Hack-a-Sprint 2026 — Pre-event instructions
Everything you need to do before April 13 so you can hit the ground running on event day.
The Challenge
Build an AI agent using the Inkbox SDK that improves your own productivity or efficiency. Solo competition, 50 builders, 2.5 hours to ship.
Your agent should use at least one Inkbox capability (email, phone, or vault) and solve a real problem in your day-to-day workflow.
What is Inkbox?
Inkbox gives AI agents their email, phone, and secure vault.
Identities
Persistent, named agents with their own email address and phone number.
Send and receive emails, manage threads, search messages, attachments, and webhooks.
Phone
Outbound and inbound calls with real-time audio, built-in STT/TTS, and transcripts.
Vault
Zero-knowledge encrypted credential storage with TOTP support for your agents.
Get set up before the event
Do these steps ahead of time so you can start building immediately at 4:30 PM.
- Get an API key — sign up at inkbox.ai/console and create an API key from the dashboard.
- Install the SDK
pip install inkbox
npm install @inkbox/sdk
- Create an identity and send a test email
from inkbox import Inkbox with Inkbox(api_key="ApiKey_...") as inkbox: identity = inkbox.create_identity("my-agent") identity.send_email( to=["you@example.com"], subject="Hello from my agent", body_text="It works!", ) - Explore the docs — inkbox.ai/docs covers identities, email, phone, vault, and webhooks with full examples. The SDK is open-source at github.com/inkbox-ai/inkbox.
Ideas to get you thinking
You are not limited to these — build whatever makes you more productive.

- •An agent that does LinkedIn outreach for you — See it in action
- •An agent that manages your calendar and schedules meetings over email
- •An agent that does social media management, posting and replying on its own — See it in action
- •An agent that looks for job postings and applies via email follow-ups
