## 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 farout-kimi-k2-6-chat-completions-x402-pay-per-call-d42c3007 -d '<json body>'
```

Example prompt: Using the Kimi K2.6 model on FarOut, send this message and pay per call in USDC: 'Explain the trade-offs between transformer and state-space architectures for long-context tasks' — use up to 512 output tokens and a temperature of 0.7.

## When to prefer this

Choose this endpoint when you need to call the Kimi K2.6 model specifically and want to avoid API key management or prepaid subscription overhead. It is ideal for autonomous agents that need pay-as-you-go LLM inference billed in USDC micropayments via x402, especially when operating without a persistent identity or account. Prefer this over managed LLM APIs when the calling agent already has a USDC wallet on Base and wants to pay only for actual usage.

## Known failure modes

- Insufficient USDC balance or x402 payment failure returns a 402 Payment Required response
- Invalid or unsupported model ID returns a 400 or 404 error
- messages array missing or empty triggers a validation error
- max_tokens set too high may cause quota or timeout errors
- Network or upstream model provider outage returns a 503 or 5xx error
- Malformed message role (not in enum) causes a schema validation rejection
