About the challenge

CALL-E is a developer-first platform for building AI agents that make real phone calls and get real-world tasks done. Instead of stopping at text, your agents can plan a call, dial out, hold a natural conversation, adapt in real time, and return structured results you can act on — all through CALL-E's SDK, API, and MCP. In other words: your agents can finally pick up the phone (and actually get something done while they're on the line). ☎️

In CALL-E: Your Code Is Calling, you'll put that to work. Build and deploy a functional application that uses CALL-E to solve a real business or project problem — customer outreach, appointment scheduling, lead qualification, service coordination, workflow automation, or something no one's tried yet. Whether you're an AI engineer, agent builder, or technical founder, this is your chance to push a brand-new platform in directions its makers haven't imagined, share feedback that shapes the roadmap, and compete for a share of $10,000 in prizes.
