The AI workflow tool market just got a lot more expensive. Apollo is different: data, enrichment, and sequences

The problem with the current stack

Too many tools.
Too many surprises.

GTM teams are stitching together 5–7 point solutions and paying separately for data, enrichment, workflows, and outreach. When pricing shifts, the whole motion breaks.

💸

Credits that multiply as you scale

Per-row, per-run, per-source fees that compound every quarter. Your budget planning becomes a moving target.

🔗

Tools that don't close the loop

Workflow builders that enrich data but can't send sequences. Enrichment tools that don't own the contact database.

🔒

APIs that aren't actually open

Locked to their UI, no programmatic access to sequences or enrichment. Can't build the automation your GTM actually needs.

📊

Analytics stuck in the product

Performance data you can't pull into your BI stack. Manual exports, stale dashboards, and no single source of truth.

Apollo REST API — Live Today

The API layer your GTM stack
has been missing

Apollo's REST API is available on every plan. Enrich people and companies, search Apollo's full database, manage contacts and accounts, interact with sequences, and log calls — all programmatically. OAuth 2.0 support for partner integrations.

Waterfall Enrichment API

Best-available data.
Automatically.

Apollo's enrichment API supports waterfall logic out of the box — pass run_waterfall_email or run_waterfall_phone and Apollo cascades across connected third-party sources to find the best available data.

  • Single API call triggers multi-source enrichment
  • Emails, mobile phones, and direct lines
  • Credits only consumed when data is returned
  • Bulk enrich up to 10 people per request
  • Full person + company enrichment in one database
# Enrich with waterfall — live today curl --request POST \ --url 'https://api.apollo.io/api/v1/people/match' \ --header 'x-api-key: YOUR_API_KEY' \ --data '{ "email": "sarah@company.com", "reveal_personal_emails": true, "reveal_phone_number": true, "run_waterfall_email": true, "run_waterfall_phone": true} # Returns: verified email, mobile, # title, company, LinkedIn, and more
