Run a prompt against an open-weight 20B-class language model with automatic failover across multiple inference backends, returning generated text.

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 skill-audit-llm-chat-completion-f27d53f7 -d '<json body>'
```

Example prompt: Send this prompt to the open-weight LLM with a system instruction saying 'You are a concise technical assistant' and generate up to 1000 tokens: 'Explain the difference between TCP and UDP in plain language.'

## When to prefer this

Choose this endpoint when you need reliable open-weight LLM inference and cannot tolerate downtime from a single provider — the automatic multi-backend failover ensures continuity even when individual inference providers are down or rate-limiting. Prefer it over direct model API calls when resilience matters more than latency optimization, or when you want to avoid vendor lock-in with a pay-per-call model at $0.02 USDC.

## Known failure modes

- All inference backends simultaneously unavailable or overloaded — returns an error with no generated text
- Prompt or system string exceeds model context window — may return truncated output or an error
- max_tokens set to 0 or above 4000 — likely rejected with a validation error
- temperature outside 0-2 range — may cause unexpected behavior or rejection
- Empty or missing prompt field — likely returns an error or empty response
- Payment of $0.02 USDC not fulfilled — request rejected by x402 payment gate

## How this service works

Run a chat completion against an open-weight 20B-class model — plain prompt in, text out, with automatic failover across independent inference backends so a single call still answers when any one provider is down or rate-limiting

## Output

A plain text string containing the model's generated response to the supplied prompt, produced by an open-weight 20B-class model routed through whichever inference backend is currently available and not rate-limited.
