01What is SandBase?

SandBase is an agent infrastructure platform for developers. With one API key, it provides unified access to more than 2,000 models and data APIs, an E2B-compatible sandbox runtime, and compatibility with the OpenAI Agents API. Developers can let agents access real-world data, run code, and process files; package familiar workflows into Personal Agents; embed them in their own products or use them through CLI and MCP tools; and pay based on usage.

02Key Features of SandBase

Follow on WeChat and reply “开源” to join the AI open-source project community
Model access: Compatible with the OpenAI Agents API standard, allowing developers to use the familiar OpenAI SDK to create agents, establish sessions, and run tasks.
Data APIs: Covers real-world data such as X, YouTube, web search, and company information. Some APIs provide 100 free calls per day.
Sandbox execution: Provides an E2B-compatible runtime where agents can run code, process files, and return results. Existing E2B code can be migrated at low cost.
Tool integration: Supports SKILL.md, CLI, and local MCP bridging, enabling direct integration with existing AI tools such as Claude Code, Codex, and Cursor.
Skill templates: Includes reusable Skills for Twitter intelligence, YouTube transcription, SEO analysis, company research, and more to help agents complete practical work.

03How to Use SandBase

Register an account: Visit the SandBase website https://www.sandbase.ai/ to register, then open the Console to obtain a SandBase API Key.
Quick integration: In AI tools such as Claude Code, Codex, and Cursor, paste the instruction set up https://www.sandbase.ai/SKILL.md so the AI assistant can automatically configure the environment.
Select a model: Use the OpenAI-compatible endpoint api.sandbase.ai/v1 and the OpenAI SDK to specify the required model, create an agent, and configure task instructions.
Connect data: Use the same API key to call data APIs for X, YouTube, web search, and more. Review capability details and pricing before making calls.
Run tasks: After creating an agent session, submit tasks. The agent will run code in the sandbox, organize information, and generate result files.
Review results: Manually verify that the original links are valid and that the output meets the filtering criteria. Integrate the workflow into your own product after confirming its reliability.

04Core Advantages of SandBase

Unified access: One API key connects models, data APIs, and the sandbox, eliminating repetitive engineering for multi-platform authentication and account management.
Protocol compatibility: Compatible with the OpenAI Agents API and E2B SDK, allowing developers to reuse existing coding patterns with low migration costs.
Ecosystem integration: Directly embeds into mainstream AI tools such as Claude Code, Codex, and Cursor through SKILL.md, CLI, and MCP bridging, using agents as an acquisition channel.
Real-world data: Connects to real-world data APIs such as X, YouTube, and web search, enabling agents to complete tasks with practical outputs.
Broad coverage: According to official figures, connects to more than 2,000 models and APIs across more than 100 platforms, meeting diverse selection needs.

06SandBase Use Cases

Expert-level training data production: Organizes industry experts for frontier model companies to produce high-barrier SFT data in batches, covering fields with “expert-level cognitive density” such as finance, law, medicine, and STEM.
RL environments and “anti-pattern” data: Builds reinforcement learning environments and “anti-pattern” training datasets for models, helping them improve reasoning and error correction through multiple rounds of trial and error. It has also open-sourced datasets and training outputs such as Dynasor and ProRL.
Benchmark evaluation and “building the exam room”: Provides expert-level benchmark evaluation services that simulate real examination environments to test models’ actual performance on highly challenging professional tasks. Evaluation results are provided as a reference for model laboratories.
Advancing model capabilities in vertical industries: Targets specialized professional scenarios beyond programming, producing training tasks that reproduce real workflows so models can perform reliably on long-chain professional tasks.
