Overview

Time: 28/1/2026~15/2/2026

Ninja API Forge is a developer-focused contest centered on API creation rather than application building.

Participants are invited to design and implement their own APIs, powered by Injective’s on-chain data and trading infrastructure. The contest encourages developers to think in terms of abstraction, interface design, and reusability, contributing new infrastructure layers to the Injective ecosystem.

What You Build

You will build one custom API service designed for other developers to consume.

Your API should expose useful data or functionality derived from Injective, through clean and well-defined endpoints.

Suggested API Directions

1. Data Aggregation APIs

Simplify or restructure Injective data into developer-friendly formats.

Examples:

• Market or trading summaries

• Orderbook depth snapshots

• Trading activity feeds

• Price history endpoints

2. Computation or Derived Data APIs

Provide processed or calculated results instead of raw data.

Examples:

• Liquidity or volatility metrics

• Market health indicators

• Risk or exposure analysis

• Custom market signals

3. Developer Utility APIs

Improve the overall developer experience.

Examples:

• Unified or simplified query endpoints

• Cached or normalized data APIs

• Multi-market aggregation APIs

• Lightweight indexing or helper services

4. Special Track: Identity-Aware APIs（N1NJ4 Track）

This track focuses on APIs that understand, verify, or leverage developer identity using N1NJ4 as a primitive.

Technical Scope

• You may use Injective data sources internally

• You must expose your own API endpoints

• REST, GraphQL, or similar interfaces are acceptable

• Local or test deployment is sufficient

You do not need to:

• Deploy smart contracts

• Build a frontend

• Handle real funds

Submission Requirements

Step 1: Submit via Typeform

All projects must be submitted through the official Typeform:

👉 https://xsxo494365r.typeform.com/to/iiNKwjI8

You will be asked to provide:

• Project name

• GitHub repository link

• Short description of your API

• Any additional notes you would like the reviewers to know

Only submissions received through the Typeform will be considered for evaluation.

Step 2: Share Your Project on X (Twitter)

After submitting the Typeform, you must publish a public post on X introducing your API project.

Your post should:

• Briefly explain what your API does

• Include a link to your GitHub repository

• Tag the following accounts:

  • @injective

  • @NinjaLabsHQ

  • @NinjaLabsCN

• A public GitHub repository

• A README covering:

  • What the API does

  • Main endpoints and parameters

  • Injective data sources used

  • How to run the API locally

Evaluation Criteria

Submissions will be reviewed based on:

1. API Design Quality

2. Practical Developer Usefulness

3. Code Structure and Clarity

4. Reusability and Extensibility

UI and visual design are not part of the evaluation.

Rewards

Total Prize Pool: 350 USD

1. Main Prizes: Top 3 Selected Projects, 100 USD per project

• Selected based on overall API quality

• Focus on usability, clarity, and reusability

2. Special Prize: Best Developer API — 50 USD
