CLI auth endpoints

If you’re not building a client, use slideless auth ... — it wraps these endpoints, handles --json, and saves the resulting cko_ key as a local profile.

Overview

Endpoint	Purpose	Auth
`POST /cliRequestSignupOtp`	Email a signup OTP to a brand-new email	Public (no Authorization header)
`POST /cliCompleteSignup`	Verify the OTP, create user + org + API key	Public
`POST /cliRequestLoginOtp`	Email a login OTP to an existing account	Public
`POST /cliCompleteLogin`	Verify the OTP, mint a fresh API key	Public

Base URL: https://europe-west1-slideless-ai.cloudfunctions.net/ All four endpoints return the same discriminated-union shape:

{ "success": true,  "data": { ... } }
{ "success": false, "error": { "code": "...", "message": "...", "nextAction": "...", "details": { ... } } }

HTTP status mirrors the error category: 400 for validation, 404 for missing user/code, 409 for state conflicts, 410 for expired code, 429 for rate limits, 500 for internals.

Common rules

Resend cooldown: the -request endpoints reject with OTP_RESEND_COOLDOWN if called twice within 30 seconds for the same email.
Abuse caps: 20 requests per email per hour, 60 per IP per hour, across both signup and login.
Code lifetime: 10 minutes. 5 bad attempts locks the code out.
Purpose isolation: a code issued for signup cannot be consumed by cliCompleteLogin (and vice versa) — returns OTP_PURPOSE_MISMATCH.

POST /cliRequestSignupOtp

When to use

Brand-new user; no Slideless account yet. Pre-flight check: if a Firebase Auth user already exists for the email and has ≥1 organization, the request returns USER_ALREADY_HAS_ORGANIZATION — the client should switch to /cliRequestLoginOtp.

Endpoint

POST https://europe-west1-slideless-ai.cloudfunctions.net/cliRequestSignupOtp

Request body

{ "email": "you@example.com" }

Field	Type	Required	Notes
`email`	string	yes	Lowercased server-side for rate-limit keying

Response (200)

{
  "success": true,
  "data": {
    "email": "you@example.com",
    "expiresInSeconds": 600
  }
}

Examples

curl -sS -X POST \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com"}' \
  https://europe-west1-slideless-ai.cloudfunctions.net/cliRequestSignupOtp

const res = await fetch(
  'https://europe-west1-slideless-ai.cloudfunctions.net/cliRequestSignupOtp',
  {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ email: 'you@example.com' }),
  },
);
const body = await res.json();
if (!body.success) throw new Error(body.error.message);

Errors

Status	Code	Meaning
400	`EMAIL_REQUIRED` / `EMAIL_INVALID`	Missing or malformed `email`
429	`OTP_RESEND_COOLDOWN`	Called again within 30 s; `details.retryInSeconds` set
429	`EMAIL_RATE_LIMITED` / `IP_RATE_LIMITED`	Abuse caps hit
409	`USER_ALREADY_HAS_ORGANIZATION`	Switch to `/cliRequestLoginOtp`

POST /cliCompleteSignup

When to use

Second half of signup. Consumes the emailed code, creates the Firebase Auth user (if missing), creates a users/{uid} doc, creates a single-owner organization, optionally uploads the logo to GCS, mints a cko_ API key with full presentation scopes, and returns the raw key.

Endpoint

POST https://europe-west1-slideless-ai.cloudfunctions.net/cliCompleteSignup

Request body

{
  "email": "you@example.com",
  "code": "123456",
  "user": {
    "firstName": "Alex",
    "lastName": "Morgan"
  },
  "company": {
    "name": "Acme",
    "description": "We make widgets",
    "brandPrimary": "#0a0a0a",
    "brandSecondary": "#888888",
    "brandAccent": "#e53935",
    "tone": "Pragmatic, concise, a bit dry"
  },
  "logo": {
    "data": "<base64-encoded bytes>",
    "contentType": "image/png"
  },
  "apiKey": {
    "name": "CI",
    "expiresInDays": 30
  }
}

Field	Required	Notes
`email`, `code`	yes	6-digit numeric code from the OTP email
`user.firstName`	yes	Stored as the user’s display name and used in onboarding emails. Max 60 chars
`user.lastName`	no	Appended to display name when present. Max 60 chars
`company.name`	no	Defaults to `"<user.firstName>'s workspace"`. Max 100 chars
`company.description`, `company.tone`	no	Free text
`company.brandPrimary` / `brandSecondary` / `brandAccent`	no	6-digit hex, with or without leading `#`
`logo.data`	no	Base64-encoded bytes, max 2 MB decoded
`logo.contentType`	no	`image/png`, `image/jpeg`, `image/webp`, `image/svg+xml`
`apiKey.name`	no	Defaults to `"CLI default key"`
`apiKey.expiresInDays`	no	1–365; omit for no expiration

Response (200)

{
  "success": true,
  "data": {
    "organizationId": "4XYwOrZ8QMyyELm1310R",
    "organizationName": "Acme",
    "apiKey": {
      "keyId": "019da6...",
      "raw": "cko_O_Q8...",
      "keyPrefix": "cko_O_Q8",
      "name": "CLI default key",
      "scopes": ["presentations:write", "presentations:read"],
      "createdAt": "2026-04-19T14:21:03.000Z"
    },
    "isNewUser": true
  }
}

apiKey.raw is only returned in this single response — the server stores a SHA-256 hash.

Errors

Status	Code	Meaning
400	`EMAIL_REQUIRED` / `OTP_INVALID`	Missing/malformed inputs
400	`USER_FIRST_NAME_REQUIRED`	Missing `user.firstName`
400	`USER_NAME_TOO_LONG`	`user.firstName` or `user.lastName` over 60 chars
400	`COMPANY_NAME_TOO_LONG` / `BRAND_COLOR_INVALID`	Optional fields failed validation
400	`LOGO_TOO_LARGE` / `LOGO_INVALID_FORMAT` / `LOGO_DECODE_FAILED`	Logo rejected
400	`INVALID_EXPIRES_IN_DAYS`	`apiKey.expiresInDays` outside 1–365
404	`OTP_NOT_FOUND`	No pending code; run `/cliRequestSignupOtp` first
410	`OTP_EXPIRED`	> 10 min old
409	`OTP_ALREADY_USED` / `OTP_PURPOSE_MISMATCH`	Request a new signup code
429	`OTP_LOCKED_OUT`	5 failed attempts; request a fresh code
409	`USER_ALREADY_HAS_ORGANIZATION`	Happened in the race window; switch to login
500	`INTERNAL`	Retry; contact support if persistent

POST /cliRequestLoginOtp

When to use

Existing user on a new machine (or with a revoked key). Pre-flight check: if the email has no Firebase Auth user, returns USER_NOT_FOUND; if it exists but has no organization, returns USER_HAS_NO_ORGANIZATION. Both push the client back to /cliRequestSignupOtp.

Endpoint

POST https://europe-west1-slideless-ai.cloudfunctions.net/cliRequestLoginOtp

Request body

{ "email": "you@example.com" }

Response (200)

Same shape as /cliRequestSignupOtp:

{
  "success": true,
  "data": { "email": "you@example.com", "expiresInSeconds": 600 }
}

Errors

Status	Code	Meaning
400	`EMAIL_REQUIRED` / `EMAIL_INVALID`	Missing or malformed
429	`OTP_RESEND_COOLDOWN` / `EMAIL_RATE_LIMITED` / `IP_RATE_LIMITED`	Rate limits
404	`USER_NOT_FOUND`	No account; switch to signup
409	`USER_HAS_NO_ORGANIZATION`	Switch to signup

POST /cliCompleteLogin

When to use

Consume a login OTP and mint a fresh cko_ key for the account’s existing organization.

Endpoint

POST https://europe-west1-slideless-ai.cloudfunctions.net/cliCompleteLogin

Request body

{
  "email": "you@example.com",
  "code": "123456",
  "apiKey": { "name": "CI", "expiresInDays": 30 }
}

apiKey is optional (same defaults as /cliCompleteSignup).

Response (200)

{
  "success": true,
  "data": {
    "organizationId": "4XYwOrZ8QMyyELm1310R",
    "organizationName": "Acme",
    "apiKey": {
      "keyId": "019db0...",
      "raw": "cko_9v...",
      "keyPrefix": "cko_9v4k",
      "name": "CLI default key",
      "scopes": ["presentations:write", "presentations:read"],
      "createdAt": "2026-04-19T16:00:00.000Z"
    }
  }
}

Each successful call mints a new key. Previous keys stay valid until revoked from the dashboard.

Errors

Status	Code	Meaning
400	`EMAIL_REQUIRED` / `OTP_INVALID`	Missing/malformed inputs
400	`INVALID_EXPIRES_IN_DAYS`	`apiKey.expiresInDays` outside 1–365
404	`OTP_NOT_FOUND`	Run `/cliRequestLoginOtp` first
410	`OTP_EXPIRED`	> 10 min old
409	`OTP_ALREADY_USED` / `OTP_PURPOSE_MISMATCH`	Request a new login code
429	`OTP_LOCKED_OUT` / `MAX_API_KEYS_REACHED`	Revoke unused keys from the dashboard
409	`USER_HAS_NO_ORGANIZATION`	Happens if org was deleted between request + complete
500	`INTERNAL`	Retry

Agent recipe

For a script or Claude Code skill: run the signup path optimistically; if the server says the user already has an organization, retry via login. This handles every case in two or three HTTP calls.

# Pseudo-code
RESP=$(curl -sS ... /cliRequestSignupOtp)
CODE=$(echo $RESP | jq -r 'select(.success == false) | .error.code')
if [ "$CODE" = "USER_ALREADY_HAS_ORGANIZATION" ]; then
  curl -sS ... /cliRequestLoginOtp
  # then cliCompleteLogin
else
  # ask user for the 6-digit code, then cliCompleteSignup
fi

The setup-slideless marketplace skill encodes this logic.
