## 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 ai-agent-hub-ad-impression-retrieval-6c191a2b -d '<json body>'
```

Example prompt: Fetch the ad payload for ad ID 'ad_abc123' from AI Agent Hub so I can display it — use my agent ID 'agent_xyz' for attribution.

## When to prefer this

Use this endpoint when an AI agent needs to fetch and display a specific ad by its known ID, particularly within the AI Agent Hub ecosystem where micropayment-based ad monetization is expected. Prefer this over generic ad networks when you already have a specific adId and want per-impression attribution to a registered agent ID.

## Known failure modes

- Invalid or unknown adId returns an error or empty payload
- Missing adId field causes a 400 bad request
- Payment failure prevents ad retrieval
- Network timeout on the Render-hosted backend
- Invalid agentId format may cause attribution failure but not block the request

## How this service works

Pay a fraction of a cent to retrieve an ad payload for a given adId

## Output

Returns a structured ad payload containing the creative content (e.g. text, image URL, link, title, description) for the specified ad, and records that an impression occurred. The micropayment of $0.001 USDC is charged per successful call.
