How does ReliAPI prevent duplicate charges?

ReliAPI uses idempotency keys to ensure the same request is only charged once, even if users click twice or retries happen. Same request with same key = only one charge.

How much can I save on LLM API costs with ReliAPI?

ReliAPI can reduce LLM API costs by 50-80% through intelligent caching. Repeated questions don't trigger new API calls - same question = instant response, no API call, no charge.

Does ReliAPI support OpenAI, Anthropic, and Mistral APIs?

Yes, ReliAPI works seamlessly with OpenAI (GPT-4, GPT-4 Turbo, GPT-3.5), Anthropic (Claude 3 Opus, Sonnet, Haiku), and Mistral (Large, Medium, Small) APIs. No configuration needed for LLM providers.

What is a circuit breaker and how does ReliAPI use it?

A circuit breaker automatically stops calling failing services to prevent cascading failures. ReliAPI's circuit breaker detects failures and auto-recovers when services come back online, protecting your application from API outages.

How does ReliAPI handle retry logic?

ReliAPI implements automatic retries with exponential backoff and jitter. It respects Retry-After headers from upstream APIs and handles temporary failures gracefully, eliminating the need for manual retry logic.

Can I set budget limits with ReliAPI?

Yes, ReliAPI supports both hard and soft cost caps for LLM APIs. Hard caps automatically reject expensive requests before they execute, while soft caps reduce max_tokens to stay within budget. Perfect for preventing surprise bills.
