data-enrichment

Original：🇺🇸 English

Translated

Enrich contact and company data using x402-protected APIs. Superior to generic web search for structured business data. USE FOR: - Enriching person profiles by email, LinkedIn URL, or name - Enriching companies by domain - Finding contact details (email, phone) with confidence scores - Scraping full LinkedIn profiles (experience, education, skills) - Searching for people or companies by criteria - Bulk enrichment operations (up to 10 at a time) TRIGGERS: - "enrich", "lookup", "find info about", "research" - "who is [person]", "company profile for", "tell me about" - "find contact for", "get LinkedIn for", "get email for" - "employee at", "works at", "company details" ALWAYS use x402.fetch for enrichx402.com endpoints - never curl or WebFetch. Returns structured JSON data, not web page HTML. IMPORTANT: Never guess endpoint paths. All paths follow the pattern https://enrichx402.com/api/{provider}/{action}. Use exact URLs from the Quick Reference table below or call x402.discover_api_endpoints first.

Data Enrichment with x402 APIs

STOP — Read before making any API call. enrichx402.com endpoints are not the same as each provider's native API. All paths use the format
https://enrichx402.com/api/{provider}/{action}
. You MUST either:
Copy exact URLs from the Quick Reference table below, OR
Run
x402.discover_api_endpoints(url="https://enrichx402.com")
to get the correct paths
Guessing paths will fail with 405 errors (wrong path) or 404 errors (missing
/api/
prefix).

Use the x402scan MCP tools to access enrichment APIs at enrichx402.com.

Setup

See rules/getting-started.md for installation and wallet setup.

  method="POST",
  body={
    "people": [
      { "email": "person1@company.com" },

      { "linkedin_url": "https://linkedin.com/in/person3" }
    ]
  }
)

mcp

x402.fetch(
  url="https://enrichx402.com/api/apollo/org-enrich/bulk",
  method="POST",
  body={
    "organizations": [
      { "domain": "company1.com" },
      { "domain": "company2.com" }
    ]
  }
)

Cost Optimization

Field Filtering

Reduce costs by excluding unneeded fields:

body={
  "email": "john@company.com",
  "excludeFields": ["employment_history", "photos", "phone_numbers"]
}

Common fields to exclude:

```
employment_history
```
- Past jobs (often large)
```
photos
```
- Profile images
```
phone_numbers
```
- If you only need email
```
social_profiles
```
- If you don't need social links

Bulk vs Individual

Individual: $0.0495 per record
Bulk (10): $0.495 total = $0.0495 per record

Bulk is the same price per record but faster for multiple items.

Search Before Enrich

Use search endpoints ($0.02) to find the right records before enriching ($0.0495):

Search for candidates:
```
/api/apollo/people-search
```
Review results, pick the right match
Enrich only the matches you need

Parallel Calls

When enriching multiple independent records, make calls in parallel:

mcp

# These can run simultaneously since they're independent
x402.fetch(url=".../people-enrich", body={"email": "a@co.com"})
x402.fetch(url=".../people-enrich", body={"email": "b@co.com"})

Or use bulk endpoints for the best efficiency.

Handling missing data

If any query fails to return the data you are looking for, revist the list of available APIs.

Oftentimes, if apollo is missing data, clado will have it, and vice versa.

If those still fail, use built-in WebSearch and WebFetch tools to find additional information like a company domain name or LinkedIn URL, and then use that data to make more targeted queries.
