Verdicts

Before you call either
OneUp API + MCP
- Call listcategory, then listcategoryaccount, then schedule. Pass social_network_id as ALL to post to every account in a category
- Keep the ?apiKey= URLs out of logs and shared configs, and regenerate the key on the API Access page if one leaks
- Set requireApproval or isDraftPost true when a person should review before anything goes out
- Page through lists with start, 50 posts at a time
- Give dates as YYYY-MM-DD HH:MM with no timezone field, so confirm the account timezone first
Post Bridge API + MCP
- Call list_social_accounts first, upload media, then create_post. Omit scheduled_at to publish at once
- Check list_post_results before republishing a failed Instagram post, since Meta 500s often publish anyway
- Set is_draft true when a person should approve the post
- Put links for X in a reply, because captions sent to X lose their URLs
- Stay under 10 requests a second per key, and trigger sync_analytics no more than once every 30 minutes per account
