is very difficult to rate services on Blockchain. Therefore all rating mechanism are performed off chain and managed in the market place. So you can share your opinion and reviews at marketplace.
Captures usage metrics at a consumer level.
Note: Although, the SingularityNET platform is open and decentralized, the Marketplace is the SingularityNET Foundation’s curated view. This allows the foundation to adhere to legal requirements of different legislative regions. Currently, the Marketplace and SingularityNET is in beta stage. For more information about the current status, refer to current status page for changes, or follow the git-repo
If you are a service author, for the service to be visible to others and listed on the marketplace you must:
All complexity of invoking a service is abstracted from the users. For example it becomes easy for the user to Input the values that need to be sent and view the computed expected result in the Output field, even without knowing the complexity of the gRPC calls/generating signatures for authorization to call a service.
Please note that the the Marketplace offers a free trial version, where registered users can access service(s) for a specified number of calls.
Once your freecalls are exhausted , you will need to pay for any new calls to the service. for this you need need a wallet, some ethers in your wallet , some AGI in your wallet
You can either pay through Metamask or through a General wallet(paypal)
Lets look at each of the wallet options in detail below
Important: Metamask is a plugin which is used by the SingularityNET platform. This extension, allows you to perform the following in the context of the marketplace:
As a first step you will need to Authorize the Dapp to connect to your metamask account
If you dont have money on Escrow account, you will be asked to Deposit into Escrow Now click on Deposit
You need to confirm every Blockchain transaction when using metamask as your mode of payment
Based on the number of calls you wish to invoke ,select the option and the channel will be funded accordingly
Once the funds are in the channel, you are all set to invoke the service !
Select the ‘General Wallet’ Option
If you are using General Wallet and you have sufficient funds , you will see the continue button
You can now continue to use the Service till you have sufficient funds before the expiry date of the channel
