6

[GENERAL] Please indicate if your proposal has been auto-translated into English from another language

No

[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

Create a comprehensive, free API platform for price, swaps, and token data on Cardano, enabling developers to build trading bots, analytics tools, and applications to boost ecosystem growth.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

Yes

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

We depend on existing decentralized exchanges (DEXs) and blockchain data providers for real-time price, swaps, and token data. Integration with these platforms is essential to aggregate accurate and comprehensive data for the API services.

[GENERAL] Will your project’s output/s be fully open source?

Yes

[GENERAL] Please provide here more information on the open source status of your project outputs

While we utilize open-source technologies and contribute improvements back to the community, the core API platform will remain proprietary to maintain service reliability and security. However, we will offer free access to the APIs for developers if funded.

[METADATA] Horizons

Developer Tools

[SOLUTION] Please describe your proposed solution

We propose to develop a comprehensive API platform offering real-time price, swaps, and token data for the Cardano ecosystem, similar to Jupiter Metropolis API. This platform will provide developers with essential tools to build custom trading bots, analytics applications, and other services that require accurate market data and trading apis. By offering these APIs for free (if funded), we aim to lower the barrier to entry for developers and stimulate innovation within the Cardano community.

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

Ecosystem Growth: Providing free access to comprehensive APIs will encourage developers to build new applications, leading to increased activity and growth within the Cardano ecosystem.

Innovation Enablement: Developers can create custom trading bots, analytics tools, and other innovative services, enhancing the functionality available to users.

Increased Trading Volume: Enhanced tools and applications can lead to higher trading volumes, benefiting liquidity providers and traders alike.

Community Empowerment: By lowering development costs, we empower a broader range of developers, including independent and small teams, to contribute to the ecosystem.

Competitive Edge: Offering robust APIs can attract projects from other ecosystems to build on Cardano, improving its competitive position in the DeFi space.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Our team has extensive experience in developing DeFi applications, exemplified by our work on DexHunter, Cardano's leading DEX aggregator. We possess the technical expertise to build scalable and reliable API services. Currently, DexHunter processed more than half of the entire Cardano trading volumes.
