Clay HTTP API Integration

Overview

Clay’s HTTP API enrichment lets you call any external API directly from your table. By connecting Anysite endpoints, you replace Clay’s native data credit–consuming enrichments with direct API calls — keeping the same workflow but removing the data credit cost. What moves off Clay’s data credits:

LinkedIn profiles and company data
Website scraping and content extraction
Twitter/X user data and posts
Company employee search
Reddit, Instagram, YouTube data

What stays in Clay (worth the credits):

Email verification waterfall
Phone number enrichment

Requirements: Clay Growth plan or higher (HTTP API is not available on Starter/Launch). Anysite API key from app.anysite.io.

Step 1: Get Your Anysite API Key

Go to app.anysite.io and create an account. Free tier includes 1,000 credits to test.

Copy your API key

In the dashboard, find your API key in the API Key section. You’ll use this as the access-token header value in Clay.

Step 2: Prepare Your Clay Table

Create or open a Clay table with your lead data. You need at least one column with identifiers — LinkedIn URLs, company domains, or Twitter handles.

Clay table with Domain and LinkedIn URL columns

Click + Add column to start adding an enrichment.

Step 3: Add HTTP API Enrichment

Select Add enrichment from the column menu, then search for HTTP API.

Search for HTTP API in Clay enrichment tools

Select HTTP API (Enrichment · Clay).

Step 4: Configure the API Call

Clay offers two ways to set up the HTTP API connection: Generate (AI-assisted) and Configure (manual).

Option A: AI-Generated Setup (Recommended)

The Generate tab uses Clay’s Sculptor AI to automatically configure the API call. Instead of writing the prompt yourself, copy a ready-made prompt from the Anysite API Reference. 1. Open the endpoint page in Anysite API Reference Find the endpoint you need (e.g. /linkedin/company) and click the Copy AI Prompt button next to the endpoint title.

Anysite API Reference — Copy AI Prompt button on endpoint page

This copies a detailed prompt with the endpoint URL, authentication method, all parameters, request/response examples, and implementation requirements. 2. Paste the prompt into Clay’s Generate field In the HTTP API dialog, switch to the Generate tab and paste the copied prompt into the description field. You don’t need to fill in the Documentation URL — the prompt already contains everything Sculptor needs.

Clay HTTP API Generate tab — paste the AI prompt

Click Generate API Connection. Sculptor reads the prompt and configures the method, endpoint, headers, and body mapping automatically. 3. Review the generated connection

The generated connection shows:

access-token field — paste your Anysite API key here
company field — mapped to your table’s LinkedIn URL column
timeout — optional, leave empty for default (300s)

The Copy AI Prompt button is available on every endpoint page in the API Reference. Use it for any Anysite endpoint — LinkedIn, Twitter, Instagram, Reddit, YouTube, web scraping, and more.

Option B: Manual Configuration

Switch to the Configure tab to set up the API call manually.

Fill in:

Method: POST
Endpoint: https://api.anysite.io/api/linkedin/company
Account: Add HTTP API (Headers) account with access-token: YOUR_API_KEY
Body: {"company": "{{linkedin_url_column}}"}

Use the / key in any field to insert column references from your table.

Step 5: Map Response Fields

After running the enrichment, Clay returns structured JSON. Use Clay’s JSON path selector to extract specific fields into new columns:

$.name — company name
$.description — company description
$.industry — industry
$.employee_count — employee count
$.headquarters — headquarters location
$.website — company website

Common API Configurations

LinkedIn Company Profile

POST https://api.anysite.io/api/linkedin/company
Body: { "company": "{{linkedin_url}}" }

Returns: name, description, industry, employee count, headquarters, specialties, recent posts.

LinkedIn Person Profile

POST https://api.anysite.io/api/linkedin/user
Body: { "user": "{{linkedin_profile_url}}" }

Returns: full profile with experience, education, skills, current role.

Find Decision Makers

POST https://api.anysite.io/api/linkedin/search/users
Body: {
  "keywords": "CTO",
  "company_keywords": "{{company_name}}",
  "count": 5
}

Returns: list of matching profiles with LinkedIn URLs.

Website Scraping

POST https://api.anysite.io/api/webparser/parse
Body: {
  "url": "{{website_url}}",
  "strip_all_tags": true,
  "only_main_content": true
}

Returns: clean text content. Feed into a Clay AI column to extract tech stack, signals, or any structured data.

Twitter/X User Posts

POST https://api.anysite.io/api/twitter/user/posts
Body: {
  "user": "{{twitter_handle}}",
  "count": 20
}

Returns: recent posts with engagement metrics — useful for identifying active companies and buying signals.

Company Employees

POST https://api.anysite.io/api/linkedin/company/employees
Body: {
  "companies": [{ "type": "company", "value": "{{company_urn}}" }],
  "count": 10
}

Requires company URN from the /api/linkedin/company response. Run company enrichment first, extract the URN, then use it here.

Example Workflow: B2B Lead Enrichment

A typical 5-column enrichment pipeline:

Column	Source	What it does	Clay cost
LinkedIn URL	Input	Your lead list	Free
Company Data	Anysite API	`POST /api/linkedin/company`	1 Action
Person Profile	Anysite API	`POST /api/linkedin/user`	1 Action
Website Content	Anysite API	`POST /api/webparser/parse`	1 Action
Email	Clay native	Email waterfall enrichment	1 Action + credits
AI Summary	Clay AI	Personalized first line	1 Action

Result: Full lead enrichment where only email verification uses Clay data credits. LinkedIn and web scraping are handled by Anysite at API plan cost ($49/mo for ~5,000 calls).

Cost Comparison

For a 1,000-lead monthly workflow with LinkedIn + website + email enrichment:

Approach	Monthly cost
Clay native only (Growth plan)	~$2,200
Clay + Anysite API	~$375

The difference comes from eliminating ~15,000 data credits on LinkedIn profiles and website scraping.

Troubleshooting

HTTP API requires Growth plan or higher

Clay’s HTTP API enrichment is only available on Growth plan and above. If you see “Feature not available! Please upgrade your plan”, you need to upgrade your Clay subscription.Alternative: Use Clay MCP integration instead — MCP works on all Clay plans that support custom MCP servers.

401 Unauthorized errors

Anysite uses access-token header, not Authorization: Bearer.When setting up the HTTP API account in Clay:

Header name: access-token
Header value: your API key from app.anysite.io

Empty or missing data in response

Verify the input URL/identifier is correctly formatted
Check that the LinkedIn profile or company page exists and is public
Some profiles may return limited data if they are private
Error code 404 means the entity was not found — verify the URL
Error code 412 means the entity is unavailable (deleted or restricted)

See Error Codes for the full list.

Sculptor generates incorrect configuration

If the AI-generated setup doesn’t work:

Switch to the Configure tab and set up manually
Use the exact endpoint URLs from this guide
Make sure access-token is set as a header, not a query parameter
Verify the JSON body field names match the API documentation

Rate limits or timeout errors

Default timeout is 300 seconds. Add "timeout": 600 to the body for slow requests
If you get 429 errors, reduce request frequency or check your plan limits
Check usage at app.anysite.io dashboard
