Ideogram Enterprise RBAC

Overview

Implement team-based access control for Ideogram's API. Since Ideogram uses a single API key per account with no built-in roles or scopes, enterprise access control must be implemented at the application layer: separate API keys per team, proxy-based content filtering, per-team budget limits, and usage tracking.

Instructions

Step 1: Team Configuration

interface TeamConfig {
  name: string;
  apiKey: string;             // Separate Ideogram API key per team
  dailyBudgetUSD: number;
  allowedStyles: string[];
  allowedModels: string[];
  maxConcurrency: number;
  contentPolicy: "strict" | "moderate" | "permissive";
}

const TEAM_CONFIGS: Record<string, TeamConfig> = {
  marketing: {
    name: "Marketing",
    apiKey: process.env.IDEOGRAM_KEY_MARKETING!,
    dailyBudgetUSD: 20,
    allowedStyles: ["DESIGN", "REALISTIC"],
    allowedModels: ["V_2", "V_2_TURBO"],
    maxConcurrency: 5,
    contentPolicy: "strict",
  },
  product: {
    name: "Product Design",
    apiKey: process.env.IDEOGRAM_KEY_PRODUCT!,
    dailyBudgetUSD: 50,
    allowedStyles: ["DESIGN", "REALISTIC", "RENDER_3D", "GENERAL"],
    allowedModels: ["V_2", "V_2_TURBO"],
    maxConcurrency: 8,
    contentPolicy: "moderate",
  },
  social: {
    name: "Social Media",
    apiKey: process.env.IDEOGRAM_KEY_SOCIAL!,
    dailyBudgetUSD: 10,
    allowedStyles: ["DESIGN", "ANIME", "GENERAL"],
    allowedModels: ["V_2_TURBO"],
    maxConcurrency: 3,
    contentPolicy: "strict",
  },
};

Step 2: Content Policy Enforcement

interface ContentCheck {
  allowed: boolean;
  reason?: string;
}

const BLOCKED_TERMS: Record<string, RegExp[]> = {
  strict: [
    /\b(competitor|trademark|brand)\b/i,
    /\b(violent|weapon|blood|gore)\b/i,
    /\b(nsfw|nude|explicit)\b/i,
  ],
  moderate: [
    /\b(nsfw|nude|explicit)\b/i,
  ],
  permissive: [],
};

function checkContentPolicy(prompt: string, policy: "strict" | "moderate" | "permissive"): ContentCheck {
  const patterns = BLOCKED_TERMS[policy] ?? [];
  for (const pattern of patterns) {
    if (pattern.test(prompt)) {
      return { allowed: false, reason: `Blocked by ${policy} policy: ${pattern.source}` };
    }
  }
  if (prompt.length > 10000) {
    return { allowed: false, reason: "Prompt exceeds 10,000 character limit" };
  }
  return { allowed: true };
}

Step 3: Budget Enforcer

const dailySpend = new Map<string, number>();

function trackSpend(teamId: string, model: string, numImages: number = 1) {
  const costPerImage: Record<string, number> = {
    V_2_TURBO: 0.05, V_2: 0.08, V_2A_TURBO: 0.025, V_2A: 0.04,
  };

  const cost = (costPerImage[model] ?? 0.08) * numImages;
  const current = dailySpend.get(teamId) ?? 0;
  dailySpend.set(teamId, current + cost);

  return current + cost;
}

function checkBudget(teamId: string): { allowed: boolean; remaining: number } {
  const config = TEAM_CONFIGS[teamId];
  if (!config) return { allowed: false, remaining: 0 };

  const spent = dailySpend.get(teamId) ?? 0;
  const remaining = config.dailyBudgetUSD - spent;

  return { allowed: remaining > 0, remaining };
}

// Reset daily at midnight
setInterval(() => {
  dailySpend.clear();
  console.log("Daily budget counters reset");
}, 86400000);

Step 4: Team-Scoped Proxy

async function teamGenerate(
  teamId: string,
  prompt: string,
  options: { style_type?: string; model?: string; aspect_ratio?: string } = {}
) {
  const config = TEAM_CONFIGS[teamId];
  if (!config) throw new Error(`Unknown team: ${teamId}`);

  // Check content policy
  const contentCheck = checkContentPolicy(prompt, config.contentPolicy);
  if (!contentCheck.allowed) {
    throw new Error(`Content blocked: ${contentCheck.reason}`);
  }

  // Check style permission
  const style = options.style_type ?? "AUTO";
  if (style !== "AUTO" && !config.allowedStyles.includes(style)) {
    throw new Error(`Style ${style} not allowed for team ${config.name}`);
  }

  // Check model permission
  const model = options.model ?? config.allowedModels[0];
  if (!config.allowedModels.includes(model)) {
    throw new Error(`Model ${model} not allowed for team ${config.name}`);
  }

  // Check budget
  const budget = checkBudget(teamId);
  if (!budget.allowed) {
    throw new Error(`Daily budget exceeded for team ${config.name}. Remaining: $${budget.remaining.toFixed(2)}`);
  }

  // Generate using team's API key
  const response = await fetch("https://api.ideogram.ai/generate", {
    method: "POST",
    headers: {
      "Api-Key": config.apiKey,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      image_request: {
        prompt,
        model,
        style_type: style,
        aspect_ratio: options.aspect_ratio ?? "ASPECT_1_1",
        magic_prompt_option: "AUTO",
      },
    }),
  });

  if (!response.ok) throw new Error(`Ideogram API error: ${response.status}`);

  // Track spending
  trackSpend(teamId, model);

  return response.json();
}

Step 5: Usage Dashboard Data

function teamUsageReport() {
  const report = [];
  for (const [teamId, config] of Object.entries(TEAM_CONFIGS)) {
    const spent = dailySpend.get(teamId) ?? 0;
    report.push({
      team: config.name,
      dailyBudget: config.dailyBudgetUSD,
      spent: spent.toFixed(2),
      remaining: (config.dailyBudgetUSD - spent).toFixed(2),
      utilization: `${((spent / config.dailyBudgetUSD) * 100).toFixed(0)}%`,
    });
  }
  console.table(report);
  return report;
}

Step 6: Key Rotation Schedule

Quarterly key rotation process:
1. Create new API key in Ideogram dashboard for each team
2. Update secrets in your secret manager
3. Deploy with new keys to staging, verify
4. Deploy to production
5. Monitor for 48 hours
6. Delete old keys from Ideogram dashboard

Error Handling

Output

• Per-team API key isolation
• Content policy enforcement (strict/moderate/permissive)
• Daily budget tracking with automatic enforcement
• Team-scoped generation proxy
• Usage dashboard data for reporting
