KeyFlow Architecture

Keyflow allows users to convert API credits from multiple providers to tokens, redistributing the value of the credits to the users. The architecture is designed to be modular, allowing for easy integration of new providers.

Each provider has its own smart contract deployed on BASE that converts API credits to tokens. Tokens are then listed on the marketplace, where users can buy and sell them. The marketplace is an application built on BASE, allowing for peer-to-peer trading of API credits.

Token Example

Keyflow MistralAI chat wrapper

Owning API credits with KeyFlow allows you to use the API of the associated provider. In this example, we use the Mistral AI chat wrapper. When making a request in the chat-demo, the request is signed with user's wallet and verified on the backend. Backend verifies the signature, checks remaining credits and makes a request to the provider's API on behalf of the user.

Key points:

• Credits remaining credits are automatically updated when new requests are made.
• Ownership verification happens via SIWE protocol.
• Demo's API is integrated with Mistral AI

Keyflow Marketplace

The marketplace is an application built on BASE, allowing for peer-to-peer trading of API credits.

Users can explore market for available credits by API providers and purchase them. Track their owned credits and list them for sale.

Key points:

• Providers can set a custom commission for each resell. Making second-hand market economically sustainable for them, as each resell increases price per credit.
• Credits are grouped by API provider, making it easier to compare and purchase.
• Listing and delisting of credits is instant.
