How this service works
B2B data enrichment API: details, customers, partners, vendors and competitors for a given company domain, each with a source link. REST and MCP for AI agents and sales teams.
Output
A JSON array of customer companies associated with the queried domain, each entry typically including the customer company name and a source link substantiating the relationship.
Example use cases
Competitor customer list for sales targeting
“I'm prospecting against HubSpot — can you find me their known customers using hubspot.com so I can figure out who to reach out to?”
Validating a prospect's existing vendor relationships
“Before our demo with Acme Corp, can you check who Snowflake's known customers are using snowflake.com — I want to see if Acme shows up so I know whether to position us as a replacement?”
Building a target account list from a partner's customers
“We're partnering with Stripe — can you fetch the list of known customers for stripe.com so we can identify companies to co-sell into?”

Choose this endpoint when you need to discover who buys from a specific company, especially for B2B sales prospecting, competitive analysis, or partner research.
