SandBase is a developer platform that gives agents and apps one API key for many AI models, data APIs and sandboxed code environments. Listings say it connects to more than 2,000 models and external data APIs, with an OpenAI-compatible endpoint and E2B-compatible sandboxes.

A tool listing says it provides an MCP gateway so assistants such as Claude Code can search, inspect and call models, media generators, web scrapers and social data feeds through one interface. The vendor describes reusable skills for tasks such as research and transcripts, and agents that can run code in a sandbox and produce files.

A Chinese review site says billing is pay per use, with a bonus on the first top-up. Exact rates were not confirmed, so check the official pricing page before building on it. This page is a summary based on public listings and the vendor’s own description, dated 2026-11-13. It was not tested hands-on, and details may have changed.
