Preview. Part of the Migration API — in active design and not yet generally available. Endpoints and payloads may change. See the overview.
All Vern API requests authenticate with an API key passed in the x-api-key header. 
curl https://app.vern.so/api/v1/companies \
  -H "x-api-key: YOUR_API_KEY"

​
Get a key

Sign in to app.vern.so and go to Settings → API keys. Click New key and copy it — Vern doesn’t show it again after creation. For details on generating, rotating, and revoking keys, see API keys.

​
What can go wrong

  • 401 Unauthorized — key is missing, malformed, or revoked.
  • 429 Too many requests — you’ve hit the rate limit. Back off and retry.

​
Security

  • Never put your key in client-side code. Vern’s API is designed to be called from your backend.
  • Use environment variables, not hardcoded strings.
  • Rotate keys periodically and immediately if you suspect leakage.
Webhook payloads are signed separately via Svix — see Webhooks for signature verification.
