## 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 x402-slinkylayer-ai-chat-completions-proxy-3282b918 -d '<json body>'
```

Example prompt: Using my SlinklyLayer proxy (ID: proxy-abc123), send this conversation — system: 'You are a helpful assistant', user: 'Explain quantum entanglement in simple terms' — and give me the AI's response.

## When to prefer this

Choose this endpoint when you need a pay-per-call, metered chat completion routed through a specific SlinklyLayer proxy ID — ideal for agents that require cost-controlled LLM access billed per request via the x402 micropayment protocol rather than a subscription-based API key model.

## Known failure modes

- Invalid or unknown proxy ID returns 404 or authorization error
- Malformed message array causes 400 bad request
- Insufficient USDC balance or payment failure blocks the request
- Upstream model timeout results in 504 or error response
- Missing required fields (messages array) returns validation error

## How this service works

Create a chat completion for a given conversation.

## Output

Returns a chat completion object containing the AI-generated assistant message, finish reason, token usage statistics, and any relevant metadata from the proxied model, following the standard OpenAI-compatible chat completion response format.
