Our API is open because we want people to build on it. What isn't ok is copying our original piece designs, board graphics, icons, UI or other IP, and using them in a product without permission. In January, we found Chessiro was doing exactly this, so we reached out to request they stop. They ignored us for three months. We followed up again and blocked their API access. Within about 24 hours, they made the changes we'd been asking about for months. Not everything is fixed, but we've restored their access and will share a list of remaining items that still need to be addressed. We opened the API as a show of good faith, and hope they'll resolve the rest quickly. We're interested to see what they build and offer the chess community.
