SiliconBridge — Human-in-the-Loop API for AI Agents

![PyPI](https://pypi.org/project/siliconbridge/) ![npm](https://www.npmjs.com/package/siliconbridge) ![License: MIT](https://opensource.org/licenses/MIT)

When your AI agent needs a phone call made, can't pass 2FA, or needs someone to browse a URL — SiliconBridge routes it to a real human operator who solves it in <60 seconds via API.

Multiple services from $1. No subscriptions. MCP-native. Wallet/Nostr signup. Crypto payments.

Why SiliconBridge?

Every agent framework talks about human-in-the-loop, but they all punt on the hard part: where do the humans come from?

HumanLayer gives you approval UIs — but you still need to approve it yourself
gotoHuman gives you review dashboards — but you review the content yourself
SiliconBridge gives you actual human strangers who make phone calls, verify identities, browse websites, and handle real-world tasks

Your agent submits a task. A human solves it. Your agent gets the result. That's it.
