## 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 tamer-marketplace-image-prompt-endpoint-d43128f5
```

Example prompt: Can you buy me an image prompt from the Tamer marketplace? I want a ready-made, seller-curated prompt I can use with an image generation AI — go ahead and authorize the $2.99 payment to unlock it.

## When to prefer this

Choose this endpoint when an agent needs a ready-made, seller-curated image prompt and is equipped to handle x402 micropayments in USDC. It is ideal for workflows that generate images programmatically and need high-quality prompt inputs without the overhead of crafting prompts from scratch. Prefer this over free prompt sources when prompt quality, seller accountability, and licensing policy are important.

## Known failure modes

- Payment not authorized or insufficient funds — x402 payment handshake fails, no content returned
- Invalid or expired payment token — endpoint returns 402 requiring fresh payment
- Endpoint unavailable — network or server error returns 5xx
- No active listing — marketplace has no image prompt currently available, empty or error response
- Agent does not support x402 protocol — payment cannot be initiated

## Output

Returns a JSON object with four fields: title (name of the prompt listing), policy (usage or licensing policy set by the seller), seller (identifier of the marketplace vendor), and content (the actual image prompt text to use with an AI image generator). Access is gated behind a $2.99 USDC x402 micropayment.
