AgentSIM — Real phone numbers for AI agents

# AgentSIM > Phone number provisioning API for AI agents. Provision real SIM-backed numbers, receive SMS, and extract OTPs — fully autonomous. No VoIP, no CAPTCHA, no human assumptions. Three API calls, ~3.5 seconds end to end. ## What It Does AgentSIM lets AI agents complete phone-based OTP verification without human involvement. It provisions real carrier-routed mobile numbers (line_type: mobile), receives incoming SMS, and returns structured parsed OTP codes. One session = one provision, one OTP, one release. $0.99/session. 10 free sessions/month. The core problem it solves: Twilio, Vonage, Plivo, and all cloud phone APIs return line_type: VoIP on carrier lookup. Services like Stripe, Google, WhatsApp, and banks block VoIP numbers. AgentSIM uses real SIM infrastructure so carrier lookup returns line_type: mobile — accepted everywhere. ## Quick Start ```bash pip install agentsim # or npm install @agentsim/sdk ``` ```python from agentsim import AgentSIM agentsim = AgentSIM(api_key="...") number = await agentsim.provision({"country": "US"}) otp = await number.wait_for_otp(timeout=30_000) # otp.code → "847291" # otp.service → "stripe" ``` ## Product - [Features](https://agentsim.dev/#features): Real SIM numbers, OTP parsing, per-agent scoping, MCP-native, webhook + polling - [How It Works](https://agentsim.dev/#how-it-works): Provision → Enter → Receive OTP.
