API Key ManagementLink to section

API keys authenticate your workloads against ling-1t.ai. Keys are scoped to the owning account and track usage for billing and audit logs.

Create a KeyLink to section

1. Sign in at https://ling-1t.ai/dashboard.
2. In the API Keys card, select Create API key.
3. Provide a label (e.g., “production-backend”).
4. Copy the generated value immediately—keys are only shown once.

The dashboard displays the prefix and last eight characters for reference. Each account can hold up to MAX_API_KEYS_PER_USER active keys (defaults to 10; configurable via environment variable).

• Use the Revoke action in the dashboard to immediately invalidate a key. Revocation cannot be undone.
• Update your applications to use a new key before revoking the old one to prevent downtime.

Keys are hashed at rest and linked to billing records. Each request updates the key’s last_used_at field for audit trails.
