Requirements by network
Run it from code
The same check is a free API: send the file's metadata, never the file. No key, JSON by default, Markdown with Accept: text/markdown.
curl -s "https://usepostify.com/api/tools/validate-media?type=video/mp4&bytes=48000000&width=1080&height=1920&duration=42"
Then schedule it in Postify
Once the file fits, Postify publishes it to every network from one composer, each with its own caption. There is a free plan with no credit card required.
