## 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 baron-power-play-ai-inference-f7774c8f -d '<json body>'
```

Example prompt: Use Baron Power Play to run a pay-per-call AI inference — send the prompt 'What are the top 3 benefits of autonomous agents?' as a POST request, with the title 'Benefits Query', a description of what I want, and expect a chat-completion-style text response back.

## When to prefer this

Choose this endpoint when you need AI inference with true pay-per-call economics and no account or API key setup, especially in autonomous agent workflows where budget control at the individual call level matters. Ideal for crypto-native applications using USDC on Base via the x402 protocol, or for low-volume use cases where a subscription is wasteful.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed input body missing required fields (title, description, input, output) returns validation error
- Network or Cloudflare Worker timeout if inference takes too long
- Invalid or missing x402 payment header results in payment rejection
- Base network congestion delays USDC settlement

## How this service works

Pay-per-call AI infrastructure for autonomous agents. USDC on Base, settled by Coinbase. No API key, no account, no subscription.

## Output

Returns a JSON object with a choices array containing message objects, each with a content field holding the AI-generated text response — structured like a standard OpenAI-compatible chat completion response.
