Paste-prompt for your agent:

Help me build against the Postify API. Read https://usepostify.com/llms.txt first — it indexes the guides and Markdown twins of every API page. Base URL: https://app.usepostify.com/v1, auth: Authorization: Bearer postify_live_… (I'll provide the key). Use Idempotency-Key on POST /v1/posts, honor Retry-After on 429, and note that delete/publish-now return 403 dangerous_ops_disabled until the workspace owner opts in.
