Build on company data that shows its sources
A JSON API for companies, contract awards, grants, subcontracts and signals. Every field comes with where it came from, how it is known and when it was collected.
Endpoints
The read endpoints available today. Responses are JSON; amounts are US dollars.
| Endpoint | Parameters | Returns |
|---|---|---|
GET/v1/companies | q, agency, naics, state, limit (1 to 100) | Companies with award counts and totals, best match first |
GET/v1/companies/{id} | None | One company: every field with its source, quality and dates, its contract awards, grants, teaming partners (primes and subcontractors) and signals |
GET/v1/signals | limit | The newest signals, each with the record it came from |
GET/v1/stats/directory | None | Company counts by state, industry code and agency |
GET/v1/stats/awards-by-agency | None | Award counts and amounts for the top agencies |
Every field, with its source
Each field on a company carries its provenance, so your systems can show it, filter on it, or drop what is only estimated. Quality is one of verified, reported, inferred or stale. How a fact is known.

}Coming next
The API follows the same rules as the app: the same plan limits, the same opt-outs, and only the uses each source allows.
- API keys and usage
- Named keys with scopes, shown once, and usage by day.
- Webhooks
- signal.created, list.changed, credits.low and record.removed, signed so you can check they came from us.
- People and contacts
- When contacts launch, under the same rules as the app: opted-out people never appear.
- Bulk data feeds
- Licensed files for data and risk teams, where each source's terms allow it.
