Building on the Protocol: The GX Coin API Suite

The GX Coin Protocol is more than a new currency; it is a new economic operating system. While the protocol's core, its immutable chaincode and monetary policy provides the foundational stability, its soul lies in the vibrant ecosystem of applications and services built upon it.

Our Application Programming Interfaces (APIs) are the gateways to this new world. They are the tools we provide to our chartered partners and institutional stewards, enabling them to build the foundational industries of this global economy. We operate on a clear "protocol vs. application" model: the GX Coin Foundation maintains the core public utility, and our partners use our APIs to build the innovative, competitive services that will define the future of commerce and finance.

The information presented here provides a comprehensive overview of the API suites available and the process for gaining access to them.

Access to our APIs is structured in tiers, reflecting the role and commitment of each participant in the ecosystem.

• Public API (Coming Soon): A read-only API that will allow the general public to access public blockchain data, such as transaction histories and network statistics, fostering transparency.
• Chartered Partner API: A robust, full-featured suite of APIs available exclusively to institutions that have acquired a Global, Regional, or National charter. This is the primary toolkit for building commercial services.
• Validator API: The most privileged tier of access, granted only to approved Validator institutions. This suite includes advanced governance functions and unparalleled access to real-time economic data.

Gaining access to the Partner API suite is an integrated part of becoming a chartered institution.

1. Charter Acquisition: The institution first applies for and acquires a charter for a specific domain (e.g., Capital Markets, Commerce & Trade) and geography, which includes the payment of the charter license fee.
2. Execution of Agreements: The partner executes the legal Charter Agreement and a specific API License Agreement, which governs the terms of use, security requirements, and acceptable use policies.
3. Technical Onboarding & Key Provisioning: Our dedicated partner engineering team works directly with your technical team to provision secure API keys and credentials. We support industry-best standards for authentication and access control.
4. Sandbox Environment Access: Partners are given access to a robust, full-featured sandbox environment. This allows for rigorous development, testing, and integration of your applications without interacting with the live network.
5. Production Go-Live: Once your application has passed all security and integration tests, you are cleared for production access, and your service can go live on the main GX Coin Protocol network.

This suite is the engine for innovation, providing all the necessary tools to build sophisticated financial and commercial applications.

This is the foundational layer for interacting with the blockchain.

• Accounts API: Programmatically create and manage user and business accounts on behalf of your customers, interacting with our core identity layer.
• Transactions API: Securely initiate, sign, and broadcast transactions. Query transaction status, retrieve details, and build reliable payment flows.
• Ledger API: Read-only access to the public ledger. Query block data, historical transactions, and account balances for auditing and data analysis purposes.

This is our unique, privacy-preserving trust engine. As the Foundation maintains control of the core Identity Graph, this API allows partners to verify user attributes without accessing raw personal data.

• How it Works: The API responds to specific, permissioned queries with a cryptographic "yes" or "no" (or a numerical value).
• Example Queries:
  • verify_user_attribute(user_id, 'country', 'Kenya') -> returns TRUE/FALSE
  • verify_user_attribute(user_id, 'age', '>=18') -> returns TRUE/FALSE
• Value: This allows you to meet compliance and risk-management requirements (e.g., for lending) without the liability of storing sensitive user data, a core principle of "privacy by design."

• LoanPool API: Build applications that allow businesses and individuals to apply for capital from the protocol's central zero-interest loan pool. Manage the application lifecycle, check statuses, and handle repayments.
• SmartCredit API: A powerful toolkit for creating and managing peer-to-peer lending and profit-sharing smart contracts. This allows you to build sophisticated investment platforms, venture capital vehicles, and other credit products on the protocol.

• Payment Gateway API: A "Stripe-like" suite of tools for merchants. Easily integrate GX Coin payments into online checkouts, create invoices, manage subscriptions, and process refunds.
• Marketplace API: Tools specifically designed for building "d-Commerce" platforms. Manage product listings, facilitate multi-party transactions, and utilize smart-contract-based escrow services for high-value goods.

This privileged suite is reserved for our institutional stewards and is focused on governance and unique research capabilities.

• Economic Insights API: The crown jewel of our data offerings. This provides real-time, aggregated, and anonymized data streams on the health of the entire economy.
  • Key Metrics: Capital velocity, transaction volume by sector, Gini coefficient (wealth distribution), loan pool utilization rates, and cross-regional trade flows.
  • Value: This is an unprecedented source of primary data for economic research, modeling, and policy analysis.
• Governance API: Programmatic access to participate in the Validator Governance Council. Submit proposals, vote on protocol upgrades, and manage the admission of new validators.

All our partners receive access to a comprehensive developer portal with detailed documentation, code samples, and dedicated engineering support to ensure a smooth and successful integration.

We invite the world's builders to join us. With these tools, you will not just be creating an app; you will be architecting the future of finance.
