Developers & API

The same source-cited data, straight from the API.

Search the contact index programmatically by name, title, seniority or domain — every record carrying the same source URL you see in-app. No scraping, no maintenance.

REST API on higher plans · Same data as the app

The problem

Scraping doesn't scale.

Building your own contact data pipeline means crawlers to babysit, parsers that break every time a site changes, and no way to prove where a field came from. It's a maintenance tax that grows with every source you add.

Rolling your own

Crawlers and parsers that break when sites change
Every source in a different, inconsistent shape
No provenance to prove where a field came from
Engineering time spent on plumbing, not product

See it in action

A search is one request.

Every result carries the contact and the public page it came from — the same provenance you see in the app.

search.sh

# Search contacts by title and seniority
curl "https://api.datasigma.io/v1/contacts/search?title=Head%20of%20Sales&seniority=director" \
  -H "Authorization: Bearer $API_KEY"

# → 200 OK
{
  "results": [
    {
      "name":       "Jordan Lee",
      "title":      "Head of Sales",
      "company":    "Acme Inc.",
      "source_url": "https://acme.com/team"
    }
  ]
}

What you get

Endpoints built for production.

Contact search

Query the contact index by name, title, seniority and domain — the same filters you use in the app.

Find contacts by domain

Pass a company domain to pull the people we hold at that company — ideal for enriching accounts you already work.

Structured JSON responses

Every record comes back in the same schema you see in the app — easy to map straight into your own models.

Source URL on every record

Each response includes the public page the data came from — provenance your compliance team can rely on.

Same data as in-app

The API returns the exact records you see in the dashboard — no separate, lower-quality feed to reconcile.

Built for warehouses & tooling

Pipe source-cited records straight into your data warehouse, CRM sync or internal tools — no scraping to maintain.
