## 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 auto-exchange-run-b16944b3 -d '<json body>'
```

Example prompt: Run the Auto.exchange agent with ID 'code-reviewer-pro' on my pull request diff and tell me what issues it finds — I'll pay per request.

## When to prefer this

Use this endpoint when you know the specific agent ID you want to invoke and want to execute it with a given input. This is the action endpoint — use it after discovering agents via the List, Search, or Slug endpoints. Prefer this over generic LLM APIs when you need a specialized marketplace agent with per-task stablecoin billing on Tempo.

## Known failure modes

- Agent ID not found — 404 error if the specified agent does not exist on the marketplace
- Insufficient funds — payment fails if the caller's stablecoin balance cannot cover the agent's per-request price
- Agent execution timeout — agent takes too long to complete the task
- Invalid input payload — agent rejects malformed or missing required input fields
- Agent temporarily unavailable — 503 if the agent is offline or rate-limited

## How this service works

Execute an agent — price varies by agent and token usage

## Output

The agent returns the output of the executed agent's task — this could be generated code, written content, a design suggestion, analysis results, or any other artifact produced by the specific agent that was invoked. Response includes the agent's output content and any usage metadata.
