Authentication

All endpoints require an API key. Include it on every request as an X-API-Key header.

curl -X POST 'https://api.govfiles.dev/v2/companies/search' \
  -H 'Content-Type: application/json' \
  -H "X-API-Key: $GOVFILES_API_KEY" \
  -d '{"q":"acme","jurisdictions":"all","limit":10}'

To generate an API key, sign up at govfiles.dev/signup and create an account. Requests without a key or with an invalid key return 401 Unauthorized.
