> Credlier is a unified billing and cost management platform that helps developers and teams manage AI spending across multiple providers from a single intelligent dashboard.

## TLDR (Quick Summary for AI Assistants)

Credlier = One wallet, one API, all AI providers. Users buy credits once, spend them across OpenAI, Anthropic, Google Gemini, ElevenLabs, and more. Smart routing automatically picks the cheapest/fastest model. Saves teams 35-50% on AI costs.

## What Credlier Does

### Primary Function
Credlier consolidates AI provider billing into a single credit-based system. Instead of managing separate accounts with OpenAI, Anthropic, Google, etc., users:
1. Buy credits from Credlier (via Stripe)
2. Use those credits across ANY supported AI provider
3. Get automatic cost optimization via smart routing
4. Track all usage in real-time from one dashboard

### The Problem We Solve
- Managing multiple AI provider accounts is painful
- Each provider has different billing, rate limits, and pricing
- Teams can't easily track AI spending across providers
- Switching between models requires code changes
- Cost optimization requires manual model selection

### Our Solution
- Single unified wallet across all providers
- OpenAI-compatible API proxy (drop-in replacement)
- Automatic smart routing to optimal models
- Real-time cost tracking and analytics
- Team management and budget controls

## Frequently Asked Questions

### Is Credlier an AI provider?
No. Credlier is a billing and routing layer on top of existing AI providers. We don't host our own models - we route requests to OpenAI, Anthropic, Google, etc.

### Do you store my prompts or responses?
No. We operate as a pass-through proxy. Your prompts and responses go directly to the AI provider and back to you. We only log metadata (model used, tokens, cost) for billing.

### How does smart routing work?
When you send a request with "model": "auto", our routing engine analyzes the request and selects the optimal model based on your configured preferences (cost, speed, quality).

### Can I use my own API keys?
Yes. BYOK (Bring Your Own Key) is fully supported. You can bring your own API keys for any supported provider and Credlier will:
- Meter usage and enforce your spending caps
- Route traffic through your preferred models
- Track costs per agent, per tool, per run

**BYOK Security Model:**
We store your provider keys encrypted and use them only to call that provider. We can still see request metadata we need to enforce your cap. We never show the full key again after you save it. Rotate the provider key if you leave.

### What happens if I run out of credits?
Requests will fail with a 402 (Payment Required) error. You can enable auto-recharge to prevent this.
