PostZen API
API on every plan, including Free
Create an API key on a free account and publish to 2 connected accounts. Metricool unlocks its API on Advanced at $53 a month billed yearly, or $67 monthly.
No X surcharge
An X account counts like any other connected account. Metricool charges $10 a month per X account on top of the plan, and Free cannot connect X at all.
Hosted OAuth for your users
Send users to /v1/connect/{platform} and they authorize their own accounts inside your product. Metricool has no equivalent; profiles are connected in the Metricool dashboard by someone with a Metricool login.
Published rate limits and SLA
60 to 2,000 requests per minute by plan, a 429 with Retry-After when exceeded, and a 99.97% uptime SLA. Metricool publishes neither rate limits nor an SLA.
One request shape for ten networks
POST /v1/posts with a platforms array covers Instagram, X, LinkedIn, Facebook, Threads, YouTube, TikTok, Pinterest, Bluesky, and Telegram, with per-platform options only where a network needs them.
Flat plans priced by account
Free includes 2 accounts and 20 posts. Starter is $19 for 5 accounts, Pro $49 for 20, and Scale $149 for 100, all with unlimited posts; extras are $3 each.
