Authentication

Every request authenticates with an API key tied to your workspace.

Passing the key

Use a bearer token (recommended — matches the SDK and the OpenAI/Anthropic convention):

curl https://www.artemise.live/api/v1/signals \
  -H "Authorization: Bearer ns_live_..."

The x-api-key: ns_live_... header is also accepted.

Getting a key

Two ways:

• Dashboard — Settings → API → Create key. The plaintext is shown once.
• SDK login — await Artemise.login() or npx artemise login runs a browser approval and provisions a key for you. See Connect the SDK.

Subscription requirement

API access is part of every paid plan. Without an active subscription:

• creating a key returns 402
• every /api/v1 call returns 403
• SDK login approval is blocked in the browser

Subscribe in Settings → Billing (design partners: your promo code applies at checkout).

Key security

• Keys are 192-bit random secrets; only a SHA-256 hash is stored
• The plaintext is shown exactly once at creation
• Revoke instantly from Settings → API — revocation takes effect on the next request
• Never commit keys; use the ARTEMISE_API_KEY environment variable
