Seamless Makes API Access Available on Every Plan as AI Agents Reshape B2B Prospecting

While legacy B2B data providers gate API access behind enterprise contracts, Seamless is opening programmatic access to verified contact data, company intelligence, and enrichment workflows to every user, sales team, RevOps, engineers, and the AI agents they’re building.

Seamless, the AI-powered B2B sales intelligence platform used by revenue teams to find, enrich, and convert pipeline, announced today that its public API is now included on every Seamless plan. Free accounts included, making it one of the only sales intelligence platforms in the category to put programmatic access in the hands of every customer rather than restricting it to enterprise tiers.

The launch lands as revenue teams retool around AI: cold outbound is collapsing, deliverability is tightening, and buyers expect the right contact at the right moment, not bigger contact lists. Increasingly, that work is being handled by AI sales agents and custom workflows that demand real-time, programmatic access to data. Exactly what an API-first model unlocks.

“The B2B data category has spent fifteen years selling access to lists. That era is ending,” said Brandon Bornancin, CEO at Seamless. “AI agents don’t read CSVs. They call APIs.”

Seamless API gives every account programmatic access to the same verified contact data, company intelligence, firmographics, and enrichment capabilities that power the Seamless platform. With it, teams can:

• Find verified B2B contacts and companies programmatically, without manual prospecting
• Enrich CRM records, data warehouses, and internal systems with verified emails, phone numbers, titles, and firmographics
• Trigger buyer intent and list-building workflows inside existing revenue tools
• Power AI agents and custom applications with real-time sales intelligence
• Eliminate manual research and data entry across sales, marketing, and RevOps

Free-tier users receive an API key on signup; API calls draw from each plan’s existing credit balance, so customers don’t pay separately for API access on top of their subscription.

Built for the way revenue teams actually work in 2026.

The shape of go-to-market work is changing. Sales teams are running AI-driven prospecting agents. Marketing teams are stitching real-time enrichment into ABM platforms. RevOps is rebuilding CRM hygiene as an automated pipeline rather than a quarterly project. Developers are building internal tools their reps log into instead of buying off-the-shelf SaaS for every workflow.

All of that requires APIs. Vendors who keep their data behind a single web UI or behind a procurement gate are increasingly cut out of the workflows their customers are building.

“Sales intelligence is only as valuable as the systems it can plug into,” said Jake Phillips, VP of Product at Seamless. “Seamless API turns our data into a building block. Reps still get the experience they know in the Seamless app. But ops teams, developers, and AI builders now get a native way to put Seamless wherever their team actually works, Salesforce, HubSpot, Snowflake, Outreach, Clay, custom agents, anywhere.”

Use cases the API supports

• Automated CRM and database enrichment at scale
• Real-time contact and company lookup inside sales engagement and marketing automation tools
• Custom prospecting agents and AI-driven outbound workflows
• ABM list-building and account scoring pipelines
• Audience segmentation and lifecycle marketing enrichment
• Internal applications and revenue dashboards powered by live B2B data
