SandBase
Unified model/data APIs, managed agents, and E2B-compatible sandboxes
SandBase combines model APIs, data services and hosted agent/session resources under one organization, API key and balance. Its documentation covers OpenAI-compatible Chat Completions and agent/session endpoints; sandbox access uses the E2B JavaScript and Python SDKs with SandBase connection settings. These compatibility claims were not independently tested end to end. The @sandbaseai/cli package provides shell commands and a local MCP bridge to https://api.sandbase.ai/v1/mcp. The CLI is Apache-2.0 licensed and requires Node.js 20 or newer; that license does not cover the hosted platform. Pricing checked on November 9, 2026 lists 100 eligible data API calls per organization per day, resetting at 00:00 UTC. Models and additional API usage are metered at the selected capability’s price, without a required monthly subscription. Sandbox access is currently free with possible fair-use caps and future pricing changes. Verification covered the public OpenAPI 3.1.0 specification with 69 paths, npm artifact integrity and isolated CLI 0.3.8 version/help commands. Unauthenticated model/account reads, MCP initialization and sandbox-template listing returned HTTP 401. Authenticated tool discovery, model calls, agent execution, sandbox creation and free-credit allocation were not exercised.

In 4agent’s task model, the product maps to Web extraction, Code execution, Workflow automation. That makes it a candidate for these tasks: Research the web, Manage memory and knowledge, Build and deploy software, Communicate with users.
Integration checklist
- Access: Confirm the api key authentication flow, credential scope, rotation process, and whether calls can be attributed to a user or service identity.
- Client support: Official or documented clients are listed for typescript, python.
- Automation: OpenAPI: listed as available; MCP: listed as available; CLI: listed as available. Confirm each requirement in the provider's current documentation.
- Operations: Test rate limits, timeouts, retry safety, error payloads, logs, data retention, and the current free-tier and paid pricing model with production-like volume.
