|
|
```
|

## Usage
|
|
|
|
This example uses the [`@agentic/search`](https://agentic.so/marketplace/projects/@agentic/search) tool.
|
|
|
|
```ts
|
|
import 'dotenv/config'
|
|
|
|
import { createLlamaIndexTools } from '@agentic/llamaindex'
|
|
import { AgenticToolClient } from '@agentic/platform-tool-client'
|
|
import { openai } from '@llamaindex/openai'
|
|
import { agent } from '@llamaindex/workflow'
|
|
|
|
async function main() {
|
|
const searchTool = await AgenticToolClient.fromIdentifier('@agentic/search')
|
|
|
|
const tools = createLlamaIndexTools(searchTool)
|
|
const weatherAgent = agent({
|
|
llm: openai({ model: 'gpt-4o-mini', temperature: 0 }),
|
|
systemPrompt: 'You are a helpful assistant. Be as concise as possible.',
|
|
tools
|
|
})
|
|
|
|
const response = await weatherAgent.run(
|
|
'What is the weather in San Francisco?'
|
|
)
|
|
|
|
console.log(response.data.result)
|
|
}
|
|
|
|
await main()
|
|
```
|
|
|
|

|
|
This example also uses the [@llamaindex/openai](https://ts.llamaindex.ai/docs/llamaindex/modules/models/llms/openai) provider, which adds OpenAI support to LlamaIndex.
|
|
|
|
_Note that OpenAI is not necessary to use Agentic; this is just an example._
|
|
|
|
<CodeGroup>
|
|
```bash npm
|
|
npm install @llamaindex/openai dotenv
|
|
```
|
|
|
|
```bash pnpm
|
|
pnpm add @llamaindex/openai dotenv
|
|
```
|
|
|
|
```bash bun
|
|
bun add @llamaindex/openai dotenv
|

## Running this example

|
|
|
|
<Info>
|
|
You'll need an [OpenAI API key](https://platform.openai.com/docs/quickstart)
|
|
to run this example. Store it in a local `.env` file as `OPENAI_API_KEY`.
|
|
</Info>

|
<Info>
|
|
The
|
|
[`@agentic/search`](https://agentic.so/marketplace/projects/@agentic/search)
|
|
tool comes with a generous free tier, but once that runs out, you'll need to
|
|
sign up for a paid plan and add an `AGENTIC_API_KEY` to your `.env` file.
|
|
</Info>
|
|
|
|
```sh
|
|
git clone git@github.com:transitive-bullshit/agentic.git
|
|
cd agentic
|
|
pnpm install
|
|
pnpm build
|
|
echo 'OPENAI_API_KEY=your-key' >> .env
|
|
npx tsx examples/ts-sdks/llamaindex/bin/weather.ts
