## 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 gigsai-chat-completions-deepseek-pay-per-call-055490bc -d '<json body>'
```

Example prompt: Ask the DeepSeek chat model to explain the difference between proof-of-work and proof-of-stake in plain English — keep the response under 300 tokens and use a temperature of 0.7.

## When to prefer this

Choose this endpoint when you need a quick, keyless, pay-per-call LLM completion using DeepSeek's chat model via the familiar OpenAI messages format, without committing to a subscription or managing API credentials. It is ideal for agent pipelines that need occasional AI text generation billed in micro-USDC payments. Prefer alternatives if you need streaming responses, outputs longer than 512 tokens, or access to models other than deepseek-chat.

## Known failure modes

- Payment not included or insufficient USDC — 402 Payment Required response
- Input messages array is empty or missing — 400 validation error
- max_tokens exceeds 512 — request rejected or clamped
- Input text exceeds ~16000 characters — request rejected or truncated
- Model field value ignored silently, always uses deepseek-chat
- DeepSeek backend unavailable — 502 or 503 error
- Temperature out of range (below 0 or above 2) — 400 validation error

## How this service works
