X (Twitter) — Analysis & Playbooks
X API Likes, Follows and Quotes: Access and Endpoint Changes
X removed likes, follows and quote-posts from all self-serve API tiers from April 2026. What broke, how to check your tool, and where X rules draw the line.
X Rewards: 500 Verified Followers, 500K Impressions Rule
You need 500 verified followers and 500K verified Home Timeline impressions in 90 days; total impressions don't count. Plus the automation rules.

Read X video limits by API or native upload surface, identify the posting account and media category, and separate successful upload from publication.
X API Media Upload v2: Endpoints and Upload Workflow
X moved chunked media upload to /2/media/upload/initialize, append and finalize. Here are the live paths, checked 2026-09-20, and why old tutorials 404.
Multiple X Accounts With One Phone Number: Setup Limits
Autocomplete ranks the phone-number question above the email one, because phone is the harder gate. What we verified on 2026-09-20, and what X would not serve.
X Lead Generation API: Eligibility and Available Access
X documented its Lead Generation API on 15 September 2026. What actually shipped, why it is an Ads API surface, and what organic accounts really work with.

Three official X pages give three different video limits. One changelog sentence explains why all three are right, and which one governs your upload path.
X Auto Posters: Permissions, API Access and Posting Costs
Before you set up an X auto poster, check three things: what X developer policy says about automated posting, what the pay-per-use API charges per post today, and whether the free built-in scheduler already covers you.
X Auto Post Tool Searches: English and Chinese Terms
Google returns zero autocomplete suggestions for the phrase. The Chinese equivalent has a full family and converts at the highest rate in our search data. That gap is not noise — it tells you where a need lives under a different name.
X API Posting Costs: Requests, Links and Billing Units
X moved to usage-based API pricing for new developers in February 2026, and almost nobody publishes what a single post costs. One scheduler now prints the pass-through rates: about $0.005 a read, up to about $0.200 for a post with a link.
X API Free Tier: Current Credits, Costs and Posting Rules
Read current X API credit incentives and per-use prices. Separate conditional free credits, paid requests and permitted automation before choosing a tool.

X DM Auto-Replies: Permissions and Delivery Troubleshooting
Most DM auto-responders get silently muted by Twitter within 3 days. The fix isn't better copy; it's a boring pacing spec (45-second delay, max 3 replies/day, one rest day) — and why browser-level automations outlast API bots.
X Shadowban Checkers: What a Result Can and Can't Prove
A shadowban checker result doesn't prove an account-wide restriction. What X Help says about search gaps and which evidence to record before acting.
AI Replies on X: Permissions, Review and Workflow Limits
Most AI reply tools get you shadowbanned in under a week. Here’s the system that does the opposite — 5 replies a day, a real persona, no API keys — that kept six accounts alive and pulled real followers.
Twitter DM Auto-Reply Tools: Consent and Workflow Checks
Evaluate X/Twitter DM auto-replies for requested support, opt-outs and handoffs. Separate private messages from public AI replies and content drafting.
