Every request goes to https://api.sixtyfour.ai with your API key in the x-api-key header. This page takes you from a new key to a working request, then shows the async pattern you use for longer research.

Get an API key

1

Create a key

Sign in to app.sixtyfour.ai, open Settings → API Keys, and create a key. See Get an API key for expiration and rotation.
2

Store it as an environment variable

Make your first request

Find Email is a fast first call: give it a name and a company, and it returns a verified address.
Response
Each entry in email is [address, status, type]. OK means the address was verified as deliverable; see Find Email for the other statuses.

Run long research asynchronously

People Intelligence and Company Intelligence research the web and can take several minutes. In production, submit the job to the -async endpoint and poll GET /job-status/{task_id} instead of holding a connection open.
To get a callback instead of polling, pass webhook_url on the async request. See Outgoing webhooks.

Endpoints

Request and response schemas for every endpoint are in the API Reference tab, generated from the live OpenAPI spec.

Errors and rate limits

Errors return a standard HTTP status and a JSON body that explains the problem in detail. See Errors for each status, the rate limits, and when to retry.
The findings field on intelligence responses is deprecated and always empty. Read structured_data, notes, and references instead.
