Threads

Call the Threads API (graph.threads.net) with curl + jq. The connector injects one credential: $THREADS_ACCESS_TOKEN (a long-lived Threads access token with the threads_basic + threads_content_publish scopes). Never echo it.

Resolve the caller's Threads user id once (every publish needs it):

ME=$(curl -sS "https://graph.threads.net/v1.0/me?fields=id,username&access_token=$THREADS_ACCESS_TOKEN")
TID=$(echo "$ME" | jq -r .id)
echo "$ME"     # {"id":"<THREADS_USER_ID>","username":"..."}

Errors are JSON with error.message / error.code — show them verbatim. 401 / OAuthException → the token expired or lacks scope; reconnect the Threads connector.

Publish a post (two-step: create container → publish)

Confirm the text with the user first (it publishes as their real account). Text ≤ 500 characters (emoji counted as UTF-8 bytes).

Step 1 — create a media container. Text-only (guard the 500-byte limit first):

TEXT="Shipping one API for AI images → posters, cards, mockups. https://platform.acedata.cloud #AI #API"
[ "$(printf %s "$TEXT" | wc -c)" -le 500 ] || { echo "text exceeds Threads 500-byte limit — shorten it"; }
CID=$(curl -sS -X POST "https://graph.threads.net/v1.0/$TID/threads" \
  --data-urlencode "media_type=TEXT" \
  --data-urlencode "text=$TEXT" \
  -d "access_token=$THREADS_ACCESS_TOKEN" | jq -r .id)
echo "container=$CID"

Image post — add media_type=IMAGE + a public image_url (Threads cURLs it server-side, so it must be on a public server); video uses media_type=VIDEO + video_url:

CID=$(curl -sS -X POST "https://graph.threads.net/v1.0/$TID/threads" \
  --data-urlencode "media_type=IMAGE" \
  -d "image_url=https://cdn.acedata.cloud/xxxx.jpg" \
  --data-urlencode "text=caption here" \
  -d "access_token=$THREADS_ACCESS_TOKEN" | jq -r .id)

Step 2 — publish the container. Text posts publish immediately; for IMAGE / VIDEO / carousel containers you MUST wait ≥30s first so Threads can fetch/process the upload — publishing too early fails or returns no id:

sleep 30   # REQUIRED for IMAGE / VIDEO / carousel; skip for TEXT-only posts
curl -sS -X POST "https://graph.threads.net/v1.0/$TID/threads_publish" \
  -d "creation_id=$CID" -d "access_token=$THREADS_ACCESS_TOKEN" | jq .
# → {"id":"<THREADS_MEDIA_ID>"}

If threads_publish returns no id, the container isn't ready yet — poll GET /v1.0/<CID>?fields=status&access_token=$THREADS_ACCESS_TOKEN until status=FINISHED, then retry publish.

Get the public URL of the published post and hand it to the user:

curl -sS "https://graph.threads.net/v1.0/<THREADS_MEDIA_ID>?fields=id,permalink&access_token=$THREADS_ACCESS_TOKEN" | jq -r .permalink

Carousel (2–20 items)

Create each child with is_carousel_item=true, then a media_type=CAROUSEL container with children=<ID1>,<ID2>,..., then publish the carousel id. Links: add link_attachment=<URL> (text-only posts, ≤5 links). Topic tag: topic_tag=<TAG>.

List my recent posts

curl -sS "https://graph.threads.net/v1.0/$TID/threads?fields=id,text,permalink,timestamp&limit=20&access_token=$THREADS_ACCESS_TOKEN" | jq '.data'

Gotchas

• 500-char limit; emoji count as their UTF-8 byte length.
• Media must be a public URL — Threads server-side cURLs image_url/video_url; local files won't work. Upload to a public host / cdn.acedata.cloud first.
• Wait ~30s before publishing media containers (text publishes instantly); if threads_publish doesn't return an id, poll GET /<container-id>?fields=status.
• Rate limit: 250 published posts per 24h per profile (a carousel counts as 1).
• Threads tokens differ from Facebook/Instagram tokens — they come from the Threads OAuth flow on graph.threads.net, not graph.facebook.com.

Record the output

After you successfully publish and obtain the live permalink, call the built-in publish_artifact tool ONCE so the user can track it in My Outputs:

publish_artifact(kind="message", channel="threads", title="<title>", url="<the REAL permalink>", status="delivered")

Use the real returned URL — never fabricate one. Call it once per published item, only after delivery is confirmed; skip it (or use status="failed") if publishing failed. See _shared/artifacts.md.
