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

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.

Webhook Callbacks

Get notified when tasks complete — pass a callback_url when submitting:

result = sb.submit_task("web_browse", {
    "url": "https://example.com",
    "instruction": "Extract headlines"
}, callback_url="https://your-server.com/webhook")
# We POST {task_id, status, result} when the task completes

Agent Discovery

Your agent can discover SiliconBridge programmatically:

# Everything in one call
curl https://siliconbridge.xyz/api/discover

# Live platform status
curl https://siliconbridge.xyz/api/status

# Machine-readable
curl https://siliconbridge.xyz/.well-known/agents.json
curl https://siliconbridge.xyz/.well-known/llms.txt

Agent Identity Tiers

Agents earn tiers based on lifetime spend:

identity = sb.check_identity()  # GET /api/identity

• L402: Any paid endpoint auto-returns HTTP 402 with payment instructions when balance is low

Referral Program

Add referral_code to any task — both agents earn 25% lifetime recurring credits.

result = sb.submit_task("web_browse", {"url": "..."}, referral_code="your_code")
