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 ![alt](url) 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 back tweet_id and preview_url to your CMS—reducing copy-paste errors versus manual X editor uploads.

Suppose you have a content publishing pipeline:

• Editors maintain article.md in 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_id is 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-shot POST /x/articles/publish exists for simple jobs.

TwitterXAPI’s five-step flow:

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_COOKIE to 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.

5## Workflow
6> **Answer:** **Workflow** 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.

8- Collect tweets from a curated account list
9- Summarize recurring themes
10- Publish the digest as an X Article
11
12![workflow diagram](https://example.com/workflow.png)

Inline 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.

1import { readFile } from "node:fs/promises";
2
3const API_BASE = "https://api.twexapi.io";
4const token = process.env.TWEXAPI_TOKEN;
5const cookie = process.env.X_COOKIE;
6const markdownPath = process.argv[2] || "article.md";
7
8if (!token || !cookie) {
9  throw new Error("Missing TWEXAPI_TOKEN or X_COOKIE environment variable.");
10}
11
12async function request(path, method, body) {
13  const response = await fetch(`${API_BASE}${path}`, {
14    method,
15    headers: {
16      Authorization: `Bearer ${token}`,
17      "Content-Type": "application/json",
18    },
19    body: JSON.stringify(body),
20  });
21
22  const data = await response.json();
23
24  if (!response.ok || data.code !== 200) {
25    throw new Error(`${method} ${path} failed: ${JSON.stringify(data)}`);
26  }
27
28  return data.data;
29}
30
31function inferTitle(markdown) {
32  const h1 = markdown.match(/^#\s+(.+)$/m);
33  return h1 ? h1[1].trim() : "Untitled X Article";
34}
35
36const markdown = await readFile(markdownPath, "utf8");
37const title = process.env.ARTICLE_TITLE || inferTitle(markdown);
38const coverImage = process.env.COVER_IMAGE;
39const visibility = process.env.ARTICLE_VISIBILITY || "Public";
40
41const draft = await request("/x/articles/draft", "POST", { cookie });
42console.log("Draft created:", draft.article_id);
43console.log("Preview URL:", draft.preview_url);
44
45if (coverImage) {
46  const cover = await request(`/x/articles/${draft.article_id}/cover`, "PUT", {
47    cookie,
48    cover_image: coverImage,
49  });
50  console.log("Cover uploaded:", cover.media_id);
51}
52
53await request(`/x/articles/${draft.article_id}/title`, "PUT", {
54  cookie,
55  title,
56});
57console.log("Title set:", title);
58
59const content = await request(`/x/articles/${draft.article_id}/content`, "PUT", {
60  cookie,
61  markdown,
62});
63console.log("Markdown parsed into blocks:", content.blocks);
64
65const published = await request(`/x/articles/${draft.article_id}/publish`, "POST", {
66  cookie,
67  visibility,
68});
69
70console.log("Article published:", published);

Run it:

TWEXAPI_TOKEN="your_token" \
X_COOKIE="auth_token=...; ct0=...; twid=..." \
COVER_IMAGE="https://example.com/cover.png" \
ARTICLE_VISIBILITY="Public" \
node publish-x-article.mjs ./article.md

Omit COVER_IMAGE if you do not need a cover.

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 blocks after Step 4: pause publish if the parsed block count looks wrong.
• Save tweet_id after 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.
