API Hackday PDX brings developers together for an all-day coding fest focused on building apps and mashups with APIs. Developers of all experience levels can share ideas, collaborate on existing projects, start new ventures, and find out about great tools and new APIs to play with.

Free admission: Lunch, Dinner and post-hack beer included.

Hackers will also hear from some of the country's top API-focused companies on tips, tricks, and tools for building the next big app. At the end of the day, teams and/or individuals get a chance to present their work to a panel of judges and win kickass prizes.
