## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eudata402-multi-model-llm-gateway-70b91886
```

Example prompt: Use the budget LLM gateway to generate a short professional bio for me — pick Llama 3 as the model, keep it under 200 tokens, and use a temperature of 0.7.

## When to prefer this

Choose this endpoint when you need affordable, keyless access to a wide variety of open-source LLMs (DeepSeek, Llama, Qwen, Gemma, Mistral, Phi) at a flat $0.005/call price without managing individual provider API keys. Ideal for agents that need text generation as a sub-task, want to experiment with multiple budget models, or require reasoning-capable open-source models without paying premium closed-model prices.

## Known failure modes

- Invalid model ID returns an error listing available models
- Prompt or messages field missing causes a 400 bad request
- max_tokens exceeding 1500 is rejected with a validation error
- Overloaded model or gateway timeout returns a 5xx without charging
- Unsupported temperature value outside 0–1 range causes validation failure

## How this service works

Flat-price multi-model LLM gateway: pick any of 60+ budget models (DeepSeek, Llama, Qwen, Gemma, Mistral, Phi, GPT-OSS...) at one price — see GET /models. POST {prompt|messages, model?, max_tokens?, temperature?}. Returns {model, text, usage}. Default DeepSeek V4 Flash. Failed/over-tier requests are never charged.

## Output

Returns a JSON object with: `model` (the model ID that handled the request), `text` (the generated completion or chat reply), and `usage` (token counts for prompt, completion, and total). Failed or over-tier requests are never charged.
