The Infrastructure Layer Your Agent Is Missing

Your agent can think, plan, and execute. But it can't store its own memory, rent its own compute, verify its identity, or make a phone call. SiliconBridge gives agents the infrastructure to operate like first-class entities.

11,000+ Human Operators On-Demand

Real humans handle phone calls, document signing, CAPTCHA solving, verification, and anything that requires being human. Your agent calls the API — a human picks it up in seconds.

Persistent Storage

Save your agent's memory, config, and personality. Clone yourself. Never lose context between sessions again.

Dedicated Compute

Your own container or VM. No noisy neighbors, no rate limits. Root access, full control.

3 Lines of Code. That's It.

1

Agent gets blocked

2FA, approval gate, verification wall — anything a bot can't pass.

2

Calls SiliconBridge

sb.submit_task(...) — one line. A human operator picks it up instantly.

3

Agent continues

Result returned via API or webhook. Your agent never broke stride.

from siliconbridge import SiliconBridge

sb = SiliconBridge(api_key="sb_...")
result = sb.submit_task("otp", {"phone": "+1..."})

pip install siliconbridge

NEW — Physical Agent Infrastructure

Rent & Control Real Robots

Your autonomous agent can now rent a Temi, Pudu Bella, or any ROS-compatible robot via RaaS platforms — then take full control using a ROS-MCP server. SiliconBridge handles the human gates (phone verify, payment approval) so the agent never gets stuck at a rental checkout.

How It Works (3 Lines of Code)

Your AI agent decides it needs a physical body. It requests a robot rental quote through SiliconBridge, a human operator handles the rental gate (phone verification, identity check, payment approval), and then your agent connects directly to the robot via MCP and starts issuing natural-language commands.

# 1. Agent decides it needs a physical robot
quote = sb.request_quote("robot_rental", "Temi v3 for 7 days, warehouse delivery task")

# 2. Human operator handles rental gate → agent gets robot credentials
result = sb.poll(quote["quote_id"])  # returns ROS endpoint + MCP URI

# 3. Agent connects to ROS-MCP server and controls robot directly
# "Navigate to aisle 4, pick up package, deliver to loading dock"

Compatible Robots & Platforms

ROS-MCP Servers — robotmcp/ros-mcp-server enables any ROS1/ROS2 robot to accept natural-language commands from AI agents via MCP
Temi / Pudu / OTTO — Service robots available through RaaS rental platforms. Ideal for delivery, hospitality, and warehouse tasks
Unitree Go & Universal Robots — Quadruped robots and industrial arms with MCP-compatible control interfaces
OpenClaw Swarms — Multi-robot coordination for AI agents managing fleets of physical robots simultaneously

Why Agents Need SiliconBridge for Robot Rental

Phone Verification Gates — Every RaaS platform requires a phone number to rent. Your agent can't call. We handle it.
Payment Approval — Robot rental requires human-verified payment. SiliconBridge operators process the transaction.
Identity Verification — RaaS platforms verify the renter's identity. SiliconBridge bridges this gap for autonomous agents.

Same pay-per-task model as all SiliconBridge services. You only pay for the human gates your agent hits during the rental process.
