Launching SuperData: people, company, and work email APIs for developers

I'm launching SuperData, an API suite for adding people, company, and work email data to products, AI agents, and CRM workflows.

If you're building a tool that needs to understand the person or business behind a record, the data layer can become a project of its own. A domain, a public professional profile, and an email address are useful starting points, but they don't give your application all the context it needs.

SuperData brings those lookups into one API suite so you can spend more time building the workflow around the data.

What you can build with it

• Company enrichment: get company details and context from a domain.
• People profiles: turn a supported public professional profile into structured data.
• Work email discovery: find a work email from a supported social profile.
• Email validation: check email syntax, domain, and mailbox signals.
• Public post data: add recent public activity to a workflow.

The site also has explorers for search, lookalike companies, tech stacks, and reverse email lookup.

A practical example: enriching a CRM record

Here's one way to use the data in an application:

1. Start with the company domain or a supported professional profile supplied by a user.
2. Request the relevant company or person context.
3. Map the returned fields into your application's schema.
4. Show the useful context alongside the existing record.
5. Apply your own qualification and routing rules before deciding what to update or what action to take.

That's a suggested integration pattern, not a claim that SuperData automatically manages your CRM. Your application owns the decisions and updates.

The same pattern can support an AI agent: fetch structured context before asking it to research an account or suggest a next step.

Handle missing data deliberately

When integrating enrichment, I'd treat missing values as a normal application state. Only update fields when a useful value is returned, and give users a clear way to review the context before it drives an action.

For email checks, distinguish the signals returned by the API from a guarantee that a message will be delivered.

Try it

You can explore the public API demos on the SuperData homepage without signing up. There's also a free email checker.

For an integration, start with the API documentation for endpoints, request examples, and response details, then get API access.

I'd love feedback from developers building enrichment, research, or agent workflows. What input do you usually start with: a domain, a profile URL, or an email address? And what missing field causes the most friction in your application?
