## 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 zeroreader-sea-lion-27b-southeast-asian-languages-llm-cc7a21ba -d '<json body>'
```

Example prompt: Using the SEA-LION 27B model on ZeroReader, send this conversation: system prompt 'You are a helpful assistant fluent in Bahasa Indonesia', user message 'Jelaskan perbedaan antara machine learning dan deep learning dalam 3 kalimat singkat' — max 512 tokens, temperature 0.5.

## When to prefer this

Choose this endpoint when you need strong performance in Southeast Asian languages (Thai, Indonesian, Malay, Vietnamese, Tagalog, etc.) and want a large 27B-parameter model. Prefer it over smaller models like Llama 3.2 3B when language quality and nuance matter, and over English-focused models like BGE Large EN when the input/output is primarily in SEA languages.

## Known failure modes

- Payment not provided or insufficient — 402 Payment Required
- Messages array is empty or missing required role/content fields — 400 Bad Request
- max_tokens exceeds 4096 — validation error
- Temperature outside 0–2 range — validation error
- Model overloaded or unavailable — 503 Service Unavailable
- Streaming not supported in certain client configurations when stream=true
