Authentication

API Key Authentication

All each::labs APIs use API key authentication via the X-API-Key header.

curl https://api.eachlabs.ai/v1/models \
  -H "X-API-Key: YOUR_API_KEY"

Your API key grants full access to your account. Never expose it in client-side code, public repositories, or logs.

Include the X-API-Key header in every request:

curl https://api.eachlabs.ai/v1/models \
  -H "X-API-Key: YOUR_API_KEY"

import requests

headers = {"X-API-Key": "YOUR_API_KEY"}
response = requests.get("https://api.eachlabs.ai/v1/models", headers=headers)

const response = await fetch("https://api.eachlabs.ai/v1/models", {
  headers: { "X-API-Key": "YOUR_API_KEY" },
});

Product	Header	Base URL	Status
each::api	`X-API-Key`	`https://api.eachlabs.ai`	Canonical api-service host
each::workflows	`X-API-Key`	`https://workflows.eachlabs.run/api/v1`	Workflows-engine host; planned to route through `https://api.eachlabs.ai`
each::sense	`X-API-Key`	`https://eachsense-agent.core.eachlabs.run`	Current each::sense host

Some endpoints like GET /v1/models (listing models) do not require authentication. Check individual endpoint documentation for details.

If your API key is missing or invalid, you’ll receive a 401 response:

{
  "error": "Invalid or missing API key"
}

Issue	Solution
Missing header	Add `X-API-Key: YOUR_KEY` to your request headers
Invalid key	Verify the key in your dashboard
Expired key	Generate a new API key
Wrong product URL	Ensure you’re using the correct base URL for the product
