The short version
Upload-Post is a developer-first social media API — one endpoint to upload videos, photos and text to a long list of networks, with SDKs and connectors for automation tools such as n8n, Make and Zapier.
SOSPosting is a cross-posting and growth tool: ten channels connect, and one upload becomes platform-native posts on each one that fits — up to seven at a time for a photo, five for a video — with the copy written per network, products published to Shopify and WordPress, and Google Ads reviewed alongside. Pricing is pay-as-you-go rather than a subscription.

| SOSPosting | Upload-Post | |
|---|---|---|
| Interface | REST API + dashboard + Telegram bot | API-first, with connectors |
| Authentication | Bearer API key | API key |
| Captions | AI per network, or your own text | You supply the text |

Where Upload-Post is strong
- A long list of supported networks behind one endpoint.
- Official SDKs and ready-made automation connectors.
- A free allowance that makes it easy to try from code.
Where SOSPosting is different
- An API and a product. The same account has a web dashboard, a Telegram bot and an inbox — the person who is not a developer can post and reply without your code.
- Captions are written for you. Send the media and a brief; each network gets its own caption, or pass your own text to skip the AI.
- Status and metrics read-back. `GET /api/v1/posts/:id` returns each delivery's state, link and counts, so you do not have to poll each network.
Frequently asked questions
Is there an alternative to the Upload-Post API?
Yes. SOSPosting exposes a REST API under /api/v1/ — create a post with one call, upload media through a presigned URL, and read back per-network status and metrics. It is priced per publish from a token pack rather than by monthly plan.
How do I get an API key?
Create an account and mint a key in the console under Settings → API access. Requests authenticate with an Authorization: Bearer header. The full reference is on the developers page.
Which should I choose for an automation?
If you need the widest network list and an off-the-shelf n8n or Make node, Upload-Post is built for that. If a non-developer also needs to post, approve and reply from a dashboard or from Telegram, or you want captions written per network, SOSPosting covers both sides with one account.
Which should you choose?
If what you need is exactly what Upload-Post is built for, use it — the comparison above says where that is. If one upload needs to reach your social feeds and your shop or blog, with the copy written per network and your ad spend reviewed in the same place, that is what SOSPosting does.
