ProspectsAlpha
Tell us what you sell and where you want to sell it, and the team builds you a verifiable list of business prospects.
Alpha feature: Prospects is a console service with no API; for now it is enabled by contacting support, with manual review. Some sites do not offer this feature yet.
Why Prospects
Many teams using our API are doing the same thing: using AI to win customers abroad, writing cold emails, running outbound calls, building sales agents. A model can write every email well, but "who to write to" is often the hardest step.
OneFast API already has Web Data capabilities such as web search, map places and public company contacts. On top of that, Prospects has the team filter, verify and deliver against your brief, giving you a list of companies you can start working on, so your AI app goes from "can write" to "has someone to write to".
What you get
- Tailored: filtered by product, industry, size and target country, not a generic database export.
- Verifiable: every lead comes with the website, identity evidence and source links, so you can check it before reaching out.
- Public business contacts: only contact details the company has published, no personal private data.
- 90-day peer exclusivity: a lead is not delivered to other customers in your industry and region for 90 days.
How it works
- Contact support to get enabled (manual review).
- Submit a brief on the "Prospects" page in the console: what you sell, target regions, contact channels, how many leads.
- The team confirms the count, delivery time and price with you (offline during Alpha).
- Preview the results online and download CSV / Excel.
