This Valentine's Day, the Symbl.ai company is hosting a fun and easy API challenge for participants of all technical backgrounds and levels. The challenge involves taking a verse from a favorite love song and generating its sentiment using either Node.js or Postman within 5 minutes. Participants must tweet a screenshot of their results to @symbldotai or post on LinkedIn, tagging Symbl.ai, with the hashtags #BuildWithSymbl #SymblChallenge by March 14th to qualify for a chance to win a limited edition Valentine's Day-themed POP Funko figure. The challenge aims to help improve Symbl.ai's APIs and encourage participants to provide feedback.
