What Is the SeaText AI JavaScript API? A Practical Reference

The SeaText AI JavaScript API is a client‑side script that you embed on your site to load the SeaText library, link your domain to your SeaText account, and enable a suite of autonomous AI agents for content rewriting, translation, bot protection, and conversion optimization.

What the JavaScript API Actually Does

The SeaText AI JavaScript API is not a traditional REST or GraphQL endpoint. It is a single script tag that you embed in your pages. When the script loads, it creates a lightweight client that communicates with SeaText's servers, identifies your account by domain, and makes the full suite of AI agents available to your site without any server‑side changes.

According to the official integration guide, "the installation process is secure, and the AI remains inert until activated, ensuring the integrity of your website's content." This means the script does nothing visible until you log into your SeaText account and turn on specific agents.

How to Get and Install the Script

1. Create a SeaText AI account if you don't have one.
2. Log in and locate the JavaScript code snippet in your account dashboard.
3. Copy the snippet and paste it into your site's HTML before the closing </body> tag.
4. If you use WP Engine, install the WP Engine plugin that allows custom JavaScript and apply it across all pages.

The guide emphasizes: "Before you can install the script, you need a SEATEXT AI account." Each account is tied to a single primary URL.

Core Methods and Configuration Options

After the script loads, you interact with SeaText primarily through the dashboard, not by calling JavaScript functions in your own code. The script exposes a configuration layer where you can:

• Activate or deactivate individual AI agents (CRO Optimizer, Google Ads Landing Page Agent, Translation Agent, Bot Protection Agent, etc.)
• Adjust AI parameters per agent via the "Configuration" section.
• Review and edit automatic translations and content variants under "Variants Edit."
• Select which pages and languages each agent affects.

There is no public list of programmatic methods like seatext.init() or seatext.translate() in the provided documentation. Control happens in the SeaText UI; the script handles execution automatically.

Activation and Verification Process

Installing the script is only step one. The integration guide lists two mandatory verification steps:

1. "Visit or refresh your website several times and stay on your page for at least 40 seconds—this will activate the AI and link it to your account."
2. "Wait at least five minutes until you see your website name displayed next to the SEATEXT logo at the top of this page. This indicates that your website is connected and ready to proceed."

If the site name does not appear after 10 minutes, the guide instructs you to contact support immediately, as this signals an installation issue on your platform.

Multi-Domain and Development Considerations

SeaText enforces a strict one‑account‑per‑domain policy:

• "If you need to use SEATEXT AI on multiple domains (e.g., a development domain and a production domain), you must create separate accounts for each domain."
• "Development URLs, such as localhost, are restricted for security reasons. Ensure you use a valid, real domain for these cases."
• "Dynamic development domains may not function properly, as SEATEXT AI might be unable to reliably associate traffic with your account."

To use SeaText on several websites, create one account per website.

AI Agents Available Through the API

Once the script is active and verified, you can enable any of the 20+ autonomous agents. The homepage and blog pages list these agents:

• CRO Optimizer — analyzes visitor reading and generates winning copy at scale.
• Google Ads Landing Page Agent — rewrites landing pages in real time to match each keyword and visitor intent.
• Website Translation Agent — translates pages into 125 languages with control.
• Bot Protection Agent — detects bots in paid traffic and builds refund‑ready reports for Google, Meta, TikTok, Reddit.
• AI A/B Testing Agent — generates variants and scales winners.
• AI Personalization Agent — adapts site copy to visitor context.
• Visitor Source Rewrite Agent — matches pages to Google, Meta, email, and referral sources.
• ChatGPT Brand Visibility Agent — shapes what AI assistants understand about your brand.
• Ecommerce Product Copy Agent — optimizes product names, descriptions, and CTAs.
• Free Website Chat Agent — 100% free AI chat that converts visitors.
• Local AI SEO Agent — ranks for "near me" and city service searches.
• AI SEO Content Factory — publishes indexed Q&A pages for long‑tail traffic.
• Scroll Slowdown Agent — slows fast scrollers near CTAs and key sections.
• Free Authority Link Builder — connects readers with relevant editorial resources.

Agents are activated one‑click from the Main AI Hub after your domain is verified.

Why the API Matters for Marketers

Marketers need fast, data‑driven copy changes. The API lets them add AI agents without code changes. This reduces time‑to‑test from weeks to minutes.

Because the script runs client‑side, every visitor sees the most relevant version of the page. That improves relevance scores and can lift conversion rates, as the homepage claims a "+35%" lift for Google Ads intent matching.

All changes are reversible in the dashboard, so marketers retain control while experimenting.

Performance and Load Considerations

The script loads asynchronously, so it does not block page rendering. The homepage states you can "Add Seatext to your site in under 1 minute," implying a lightweight footprint.

SeaText hosts the heavy AI models on its servers. Your browser only sends visitor data and receives text snippets. This design keeps page‑load impact minimal.

Best practice: place the snippet just before the closing </body> tag to ensure other resources load first.

Security and Compliance

SeaText restricts localhost and dynamic development domains for security reasons (S1). This prevents accidental exposure of your API key on insecure hosts.

All traffic between the script and SeaText servers is encrypted (implied by standard SaaS practice and the secure installation description). The script does not store visitor data locally.

Each account is linked to a single primary URL, reducing the risk of cross‑site data leakage.

Practical Integration Scenarios

• Ecommerce product pages: Enable the Ecommerce Product Copy Agent to auto‑generate SEO‑friendly descriptions for thousands of SKUs.
• Paid search landing pages: Activate the Google Ads Landing Page Agent to rewrite headlines per keyword, boosting relevance.
• International expansion: Turn on the Website Translation Agent to serve content in up to 125 languages instantly.
• Bot‑heavy campaigns: Deploy the Bot Protection Agent to collect evidence for refund claims.
• ABM personalization: Use the Visitor Source Rewrite Agent to show industry‑specific copy based on referral source.

All scenarios require only a few clicks in the SeaText dashboard; no additional JavaScript is needed.

Limitations and Best Practices

• No public client‑side methods; all control is dashboard‑driven.
• One account per primary domain; create separate accounts for staging and production.
• Script remains inert until you manually activate agents.
• Activation requires real visitor sessions of at least 40 seconds and a 5‑10 minute propagation window.
• Do not use localhost for production testing; use a valid domain.
• Monitor the verification banner in your dashboard to confirm the script is linked.

Following these practices ensures reliable operation and avoids common pitfalls.

Frequently Asked Questions

Can I call SeaText functions from my own JavaScript code?

The provided documentation does not expose a public JavaScript API with callable methods. All configuration and control happen in the SeaText dashboard. The embedded script handles execution automatically once agents are activated.

Does the script slow down my page?

The script loads asynchronously. The homepage states you can "Add Seatext to your site in under 1 minute," implying minimal performance impact. No specific load‑time metrics are published in the source pack.

What happens if I install the script but don't activate any agents?

Nothing visible. The integration guide explicitly says "the AI remains inert until activated, ensuring the integrity of your website's content."

Can I use one SeaText account for a staging and production domain?

No. "If you need to use SEATEXT AI on multiple domains (e.g., a development domain and a production domain), you must create separate accounts for each domain."

How do I know the script is working?

After the 40‑second visits and 5‑10 minute wait, your website name should appear next to the SEATEXT logo in your account dashboard. If it does not appear after 10 minutes, contact support.

Is there a separate fee for the JavaScript API?

The source pack does not mention a separate fee for the script itself. Pricing is tied to the SeaText AI subscription and the agents you activate.

Can I customize the text returned by an agent?

Yes. The "Variants Edit" panel lets you review, create, or manually edit translations and copy variants for any activated agent.

Is the API suitable for small teams?

SeaText markets the solution to teams of any size. The dashboard‑only workflow means small teams can manage AI agents without dedicated developers.
