Company Discovery

Use the Data API to discover matching companies from external sources.

Last updated: June 16, 2026

Summary

Company discovery contains the POST /v2/prospect/companies endpoint and its interactive playground.Use POST /v2/prospect/companies to discover matching companies from external sources using either a freeform search query or structured filters.For example, you can send a request like "find manufacturing companies in Tokyo with more than 200 employees" and get back a ranked list of matching company candidates.

Authentication

  • Send your Developer API key as Authorization: Bearer <api_key>
  • Use Full access because this endpoint uses POST

When to use it

Use company discovery when you want to:
  • discover new company candidates that match a target profile
  • pass a natural-language request directly into the API
  • filter by location, industry, and employee-count range in the same request
Main request fields:
  • query: freeform search criteria
  • location: city, region, or country
  • industry: industry label or vertical
  • min_employee_count and max_employee_count: employee range filters
  • limit: number of results to return, from 1 to 20
  • sources: external providers to request; defaults to ["exa"]

Coverage

  • v2 supports company prospecting
  • either query or at least one structured filter is required
  • responses include parsed_filters so you can inspect how the request was interpreted
  • this is a read-oriented API: it returns candidates but does not create or update Sanka company records

Send the request

cURL
curl -X POST "https://api.sanka.com/v2/prospect/companies" \
  -H "Authorization: Bearer <api_key>" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "find manufacturing companies in Tokyo with more than 200 employees",
    "limit": 10,
    "sources": ["exa"]
  }'
You can also skip the freeform query and use structured filters only:
JSON
{
  "location": "Tokyo",
  "industry": "manufacturing",
  "min_employee_count": 200,
  "limit": 10
}
Use the interactive playground in the OpenAPI reference on this page to test the same request.

Review the response

The response includes:
  • query: the search text used for the run
  • parsed_filters: the normalized location, industry, and employee filters
  • results: the discovered company candidates
  • count: the number of returned candidates
  • provider_meta: source usage and extraction metadata
Each result can include company name, URL, domain, industry, employee count, description, source URLs, and match_reasons.

Supported sources

  • v2 executes prospect discovery through exa
  • you can pass multiple provider names in sources, but unsupported names are not executed
  • if you include a name such as google_maps, it is reported under provider_meta.unsupported_sources
  • check provider_meta.requested_sources, provider_meta.supported_sources, and provider_meta.unsupported_sources to see what happened in a run
