📘 Autobound B2B Data API (Beta)

Autobound’s B2B Data API gives you instant access to millions of decision-makers and company records, filtered by the attributes that matter most to GTM teams and sales product builders.

This API enables you to query enriched contact and company data using flexible filters—helping you power workflows like prospecting, contact recommendation, intent scoring, and CRM enrichment with high-quality B2B signals.

🔍 What You Can Do

With the B2B Data API, you can:

• Fetch decision-makers from companies that fit your ICP.
• Enrich contacts at a given company with role, seniority, and location data.
• Supply your product or CRM with high-quality company metadata and demographics.
• Build contact discovery engines based on persona + firmographic targeting.
• Enable search, filtering, and segmentation for sales, revops, or marketing use cases.

🧠 Who This Is For

• Sales & GTM teams looking to find more buyers, reach the right personas, or enrich inbound interest.
• Product teams building CRMs, enrichment tools, prospecting features, or account intelligence.
• RevOps and Marketing teams powering outbound, segmentation, scoring, or campaign workflows.

🧪 Two Powerful Endpoints

1. /filter-contacts

Search and retrieve individual B2C-style contacts—filtered by name, title, geography, job department, seniority, or even inferred traits like homeownership or net worth.

Example query:

{
  "Filters": [
    { "Column": "JobTitle", "Operator": "contains", "Value": "VP Sales" },
    { "Column": "CompanyDomain", "Operator": "equals", "Value": "microsoft.com" }
  ]
}

2. /filter-b2b

Retrieve company-level firmographic data—like revenue, headcount, NAICS codes, and industry—ideal for targeting and enriching accounts.

Example query:

{
  "Filters": [
    { "Column": "CompanyEmployeeCount", "Operator": "contains", "Value": "5000" },
    { "Column": "CompanyState", "Operator": "equals", "Value": "CA" }
  ]
}

🔐 Authentication

All requests require a valid EchoPath API token.
You can authenticate using:

• Header: x-api-token: <your_token>
• Query param: ?api_token=<your_token>
• JSON body: "api_token": "<your_token>" (optional fallback)

🚧

SortBy is required

Both /filter-contacts and /filter-b2b (companies) require a valid SortBy value in the query string.

If missing or left blank, your request will fail with an error such as "Invalid column name", even if your filters are valid. See each endpoint's section for valid sort fields

✅ Autobound automatically applies a default sort field (SortBy = LastName for contacts, SortBy = CompanyName for companies) unless explicitly overridden. This helps prevent upstream errors and ensures consistent response ordering.
