  "account": "The article explains how AI agents can read email verification codes without using regular expressions. The issue with regex is that it fails to distinguish between actual verification codes and other numbers commonly found in emails, such as order numbers, dates, and phone numbers. To overcome this, Agentboxd offers a solution where every inbound email is checked for a code or link the moment it is stored, before the agent requests it. This process involves three steps: noting the time, triggering the email, and waiting. Agentboxd waits for a verification email within 60 seconds and returns the newest code or link, eliminating the need for polling loops or sleep. The extraction process prioritizes precision, as a wrong code can be worse than none. Codes are normalized to a canonical value, and the system rejects imposters like numbers glued to other numbers, prices, and years unless a strong keyword is present. The AI classifier further confirms if the email is a login, one-time-code, or confirm-your-email message, with a confidence score of 0.95 for a clear yes and 0.2 for a clear no. This approach ensures reliable and accurate verification code extraction, even in complex email scenarios.",
  "summary": "Sign-up forms stop agents with “we sent you a code”. The obvious fix, a six-digit regex over the inbox, works in a demo and breaks on real mail. Here is why, and the one call that replaces it. TL;DR Give the agent its own inbox, note the time, trigger the email, then call GET /v1/inboxes/:id/verification (SDK waitForVerification , MCP get_verification_code ). It waits up to 60 seconds and returns…",
