Output type: [`llm_json`](https://zshot-cli.com/reference/flags/common/output-type/) · Extension: [`.llm.json`](https://zshot-cli.com/reference/flags/common/file-name/)
License: [Pro](https://zshot-cli.com/support/licenses/pro)

Structured JSON produced by an LLM reading the rendered page. Requires a [configured LLM](/reference/llm_connections). You can specify a JSON Schema with [`--llm-format-expects`](/reference/flags/document/llm-format-expects) that will be sent to the underlying LLM if you would like the content to match an expected structure. If you do not specify a schema, the LLM will attempt to provide a JSON document that best matches your prompt.

## Example

**CLI**

```sh
zshot -t llm_json \
      -f - \
      --llm-format-model "anthropic://YOUR_API_KEY@" \
      --llm-format-prompt "Summarize the licenses" \
      https://zshot-cli.com/purchase/
```

**JSON** — `POST /` body for the [API](/reference/server/api), Pro license

```json
{
  "url": "https://zshot-cli.com/purchase/",
  "output_type": "llm_json",
  "llm_format_model": "anthropic://YOUR_API_KEY@",
  "llm_format_prompt": "Summarize the licenses"
}
```

**curl**

```sh
curl -X POST http://127.0.0.1:3000/ \
  -H "Content-Type: application/json" \
  -d '{"url":"https://zshot-cli.com/purchase/","output_type":"llm_json","llm_format_model":"anthropic://YOUR_API_KEY@","llm_format_prompt":"Summarize the licenses"}'
