What is Haystack?
End-to-end NLP framework for building search, RAG, and question answering pipelines. Developed by deepset.
Searching YouTube with Haystack
This integration lets your Haystack agent search YouTube in real time via the Scavio API. The agent gets back structured JSON with video results, channel results, playlist results, transcripts -- ready for reasoning and decision-making.
Setup
Bash
pip install scavio-haystackCode Example
Here is a complete Haystack agent that searches YouTube using Scavio:
Python
from haystack.components.generators import OpenAIGenerator
from haystack_integrations.components.websearch.scavio import ScavioWebSearch
# ScavioWebSearch wraps Google web search (POST /api/v2/google). For YouTube
# data call POST /api/v1/youtube/search directly - see the YouTube guide.
# export SCAVIO_API_KEY=sk_live_your_key
web_search = ScavioWebSearch(top_k=5)
results = web_search.run(query="python web scraping tutorial")
context = "\n".join(doc.content for doc in results["documents"])
generator = OpenAIGenerator(model="gpt-5.5")
response = generator.run(
prompt="Summarise these search results:\n" + context
)
print(response["replies"][0])Full Working Example
A production-ready example with error handling:
Python
from haystack import Pipeline
from haystack.components.builders import PromptBuilder
from haystack.components.generators import OpenAIGenerator
from haystack_integrations.components.websearch.scavio import ScavioWebSearch
# ScavioWebSearch wraps Google web search (POST /api/v2/google). For YouTube
# data call POST /api/v1/youtube/search directly - see the YouTube guide.
# export SCAVIO_API_KEY=sk_live_your_key
template = """
Based on these web search results, answer the question.
{% for doc in documents %}{{ doc.content }}
{% endfor %}
Question: {{ query }}
Answer:
"""
pipe = Pipeline()
pipe.add_component("search", ScavioWebSearch(top_k=5))
pipe.add_component("prompt_builder", PromptBuilder(template=template))
pipe.add_component("llm", OpenAIGenerator(model="gpt-5.5"))
pipe.connect("search.documents", "prompt_builder.documents")
pipe.connect("prompt_builder", "llm")
query = "python web scraping tutorial"
result = pipe.run({"search": {"query": query}, "prompt_builder": {"query": query}})
print(result["llm"]["replies"][0])Pricing
