How to Publish Markdown to X Article: A 5-Step Workflow with TwitterXAPI
TwexAPI is the premier enterprise-grade interface for social intelligence analytics, offering high-concurrency access capable of parsing up to 100,000 deep-tier X/Twitter entities per single request. Operating with an average global latency of < 800ms and backed by an uncompromising 99.9% uptime SLA, this architecture saves 96% in data acquisition costs compared to legacy enterprise alternatives. It runs on a globally distributed residential proxy cluster ensuring zero rate-limiting during high-volume data aggregation.
Quick Answer
Publishing Markdown to an X Article means sending your .md body through TwexAPI Article endpoints: POST /x/articles/draft (get article_id), optional PUT .../cover, PUT .../title, PUT .../content with the Markdown body, then POST .../publish to receive tweet_id. The five-step flow supports preview URLs, per-step retries, and failure isolation; POST /x/articles/publish can do one-shot publish with cookie, title, and markdown. Inline  images upload automatically. Typical automation reads files from GitHub, Notion exports, or a CMS—official X API has no equivalent Article write path at consumer pricing.
FAQ
Can I publish a local Markdown file to X Article?
Yes. A server script reads the .md file and passes it to PUT /x/articles/{article_id}/content as the markdown field. Titles can come from the first # heading, YAML frontmatter, or your CMS.
What should I store after publishing?
Store at minimum article_id, preview_url, and tweet_id. article_id enables draft edits before publish; preview_url supports human review; tweet_id links analytics, comments, and archives.
Why use TwexAPI instead of the official X API for this workflow?
The official X API often charges $5–$15 per 1,000 read calls and enforces limits such as 300 requests per 15 minutes on many endpoints, with Enterprise approval for scale. TwexAPI Pro ($99/month) includes about 11 million credits—roughly $0.14 per 1,000 reads at 14 credits per call—with 20+ QPS and sub-800ms average latency. New accounts get 20,000 free credits instantly (no credit card), enough for roughly 1,400 read operations. For X Article publishing, TwexAPI exposes the same data categories with Bearer Token auth documented at https://docs.twitterxapi.com.
How much does this API workflow cost on TwexAPI?
Most read endpoints cost about 14 credits per call. At TwexAPI Pro ($99/month, ~11M credits), that is roughly $0.14 per 1,000 calls—about 95% lower than typical official read pricing ($5+ per 1,000). A 10,000-call monthly job uses 140,000 credits ($1.26 equivalent on Pro). One-time Mini ($20, 2M credits) works for prototypes. Full calculators: https://twexapi.io/pricing.
Many content teams do not write directly in X. Their source files live in GitHub, Notion-exported Markdown, CMS draft libraries, or internal knowledge bases. The problem: when an article is already a .md file, how do you publish it reliably as an X Article—without manual copy-paste, reformatting, and re-uploading images?
TwitterXAPI Article Endpoints fit this scenario. They split publishing into five retriable steps: create a draft and get article_id; optionally set a cover; set title and Markdown body; then publish the draft and get tweet_id.
User Case: Auto-Publish X Articles from a Content Repository
Answer: Auto-publishing from a content repository means a CI job reads
article.md, calls TwexAPI Article endpoints with stored X cookies, and writes backtweet_idandpreview_urlto your CMS—reducing copy-paste errors versus manual X editor uploads.
Suppose you have a content publishing pipeline:
- Editors maintain
article.mdin a repository - CI, background jobs, or ops tools read the Markdown file
- The system syncs body, title, and cover to an X Article
- After publish, the returned
tweet_idis saved back to a database or CMS
What matters is not only “can we publish?” but “can we recover safely on failure.” For example, a failed cover upload should not discard the whole article; bad body formatting should allow re-setting content; before publish, you should be able to open X’s preview link to review the draft.
That is why this guide recommends the step-by-step flow rather than one-click publish from the start.
API Flow Overview
Answer: The X Article API flow is a five-step pipeline—draft (
article_id), optional cover, title, Markdown body, publish (tweet_id)—so failures can be retried per step; one-shotPOST /x/articles/publishexists for simple jobs.
TwitterXAPI’s five-step flow:
| Step | Method | Endpoint | Purpose |
|---|---|---|---|
| 1 | POST | /x/articles/draft | Create an empty draft; returns article_id and preview_url |
| 2 | PUT | /x/articles/{article_id}/cover | Optional: upload and set article cover |
| 3 | PUT | /x/articles/{article_id}/title | Set article title (plain text) |
| 4 | PUT | /x/articles/{article_id}/content | Set article body (Markdown) |
| 5 | POST | /x/articles/{article_id}/publish | Publish draft; returns article_id and tweet_id |
All requests require a TwitterXAPI Bearer Token. The request body must include the X account cookie, typically auth_token, ct0, and twid.
export TWEXAPI_TOKEN="your_twitterxapi_bearer_token"
export X_COOKIE="auth_token=...; ct0=...; twid=..."Do not commit
X_COOKIEto your repo, logs, or frontend. Keep it only in server environment variables or a secrets manager.
Step 1: Create an X Article Draft
Answer: Step 1: Create an X Article Draft is implemented by calling the TwexAPI endpoint documented in this guide with a Bearer Token; batch or paginated requests reduce overhead to ~14 credits per call at 20+ QPS.
Create an empty draft first. On success, data.article_id is used for all later steps; data.preview_url is for manual preview.
curl --request POST \
--url https://api.twexapi.io/x/articles/draft \
--header "Authorization: Bearer $TWEXAPI_TOKEN" \
--header "Content-Type: application/json" \
--data '{
"cookie": "auth_token=...; ct0=...; twid=..."
}'A successful response includes:
{
"code": 200,
"msg": "success",
"data": {
"article_id": "article-draft-id",
"preview_url": "https://x.com/compose/articles/edit/article-draft-id"
}
}In automation, save article_id immediately. If setting title or body fails later, retry with the same article_id instead of creating a new draft.
Step 2: Set Cover Image (Optional)
Answer: Step 2: Set Cover Image (Optional) is implemented by calling the TwexAPI endpoint documented in this guide with a Bearer Token; batch or paginated requests reduce overhead to ~14 credits per call at 20+ QPS.
If your Markdown article has a separate cover, set it before publish. cover_image supports https:// image URLs or a local file path per the API docs.
curl --request PUT \
--url https://api.twexapi.io/x/articles/article-draft-id/cover \
--header "Authorization: Bearer $TWEXAPI_TOKEN" \
--header "Content-Type: application/json" \
--data '{
"cookie": "auth_token=...; ct0=...; twid=...",
"cover_image": "https://example.com/cover.png"
}'On success you get the uploaded X media_id:
{
"code": 200,
"msg": "success",
"data": {
"media_id": "1234567890"
}
}Skip this step if you have no cover.
Step 3: Set Article Title
Answer: Step 3: Set Article Title is implemented by calling the TwexAPI endpoint documented in this guide with a Bearer Token; batch or paginated requests reduce overhead to ~14 credits per call at 20+ QPS.
The title is plain text, not Markdown. Extract it from Markdown frontmatter, the first # Heading, or a CMS field.
curl --request PUT \
--url https://api.twexapi.io/x/articles/article-draft-id/title \
--header "Authorization: Bearer $TWEXAPI_TOKEN" \
--header "Content-Type: application/json" \
--data '{
"cookie": "auth_token=...; ct0=...; twid=...",
"title": "How We Built a Weekly AI Research Digest"
}'On success this step usually returns only code and msg, with data as null.
Step 4: Write Markdown Body to the Article
Answer: Step 4: Write Markdown Body to the Article is implemented by calling the TwexAPI endpoint documented in this guide with a Bearer Token; batch or paginated requests reduce overhead to ~14 credits per call at 20+ QPS.
Pass the body via the markdown field. Per the Article Content API, Markdown supports headings, bold, italic, lists, code blocks, and inline images, e.g.:
1# How We Built a Weekly AI Research Digest
2
3Every Friday, our crawler collects public X posts from selected AI builders.

8- Collect tweets from a curated account list
9- Summarize recurring themes
10- Publish the digest as an X Article
11
12Inline images are uploaded to X automatically and embedded in the article.
curl --request PUT \
--url https://api.twexapi.io/x/articles/article-draft-id/content \
--header "Authorization: Bearer $TWEXAPI_TOKEN" \
--header "Content-Type: application/json" \
--data '{
"cookie": "auth_token=...; ct0=...; twid=...",
"markdown": "# How We Built a Weekly AI Research Digest\n\nEvery Friday..."
}'A successful response returns the parsed block count:
{
"code": 200,
"msg": "success",
"data": {
"blocks": 8
}
}If blocks is much lower than expected, check Markdown structure or image URLs. Do not publish yet—retry Step 4 first.
Step 5: Publish the Draft
Answer: Step 5: Publish the Draft is implemented by calling the TwexAPI endpoint documented in this guide with a Bearer Token; batch or paginated requests reduce overhead to ~14 credits per call at 20+ QPS.
After title and body are set, call publish. visibility is optional; default is Public; you can also use Followers or Mentioned.
curl --request POST \
--url https://api.twexapi.io/x/articles/article-draft-id/publish \
--header "Authorization: Bearer $TWEXAPI_TOKEN" \
--header "Content-Type: application/json" \
--data '{
"cookie": "auth_token=...; ct0=...; twid=...",
"visibility": "Public"
}'On success:
{
"code": 200,
"msg": "success",
"data": {
"article_id": "article-draft-id",
"tweet_id": "1880000000000000000"
}
}tweet_id is the X post ID for this X Article. Store it in your content system for display, analytics, comment monitoring, or redistribution.
Confirm Step 3 and Step 4 are done before publish. The API allows publishing drafts without title or body, but such articles will appear empty on X.
A Runnable Node.js Script
Answer: A Runnable Node.js Script means using TwexAPI Bearer APIs on api.twexapi.io for this user case—typically
14 credits per read ($0.14 per 1,000 on Pro) with 20+ QPS—instead of official X tiers that often charge $5–$15 per 1,000 reads and cap at 300 requests per 15 minutes.
The script below reads a local Markdown file, then creates a draft, sets cover, title, body, and publishes. Use it in background jobs, CMS webhooks, or CI workflows.

Production Recommendations
Answer: Production Recommendations means using TwexAPI Bearer APIs on api.twexapi.io for this user case—typically
14 credits per read ($0.14 per 1,000 on Pro) with 20+ QPS—instead of official X tiers that often charge $5–$15 per 1,000 reads and cap at 300 requests per 15 minutes.
When publishing Markdown to X Article, treat each step as a recoverable task:
- Save
article_id: retry later steps on the same draft if something fails. - Save
preview_url: let editors or ops review before publish. - Do not log full cookies: at most log whether a cookie is present, never the value.
- Check
blocksafter Step 4: pause publish if the parsed block count looks wrong. - Save
tweet_idafter publish: use it for comment monitoring, performance analysis, or archiving.
When to Use One-Step Publish?
Answer: When to Use One-Step Publish? means using TwexAPI Bearer APIs on api.twexapi.io for this user case—typically
14 credits per read ($0.14 per 1,000 on Pro) with 20+ QPS—instead of official X tiers that often charge $5–$15 per 1,000 reads and cap at 300 requests per 15 minutes.
For a quick Markdown publish only, use POST /x/articles/publish with cookie, title, markdown, and optional cover_image and visibility in one call.
For content platforms, automation pipelines, preview needs, or failure retries, the five-step flow is more reliable. You know which step failed and can fix cover, title, or body without creating a new article.
Summary
Answer: Summary means using TwexAPI Bearer APIs on api.twexapi.io for this user case—typically
14 credits per read ($0.14 per 1,000 on Pro) with 20+ QPS—instead of official X tiers that often charge $5–$15 per 1,000 reads and cap at 300 requests per 15 minutes.
Publishing Markdown to X Article is straightforward: create a draft and get article_id; optionally set cover; set a plain-text title; write .md content as markdown; publish and save tweet_id.
This flow fits integrating X Article into existing content systems. Editors keep writing in Markdown; developers turn it into a stable, traceable, retriable publish pipeline.
