# Write a social post (+ image)

`POST /v1/ai/social-post`

## Request

- Base URL: `https://apihub.co.il`
- URL: `https://apihub.co.il/v1/ai/social-post`
- Auth: HTTP bearer

A ready post per network (length, hashtags and style fitted to each: Instagram, Facebook, LinkedIn, X, TikTok…) in your language and tone — and, optionally, the post image. Publish it with POST /v1/social/publish. An Instagram post keeps at most 5 hashtags (Instagram's limit) and comes with `check`: the ~125 characters the feed shows before "… more" and what to fix.

**Billing:** By the tokens / images / seconds the model reports — see GET /v1/ai/models for prices · **Rate limit:** 30/min
