What is TwitterAPI.io?
TwitterAPI.io is a service that lets your software read public conversations on X, formerly Twitter. Instead of scrolling X by hand, you or your developer can ask for every recent post that mentions a problem, a product or a competitor, and get the results back quickly.
The company describes itself as a public social data API for developers and AI agents. For a marketing team, the useful part is simpler: it turns X from a feed you skim into a list of people and conversations you can act on.
It covers most of what a team would want to read, including:
- Post search with filters and date ranges
- Public profiles, bios and follower lists
- Replies, quotes and reposts of any public post
- Mentions of an account, plus trending topics by region
- Real-time delivery of new posts that match your rules
You don't need an enterprise contract to start. Sign-up takes a Google account and no credit card.
Why do conversations on X matter for marketing?
People say things on X that they would never type into a form on your website. They ask for recommendations, complain about a tool they pay for, and describe the problem you solve in their own words. Each of those posts is a person telling you what they need, at the moment they need it.
Here is the kind of post a small B2B team might want to find:
| What someone posts | What it tells you |
|---|---|
| "Anyone tried [competitor]?" | They are comparing options right now |
| "Just cancelled [competitor]" | They may be looking for a replacement |
| "My cold emails get no replies" | They have the problem, and may not know a fix exists |
| "How do I get my first customers?" | They are asking for help, in public |
These examples are ours, written to show the pattern. Timing is what makes them valuable: an ad reaches people who might care someday, while a post like this comes from someone who cares today. For more on spotting these moments, see our guide to finding people with the problem you solve, and our comparison of keyword alerts and intent scoring.
How does Siela use TwitterAPI.io?
We use it to help Siela's AI SDR find people on X who have a problem our customers can solve. It is one of the sources behind the X side of the product, alongside the other places the agent looks for leads.
In plain terms, it works in four steps:
Search in the buyer's own words
We turn what a customer's buyers actually say, such as "first customers" or "cold outreach", into searches on X.
Find people who use a competitor
When a customer names its competitors, we also look for people who use them, tried them or left them.
Keep real buyers
Most posts on a topic come from people selling something. We filter those out and keep people writing about the problem as their own, who accept direct messages.
Give each lead a reason
Each lead is scored hot, warm or cold with a one-line reason, so the first message can refer to what the person actually said.
Its pricing suits a small team: you pay for the results you get, so a quiet week costs little. Our X channel is still new, so we aren't publishing result numbers yet.
What else can a marketing team do with it?
Lead generation is only one use. The same data can support several parts of a small marketing team's work, and you can start with whichever matters most to you:
| Goal | What to look for on X |
|---|---|
| Find new customers | People asking for a recommendation or describing the problem you solve |
| Learn from competitors | What their users praise, complain about or leave them over |
| Watch your brand | Mentions of your company and product, and replies to your posts |
| Get content ideas | The questions your buyers keep asking, in their own words |
| Find partners | Accounts your audience follows, using public profiles and follower lists |
| Follow your market | Trending topics by region and activity in X communities |
Competitor research is an easy place to start, because it needs no outreach at all. Search a rival's name once a week, note the complaints that repeat, and use them in your positioning and sales conversations. If you do want to reach out on X, our guides to finding customers on X with few followers and writing a cold DM cover the human side.
Why do teams choose TwitterAPI.io?
Price and quick setup stand out. Its site leads with both, and price comes up again and again in the reviews it shows. Pricing is pay-as-you-go, with no subscription required. Its pricing page lists tweets at $0.15 per 1,000, while X's own pay-per-use API lists $0.005 per post read, or $5 per 1,000 at that rate. That makes the list price per post about 33 times lower, as of 1 November 2026.
Here is how the company describes the rest, along with what you should expect to check for yourself:
| What matters | What TwitterAPI.io says |
|---|---|
| Getting started | Start in 5 minutes with Google sign-in, no card and no project approval |
| Speed | Median response under half a second |
| Reliability | 99.99% uptime |
| Coverage | More than 70 endpoints, from search to communities |
| AI tools | A hosted MCP server that gives Claude, GPT, Cursor and other MCP clients live X data |
| Reviews | 4.6 on Trustpilot from 32 reviews, as shown on its homepage |
These are the company's own figures, so try it on your own searches before you rely on them. Reviewers on its site often mention price and responsive support, which is a good sign for a small team without a dedicated developer on call.
How can you try it in about 30 minutes?
You can try it today with the free credits new accounts receive. You will want a developer or an AI coding tool for anything regular, but a first test is simple:
Sign up with Google
Create a free account and copy your API key. New accounts get up to $1 of free credits, with no card, and those credits expire after 31 days.
Pick three phrases your buyers use
Take them from sales calls and support emails, not your homepage. Add one competitor's name.
Run a search
Use the Try it panel in the search docs, or connect the MCP server and ask your AI assistant to run the searches for you.
Read what comes back
Note who is a real buyer, who is selling, and what language people use. The language alone can improve your next landing page.
One thing to check first: TwitterAPI.io describes itself as an independent third-party service, not affiliated with or endorsed by X. Before you build on it, read its terms and X's terms against your own use.
If you'd rather have the whole job done for you, Siela's AI SDR finds people with a fresh reason to buy, starts the conversation on LinkedIn, X and email, and follows up.
Frequently asked questions
What is TwitterAPI.io used for?
Teams use it to read public X data in their own software or AI tools. That can mean finding people who describe a problem, researching what users say about a competitor, tracking brand mentions, or following trending topics. It offers post search, profiles, follower lists, replies, communities and real-time delivery through one API.
Do you need to be a developer to use TwitterAPI.io?
You will want a developer or an AI coding tool for anything regular, because it is an API and not a dashboard for browsing posts. A first test is simpler: the search docs have a Try it panel, and its hosted MCP server can give AI tools such as Claude or Cursor live X data.
Is TwitterAPI.io the official X API?
No. Its site describes it as an independent third-party service that is not affiliated with, endorsed by or sponsored by X Corp. X runs its own API with pay-per-use pricing. Read the terms of both services against your own use before you build a product or a regular workflow on either one.
Is TwitterAPI.io free to try?
New accounts get up to $1 of free credits with no credit card, limited to one per person or network, and those credits expire after 31 days. After that it is pay-as-you-go. Its pricing page lists tweets at $0.15 per 1,000 as of 1 November 2026, so a small test costs very little.
