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 citiview-gpt-oss-120b-chat-completions-87682631
```

Example prompt: Ask the gpt-oss-120b model: 'Explain the trade-offs between transformer and state-space models for long-context tasks' — use up to 1024 output tokens and keep temperature at 0.7.

## When to prefer this

Choose this endpoint when you need a powerful open-weight 120B reasoning model with tool calling and prefer pay-per-request x402 micropayment billing over subscription API keys. Ideal for agents that need OpenAI SDK compatibility without a fixed API key arrangement, or when cost-per-call transparency matters. Prefer over smaller models (like Llama 3.1 8B sibling) when task complexity demands stronger reasoning.

## Known failure modes

- Payment failure if USDC balance is insufficient for x402 transaction
- Prompt too long exceeding context window limits
- Tool call schema malformed causing parse errors
- Temperature or max_tokens out of valid range
- Network timeout on long reasoning responses
- Model unavailability or rate limiting on the upstream provider
