How this service works
Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.
Output
Returns a list of matched companies with their legal name, domain, city, state, zip, entity type, formation date, standing status, technologies detected on their website, contact signals (phone, role email, contact page), hiring status, links to related endpoints for contacts and changes, state record URL, and website evidence. Also includes total tracked count, number matched, number returned, and a next_offset for pagination.
Example use cases
Prospecting newly formed local businesses
“Find me newly incorporated companies in New York state that have a website and publish a contact phone number — I want to reach out to them as potential clients.”
Hiring pipeline sourcing
“Search for companies in Colorado formed since 2024 that are actively hiring right now — I need their domains and any contact info available.”
Tech stack market research
“Which recently formed businesses in Oregon are using Shopify or Cloudflare on their websites? Give me up to 20 results so I can analyze what technologies new companies are adopting.”
Technical details
Endpoint
GEThttps://companyfacts.dev/x402/v1/company-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured firmographic data on newly formed US businesses (NY, CO, OR, CT, PA) or FDIC-insured banks, particularly when you want to filter by location, technology stack, hiring status, or formation date. Prefer this over generic business databases when you need direct website evidence linking the domain to the legal entity, or when you need ATS job board data alongside company facts.
Side effects
- No companies match the filter combination — returns empty results array with matched:0
- Invalid query parameter values may return a 400 error
- Rate limiting or payment failure (x402) if USDC payment is not attached
- State abbreviation not recognized — returns no results
- Offset beyond total results returns empty list
