OpenADA Accessibility and Language API

Built 100% for the OpenAI Codex contest

Free accessibility infrastructure for every public service.

Federal web-accessibility compliance dates have been extended, not erased. OpenADA gives governments and small organizations a free way to scan, prioritize, and track improvements while expensive enterprise tooling remains out of reach.
