Getting Started
Authentication
Magic links, API keys, rate limits, and BYOK architecture.
Magic Link Sign-In
MetaMemory uses passwordless authentication via magic links:
POST https://api.metamemory.tech/v1/auth/magic-link
{ "email": "you@company.com" }Check your email and click the link. You'll be redirected to the dashboard with a fresh API key.
Note: Each sign-in rotates your API key. The previous key is immediately invalidated.
API Key Format
API keys follow the format mm_live_<32 hex chars>. Include it in every request:
Authorization: Bearer mm_live_your_key_hereKeys are SHA-256 hashed before storage — MetaMemory never stores your plaintext key.
Rate Limits
| Tier | Requests/min | Daily Memories | Monthly Queries |
|---|---|---|---|
| Free | 120 | 5,000 | 50,000 |
| Pro | 600 | 100,000 | 1,000,000 |
| Enterprise | 3,000 | Unlimited | Unlimited |
Rate limit headers are included in every response:
X-RateLimit-Limit— your tier's limitX-RateLimit-Remaining— remaining requestsX-RateLimit-Reset— when the window resets
Tenant Isolation
Every request is scoped to your tenant. Your memories, conversations, and episodes are completely isolated — no other tenant can access your data. Vector search is namespace-partitioned and all database queries filter by tenantId.
