seltz 1.5.0

Seltz Python SDK for AI-powered search

Seltz Python SDK

Official Python SDK for Seltz, the Web search engine for AI agents.

💾 Installation

pip install seltz

Requires Python 3.9 or higher.

⚡️ Quick Start

from seltz import Seltz

client = Seltz(api_key="your-api-key")

# Search the Web
response = client.search("best ai search engines", max_results=10)

# Access results
for document in response.documents:
    print(f"URL: {document.url}")
    print(f"Content: {document.content}")

Output:

URL: https://www.best-ai-search-engines.com
Content: Generative AI can make finding information faster and more intuitive.
If you’re tired of traditional search, explore some of the best AI-powered
search engines we've tested...

Answer

Get a natural-language answer grounded in Web search results, with citations:

from seltz import Seltz

client = Seltz(api_key="your-api-key")

response = client.answer("Who is Apple's next CEO?")

print(response.answer)
for citation in response.citations:
    print(f"Source: {citation.url}")

Answer (streaming)

Stream an answer as it is generated, instead of waiting for the full response. answer_stream yields events as they arrive: a citations event first, then text_delta chunks, then a terminal finish_reason. Inspect each event with event.WhichOneof("event"):

from seltz import Seltz

client = Seltz(api_key="your-api-key")

for event in client.answer_stream("Who is Apple's next CEO?"):
    kind = event.WhichOneof("event")
    if kind == "citations":
        for citation in event.citations.citations:
            print(f"Source: {citation.url}")
    elif kind == "text_delta":
        print(event.text_delta, end="", flush=True)
    elif kind == "finish_reason":
        print()

Streaming is also available asynchronously via AsyncSeltz — async for over the events:

import asyncio

from seltz import AsyncSeltz


async def main():
    async with AsyncSeltz(api_key="your-api-key") as client:
        async for event in client.answer_stream("Who is Apple's next CEO?"):
            kind = event.WhichOneof("event")
            if kind == "citations":
                for citation in event.citations.citations:
                    print(f"Source: {citation.url}")
            elif kind == "text_delta":
                print(event.text_delta, end="", flush=True)
            elif kind == "finish_reason":
                print()


asyncio.run(main())

Async

The same API is available asynchronously via AsyncSeltz — await each call:

import asyncio

from seltz import AsyncSeltz


async def main():
    client = AsyncSeltz(api_key="your-api-key")

    response = await client.search("best ai search engines", max_results=10)

    for document in response.documents:
        print(f"URL: {document.url}")
        print(f"Content: {document.content}")


asyncio.run(main())

To close the connection deterministically rather than leaving it to garbage collection, use AsyncSeltz as an async context manager (async with) or call await client.close() when done.
