## 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-pay-per-call-kimi-k2-7-chat-completions-x402-23d388a2 -d '<json body>'
```

Example prompt: Using FarOut's pay-per-call router, send this message to the Kimi-K2.7 model and get a response — I don't have an API key, so just pay the $0.001 USDC fee per call on Base: 'Explain the concept of zero-knowledge proofs in two paragraphs.'

## When to prefer this

Choose this endpoint when you need Kimi-K2.7 chat completions without any account registration, API key management, or subscription commitment. It is ideal for autonomous AI agents that can handle x402 micropayments natively on Base or Solana, one-off queries where a subscription is wasteful, or workflows requiring anonymous, pay-as-you-go LLM access billed transparently per request in USDC.

## Known failure modes

- 402 Payment Required — x402 payment not submitted or insufficient; endpoint returns a payment quote that the client must fulfill before retrying
- Invalid model path — if the model slug in the URL is wrong, a 404 or 400 is returned
- Malformed request body — missing 'messages' array or invalid JSON results in a 400 error
- Payment verification failure — on-chain payment not confirmed in time, request rejected without charge
- Rate or quota limits — upstream Kimi model may throttle if provider-side capacity is exceeded

## How this service works

Pay-per-call LLM inference over x402. Frontier models (GLM, GPT, Gemini, Kimi, DeepSeek, MiniMax) billed per request in USDC on Base or Solana mainnet. No API key, no account. The 402 quotes your exact request; failed calls are never charged.

## Output

Returns an OpenAI-compatible JSON object containing the assistant's reply message (role + content), a finish_reason (e.g. 'stop'), and token usage stats (prompt_tokens, completion_tokens). Failed or unpaid calls are never charged.
