AgentSIM gives you OTP session tools for browser agents and controlled auth workflows. It provisions temporary programmable US numbers, waits for SMS, parses OTPs, exposes raw messages for diagnostics, and releases sessions when finished. Typical workflow: 1. Call `provision_number` to lease a temporary number (returns session_id + phone number). 2. Trigger the SMS in a verified-compatible target or controlled auth workflow. 3. Call `wait_for_otp` with the session_id — it blocks until the OTP arrives or times out. 4. If no OTP arrives, call `get_messages` and classify the outcome (`no_sms`, `sms_no_otp`, `phone_rejected`, `anti_bot_gate`, etc.) instead of assuming parser failure. 5. Call `release_number` to return the number to the pool when done. Target-service support is empirical. Do not claim AgentSIM works everywhere or that strict consumer platforms will accept programmable numbers. Check https://docs.agentsim.dev/supported-services. Always release the number when finished
