Subscribe to a domain: get a signed webhook (X-Desvela-Signature, HMAC-SHA256) when what it publishes for AI agents changes — ai-catalog.json entries added/changed/gone, llms.txt or agents.md edited or removed, robots.txt AI-bot directives changed. Checked weekly against the Desvela ARD index. Returns a manage_token (GET/DELETE https://registry.desvela.dev/watch/{id}) and the signing secret — store both.
