Clocked Build Challenge: Online AI Hackathon

A free, three-week online hackathon. Build a new working app that meaningfully uses at least one Clocked endpoint. Clocked is an LLM API that decides, extracts and fills structured outputs, and it also covers PII protection, prompt-injection detection, script inspection, grounding verification, document comparison and reranking.

$2,000 in cash across five awards: Best Overall App ($600), Best Use of Decide/Extract/Fill ($400), Best Use of Protect/Guard/Inspect ($400), Best Use of Verify/Compare/Rerank ($400), and People's Choice ($200, voted on LinkedIn).

Every participant can get 20,000 free API credits: 4,000 on a free Clocked account plus 16,000 with the code CLOCKEDHACKATHON. Solo builders and teams of any size, any language or stack. A demo and a public repo are required. Entries close November 10, 2026 at 11:59 PM Eastern Time; winners are announced November 18. 18+; location and other restrictions apply.
