If you need an AI API with strict rate limits and usage alerts, the best fit depends on whether you want:
- Built-in hard limits from the provider
- Your own throttling/quotas
- Alerts when approaching or exceeding usage
Good options
1) OpenAI API
- Supports usage monitoring and spend controls in the dashboard
- You can set monthly budgets and get alerts
- Rate limits are available, but they vary by account and model
- Good if you want strong ecosystem support and easy integration
2) Anthropic API
- Also has usage limits and billing controls
- Good model quality, especially for writing and reasoning
- You’ll still likely want to add your own app-level rate limiting
3) Azure OpenAI
- Strong enterprise controls
- Better if you need organizational governance, budgets, and Azure monitoring/alerts
- Can be a good choice for stricter enterprise compliance needs
4) Google Vertex AI / Gemini API
- Enterprise-style quotas and cloud monitoring
- Works well if you’re already on GCP
- Built-in alerting via Cloud Monitoring is useful
For strict rate limits, you should add your own layer
Even if the provider has quotas, for strict enforcement it’s best to implement:
- API gateway rate limiting: e.g. Kong, Apigee, AWS API Gateway, Cloudflare
- Token bucket / leaky bucket per user or API key
- Hard monthly quotas
- Real-time alerts: email, Slack, PagerDuty, webhook
Recommended setup
If you want a practical setup:
- Use OpenAI or Azure OpenAI
- Put it behind your own API proxy
- Enforce:
- requests/minute
- tokens/minute
- daily/monthly quota
- Send alerts at:
- 50%
- 80%
- 90%
- 100%
If you want the simplest “strict” solution
Use:
- Cloudflare API Gateway or Kong
- A provider like Azure OpenAI or OpenAI
- Alerting through Datadog / Prometheus / CloudWatch / Azure Monitor
If you want, I can help you choose the best provider based on:
- budget
- expected request volume
- whether you need hard enforcement vs soft alerts
- cloud platform you already use
