Getting Started with the TexAu V3 API

This article explains how to sign up for TexAu, link a payment method, generate your API key, and make your first API call using both the console and Postman.

🎥 Video Walkthrough

Watch this step-by-step video to see how to set up the TexAu V3 API and make your first API calls:

What the TexAu V3 API is used for

The TexAu V3 API is a data engineering toolkit that lets you trigger data enrichments, scrapes, and search waterfalls programmatically. Instead of executing manual tasks, you can use the API to:

  • Consolidate 10+ data providers: A single API key acts as a gateway to multiple search, web scraping, and lead verification networks, eliminating the need to manage different subscriptions.
  • Save up to 4x on data costs: Pay only for raw data results, making it up to 4x cheaper than purchasing individual competing data enrichment tools.
  • Enrich lead lists programmatically: Feed data directly from your CRM, custom scripts, or databases.
  • Run verification waterfalls: Verify B2B emails at send-time, directly within your active flows.

💳 Pricing & 🔒 Data Privacy Policies

To keep operations lean and secure for developers, TexAu enforces the following policies for all API and MCP traffic:

  • Pay-as-you-go Billing (No Monthly Subscription): Unlike the platform subscription tiers, the API and MCP servers have no monthly subscription fees. You only pay for the credits you consume. You can top up manually or configure Auto-Reload to keep your pipelines running.
  • Direct Request Pipeline (No Data Storage): To ensure maximum data privacy and simplify GDPR/CCPA compliance, TexAu does not store any of your request data on its servers. Input parameters, files, and output leads are processed in real-time and returned directly to your system.

Before you begin

To use the TexAu API, you need:

  • An active email address to confirm your TexAu API account
  • A valid payment card to verify identity and unlock free testing credits

Step 1: Sign up and create a team workspace

  1. Go to the TexAu API sign-in page.
  2. Click Don't have an account yet at the bottom of the form.
  3. Enter your email address, password, confirm your password, and click Sign up with email.
  4. Check your email inbox and look for the email from TexAu containing the confirmation link.
  5. Open the email and click the Confirm Email button.
  6. Once redirected, type in a name for your team workspace and click Create Team.

Step 2: Link your payment method

To protect the TexAu API from abuse and ensure high-quality data access, you must add a payment card to your TexAu API account before generating an API key.

Note: Saving your card will not charge you. Rather, verifying your identity instantly grants you 50 free credits for testing.

  1. On the main dashboard, locate the Getting Started progress bar.
  2. Click Generate your first API key (or go to API Keys in the left sidebar).
  3. A payment method prompt will appear. Click Add Payment Method (alternatively, click Add Payment Method at the top of the dashboard).
  4. Enter your card details in the secure Stripe portal and click Save.
  5. Once saved, click the Usage and Credits tab in the sidebar to verify your 50-credit balance.

Step 3: Generate your API key

  1. Go to API Keys in the left sidebar.
  2. Click Create New Key.
  3. Type in a name for your key (e.g., "Postman Testing" or "CRM Integration").
  4. Click Create Key.
  5. Copy the generated key immediately and save it in a safe place.

Warning: Your API key is displayed in full only once at creation. After closing the dialog box, it cannot be recovered.

Step 4: Make your first API call in the console

  1. Go to the API Catalog tab in the left sidebar.
  2. Under the catalog, select any tool of your choice (for example, the Google Maps Places (URL) tool).
  3. Click View Docs to open the tool's developer console.
  4. Open Google Maps in your browser and run a search (e.g., "MNCs in midtown Manhattan").
  5. Copy the search URL from the browser's address bar.
  6. Paste the URL into the Search URL input field in the TexAu console and click Run.
  7. Once the run completes, inspect the output in the Tree view, Raw JSON view, or click Copy to save the dataset to your clipboard.

Step 5: Make a custom API request via Postman

To integrate TexAu into external systems like Postman, you can swap parameters to use different query inputs (like a LinkedIn profile URL):

  1. Go to the API Catalog tab and select the Email Finder tool.
  2. Click View Docs and copy the cURL command template.
  3. Open Postman, click Import, and paste the cURL command.
  4. In the request body, replace the standard domain parameters (domain, first_name, last_name) with a single LinkedIn URL parameter to pull email details directly from their social profile: 
    {
  "url": "https://www.linkedin.com/in/username"
}
  5. Go to the Headers tab in Postman.
  6. Add a header key named x-api-key and paste your generated API key as the value.
  7. Click Send to fetch the verified lead details directly.

Troubleshooting

I get a 401 Unauthorized error.
Ensure that your request headers contain the x-api-key header name exactly as shown, and verify that the API key value has not been revoked.

I lost my API key.
TexAu does not store or display your full API key after the initial generation. Go to Settings > API Keys, revoke the lost key, and click Create New Key to generate a new one.

Stripe portal fails to save my card.
Ensure you are entering a valid, active credit or debit card. Prepaid cards and virtual cards with zero balance may fail verification checks.
