​
Base URL

All API requests are made to: 
https://api.mnemom.ai/v1
The API is versioned at two levels:
  • URL (/v1/) — the API generation. Changes only for complete redesigns (infrequent).
  • X-Mnemom-Version: YYYY-MM-DD header — controls behavior within /v1/. Pin this for production stability.
curl https://api.mnemom.ai/v1/agents \
  -H "X-Mnemom-Api-Key: <key>" \
  -H "X-Mnemom-Version: 2026-04-13"
If you omit X-Mnemom-Version, the latest behavior is used — fine for new integrations, but production systems (including AI agents) should pin to a specific date. Every response echoes the version used: 
X-Mnemom-Version: 2026-04-13
Current version: 2026-04-13. Support window: 18 months per version. See the API Versioning guide for full details.

​
Authentication

The Mnemom API supports three authentication patterns. Pick the one that matches the caller, not the endpoint. For end-user sign-in (passkey, password + MFA, SSO), session lifecycle, and API-key rotation, see the Authentication guide. Passkeys are the default dashboard sign-in method — see Passkeys for browser support and enrollment. Browser sessions at www.mnemom.ai and app.mnemom.ai authenticate via an HttpOnly, Secure, SameSite=Lax cookie named mnemom_session, issued on sign-in by the API itself. The cookie is opaque to JavaScript — it holds an AES-256-GCM-encrypted blob of the underlying session tokens, never a raw access token. 
# Browser flow — the SPA does this transparently; you rarely call it directly.
curl -X POST https://api.mnemom.ai/v1/auth/sign-in \
  -H "Content-Type: application/json" \
  -H "Origin: https://www.mnemom.ai" \
  --cookie-jar cookies.txt \
  -d '{"email":"you@example.com","password":"..."}'

# Subsequent authenticated requests attach the cookie.
curl https://api.mnemom.ai/v1/agents \
  --cookie cookies.txt
The gateway auto-refreshes an expired access token server-side and rotates the cookie in the response. Passkey (WebAuthn / FIDO2) sign-in endpoints live at /v1/auth/passkey/* and return the same session cookie; MFA step-up and SSO are carried through /v1/auth/mfa/* and /v1/auth/sso/*. Sensitive operations require AAL2 step-up — a fresh user-verification gesture within the session’s AAL2 window; see the Authentication guide for the list of protected actions. This is the only auth pattern where Access-Control-Allow-Credentials: true matters — fetch() calls from the SPA must include credentials: "include".

​
Bearer token (CLI)

The Mnemom CLI and anything mimicking it use the classic Authorization: Bearer <token> header. The CLI obtains its token via a one-time browser → localhost handoff at login time (exchanged through POST /v1/auth/cli-exchange, which requires an already-authenticated session cookie); the raw token never leaves the CLI’s local auth file after that. 
curl https://api.mnemom.ai/v1/agents \
  -H "Authorization: Bearer <token>"
How to get a Bearer token outside the CLI: run mnemom login and read ~/.mnemom/auth.json. Generating your own Bearer tokens from scratch is not supported — use an API key (below) for programmatic access.

​
API key

For server-to-server and enterprise fleet management, authenticate with an API key: 
curl https://api.mnemom.ai/v1/agents \
  -H "X-Mnemom-Api-Key: <key>"
How to get an API key: Generate one from the Mnemom Dashboard under Settings > API Keys. API keys are scoped to your user account (or organization) and can be rotated at any time. Creating or rotating a key requires AAL2 step-up; see Authentication — API keys for the rotation procedure. API keys are accepted on all agent management endpoints — agent CRUD, card and policy management, integrity operations, webhooks, enforcement, reviews, and deployments. This lets enterprise customers manage agent fleets programmatically without a user session. The only endpoints that require an end-user identity (cookie or Bearer) are account self-service operations: GET /v1/auth/me, DELETE /v1/auth/delete-account, POST /v1/agents/:id/link, and billing management.
API keys are hashed on our servers and cannot be retrieved after creation. Store your key securely when it is first displayed.

​
Error format

All error responses return a JSON body with a human-readable error field: 
{
  "error": "Human-readable error message"
}

​
Common HTTP status codes

Status CodeMeaning
400Bad Request — The request body is malformed or missing required fields.
401Unauthorized — Missing or invalid authentication credentials.
403Forbidden — Valid credentials but insufficient permissions for the requested resource.
404Not Found — The requested resource does not exist.
429Too Many Requests — Rate limit exceeded. Retry after the duration specified in the Retry-After header.
500Internal Server Error — Something went wrong on our end. Contact support if the issue persists.

​
Rate limits

API requests are rate-limited across three tiers, evaluated in order:
TierScopeDefault LimitConfigurable
Per-IPClient IP address100 requests/minuteNo
Per-agentAgent hash (API key identity)100 requests/minuteYes (per-org)
Per-orgBilling account1,000 requests/minuteYes (per-org)
Enterprise organizations can request custom per-org and per-agent limits via their account settings or by contacting support.

​
Rate limit response

When any tier is exceeded, the API returns HTTP 429 with these headers:
HeaderDescription
Retry-AfterSeconds to wait before retrying
X-RateLimit-LimitMaximum requests allowed in the window
X-RateLimit-RemainingRequests remaining (always 0 on a 429)
X-RateLimit-ResetUnix timestamp when the window resets
{
  "error": "Rate limit exceeded",
  "type": "rate_limit_error",
  "tier": "ip",
  "limit": 100,
  "retry_after": 42
}
The tier field indicates which limit was hit (ip, agent, or org). Rate limit windows are 1 minute.

​
Versioning

The API is versioned via the URL path (/v1). When breaking changes are introduced, a new version will be released under a new path (e.g., /v2). Non-breaking changes (new optional fields, new endpoints) are added to the current version without a version bump. We will provide advance notice and a migration guide before deprecating any API version.
