Enrow is available as a native provider on Clay, the data orchestration platform. This guide shows you two ways to enrich contacts with Enrow inside Clay: the native provider (billed in Clay credits) and your own Enrow API key via the HTTP API enrichment (billed in Enrow credits, for more control and better pricing).

​
How do I use Enrow as a native Clay provider?

The fastest way to get started is the native Enrow provider built into Clay. You can run it directly from your Clay tables using your Clay credits — no API key setup required:
ActionClay Credits
Find email0.2 per find
Verify email0.1 per verification
Find phone20 per phone
The native provider covers Enrow’s core actions — Email Finder, Email Verifier, and Phone Finder.

​
How do I use my own Enrow API key in Clay?

For more control and better pricing, use your own Enrow API key directly in Clay via the HTTP API enrichment. This requires a Clay Growth plan (starting at 495/momonthly,495/mo monthly, 446/mo annually — see pricing) which gives you access to HTTP API actions. Authenticate every request with your API key in the x-api-key header — see Authentication for how to find your key.

​
How do I set up the HTTP API enrichment?

Configure an HTTP API enrichment that calls the Enrow Find Single Email endpoint:
  1. Open your Clay table
  2. Click “Add Enrichment” → search for “HTTP API”
  3. Configure the request:
Method: POST
URL: https://api.enrow.io/email/find/single

Headers:
  x-api-key: YOUR_ENROW_API_KEY
  Content-Type: application/json

Body:
{
  "company_domain": /company_domain,
  "fullname": "/first_name /last_name"
}
In Clay, use /column_name to reference columns from your table.

​
How do I retrieve the enrichment results?

The Enrow API is asynchronous — the POST request returns a search ID, and the result is delivered separately. There are two ways to get the result back into Clay: Option A: Webhooks (Recommended) Add a webhook URL in your request so Enrow notifies Clay automatically once the search finishes. See How webhooks work for the notification format: 
{
  "company_domain": /company_domain,
  "fullname": "/first_name /last_name",
  "settings": {
    "webhook": "YOUR_CLAY_WEBHOOK_URL"
  }
}
Option B: Delay + GET
  1. Add a Delay step (5-10 seconds)
  2. Add another HTTP API step to fetch the result with the search ID via the Get Single Result endpoint:
Method: GET
URL: https://api.enrow.io/email/find/single?id={id}
Headers:
  x-api-key: YOUR_ENROW_API_KEY

​
Which Enrow endpoints can I call from Clay?

When using your own API key, you can call any Enrow endpoint from the HTTP API enrichment. The most common ones and their costs in Enrow credits are below — see Credits & billing for the full per-endpoint breakdown:
ActionEndpointEnrow Credits
Find emailPOST /email/find/single1 per found
Verify emailPOST /email/verify/single0.25 per check
Find phonePOST /phone/single50 per found

​
What are the alternatives to Clay?

If Clay’s pricing or table-based model doesn’t fit your stack, two alternatives let you run Enrow enrichment with more flexibility:
Cargo is a more affordable alternative starting at $250/mo. It’s less restrictive and gives you more freedom in orchestration, making it a great option if you want to control your stack costs. The tradeoff is that it’s a bit more technical than Clay’s drag-and-drop tables.See the Cargo integration guide →
The most flexible and cost-effective option is to build your own enrichment workflows using the Enrow API directly. Use our llms-full.txt with Claude or any LLM to generate integration code in minutes.

​
How do I get the most out of Enrow in Clay?

Follow these practices to save credits and maximize deliverability:
Only enrich contacts that are missing data — filter by decision makers, target companies, or contacts without emails. This saves credits.
Set up Enrow as your primary source, then fall back to other providers using Clay’s “Run if” conditions.
Even with Enrow’s determinist verification, run a verification step before campaigns for maximum deliverability.

​
Why is my Clay enrichment failing?

Most issues come from authentication or input data. Here are the most common problems and fixes: “Unauthorized” Error
  • Check your API key is correct
  • Verify it’s in the x-api-key header (not Authorization)
A 401 Unauthorized response means the API key is missing or invalid — see Status codes and Error handling for the full list of responses. No Results Returned
  • Check that the company domain is valid
  • Try with company_name instead
  • Some contacts may genuinely not have findable emails

FAQ

Use the native Enrow provider for the quickest setup and to keep everything billed in Clay credits. Use your own Enrow API key via the HTTP API enrichment when you want more control and better pricing — this requires a Clay Growth plan.
The Enrow API is asynchronous, so the POST request starts the search and returns an id. Retrieve the result with a webhook or by calling the Get Single Result endpoint with that id.
With the native provider, a find email costs 0.2 Clay credits, a verify email costs 0.1, and a find phone costs 20. With your own API key, the same actions cost 1, 0.25, and 50 Enrow credits respectively. See Credits & billing for details.
Enrow runs determinist verification on found emails, including catch-all addresses. For maximum deliverability before a campaign, you can still add a dedicated Email Verifier step.
