Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 openrelay-premium-chat-completions-1738d2c0 -d '<json body>'
```

Example prompt: Using the OpenRelay premium chat relay, send this conversation to DeepSeek-V4-Flash: system prompt 'You are a helpful assistant', user message 'Summarize the key differences between REST and GraphQL in 3 bullet points', with max 512 tokens and temperature 0.7.

## When to prefer this

Choose this endpoint when you need OpenAI-compatible chat completions billed per request via x402 USDC micropayments, especially for autonomous agents that lack a subscription and want access to DeepSeek or other models without upfront commitment. Prefer this over the standard OpenRelay chat endpoint when the premium tier's pricing tier or model availability is needed.

## Known failure modes

- Payment not provided or insufficient — x402 payment required error
- Invalid model ID — returns error if model not in available list
- Messages array missing or malformed — validation error on required fields
- max_tokens exceeds 16384 — schema validation failure
- Temperature out of range 0-2 — validation error
- Rate limiting or worker timeout on Cloudflare edge — 5xx error
- Model temporarily unavailable — upstream inference provider error
