Post types

TypeEndpointPlatforms (typical)

Multi-platform example

curl -X POST "https://backend.postsiva.com/unified/post/text" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: psk_live_YOUR_KEY" \
  -d '{
    "platforms": ["linkedin", "threads", "bluesky"],
    "default_text": "Shipping our latest update."
  }'
Each platform returns its own result. One failure does not roll back the others.
