## 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-deepseek-v4-pro-chat-completions-x402-pay-per-call-38598f3b -d '<json body>'
```

Example prompt: Ask DeepSeek V4 Pro to explain the difference between Base and Solana for smart contract development — pay per call with no account needed, just deduct the $0.001 USDC from my wallet.

## When to prefer this

Choose this endpoint when you need DeepSeek V4 Pro chat completions with zero account setup, want to pay only per successful call in USDC, or are building a crypto-native or autonomous agent that needs trustless, key-free LLM access. It is ideal for bursty or experimental workloads where a subscription would be wasteful and for agents that hold a crypto wallet and need to invoke LLM inference as a paid action.

## Known failure modes

- Payment rejected or insufficient USDC balance — call is not charged
- Invalid or malformed message array — 400 error returned
- x402 payment handshake fails due to network issues on Base or Solana
- Model temporarily unavailable — upstream inference error
- Rate or quota limits on the underlying DeepSeek model

## 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 a JSON object with an OpenAI-compatible chat completion structure: a choices array containing the assistant's message content and finish_reason, plus a usage object with prompt_tokens and completion_tokens counts.
