What is an API Key?
Understanding API Keys and How They Work in Your Workspace
API keys are essential tools for integrating AI models, such as OpenAI and Anthropic, into your workspace. They serve as a unique identifier that authorizes your workspace to access AI services, enabling your team to leverage advanced AI capabilities within ChatNGO. Here is a breakdown of what API keys are, how they centralize AI usage and billing, and why they are a cost-effective way to provide AI access across your team.
What is an API Key?
An API key is a unique string of characters that allows your workspace to securely communicate with external AI services, such as OpenAI or Anthropic. Instead of each team member needing a separate API key, a single key is used for the entire workspace. This centralized approach simplifies AI management and billing by:
Allowing all members of the workspace to use AI through a shared key.
Tracking usage collectively, not individually, so that the workspace pays for AI usage as a whole rather than on a per-member basis.
Each provider requires a unique API key, meaning you will need one API key for OpenAI and another for Anthropic. A single API key from a provider grants access to all the models that provider offers.
Benefits of Using API Keys in Your Workspace
1. Cost-Effective AI Access
Single Payment Structure: Using one API key for the entire workspace means that you only pay for the actual AI usage rather than on a per-user basis. This is particularly cost-effective for larger teams.
No Per-Member Charges: The whole team can access AI without needing to set up individual accounts or keys, reducing administrative work and potential fees.
2. Centralized Usage Tracking
Monitor AI Usage: Since all usage is routed through the workspace’s API key, you can easily track the total amount of AI being used. This helps in budgeting and adjusting based on actual needs.
Set Usage Limits: You can set limits to avoid exceeding your budget, ensuring that sudden increases in usage do not lead to unexpected costs.
Usage Tiers and Rate Limits
When using AI services, your workspace's access to models is managed by usage tiers, each with specific rate limits. These tiers determine the amount of AI processing you can access, such as the number of requests or tokens allowed per minute or day.
Rate Limits: Each tier has a cap on the number of requests per minute, tokens per minute, or tokens per day. Exceeding these limits may result in request throttling or "429 Error" messages indicating too many requests.
Tiers Vary by Provider: OpenAI and Anthropic offer multiple usage tiers, with higher tiers providing more generous limits. Access to these higher tiers may require a minimum period of usage or reaching specific spending thresholds.
Usage Limits: Usage limits are determined by the AI model providers (such as OpenAI and Anthropic) and are not controlled or set by ChatNGO.
Tier: The selected tier affects only the rate limits (such as requests per minute) and does not impact the cost per token used.

Key Considerations for Managing API Keys
1. Monitor Billing Regularly
Track Usage: Use the dashboards provided by OpenAI and Anthropic to keep an eye on how much AI is being used in your workspace.
Set Limits: To prevent unexpected costs, consider setting usage limits on API calls.
2. Check Model Costs
Model Cost Variations: Different models (e.g., GPT-4o, Claude 3.5 Sonnet) have different costs depending on complexity and data processed. Simpler tasks can often be handled by more cost-efficient models, while complex analysis may require more advanced, higher-cost models.
Enable Models Strategically: Avoid enabling all models if some are cost-prohibitive or unnecessary. Admins can educate users on which model is best for specific tasks.
3. Configure Billing and Payment Plans
Both OpenAI and Anthropic offer flexible pay-per-usage billing options. Be sure to configure these settings based on your workspace’s needs to optimize your budget.
