What is Haystack?
End-to-end NLP framework for building search, RAG, and question answering pipelines. Developed by deepset.
Searching Reddit Comments Tree with Haystack
This integration lets your Haystack agent search Reddit Comments Tree in real time via the Scavio API. The agent gets back structured JSON with comment text, authors, scores, depth -- ready for reasoning and decision-making.
Setup
Bash
pip install scavio-haystackCode Example
Here is a complete Haystack agent that searches Reddit Comments Tree 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 Reddit Comments Tree
# data call POST /api/v1/reddit/post/comments directly - see the Reddit Comments Tree guide.
# export SCAVIO_API_KEY=sk_live_your_key
web_search = ScavioWebSearch(top_k=5)
results = web_search.run(query="t3_1u1143i")
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 Reddit Comments Tree
# data call POST /api/v1/reddit/post/comments directly - see the Reddit Comments Tree 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 = "t3_1u1143i"
result = pipe.run({"search": {"query": query}, "prompt_builder": {"query": query}})
print(result["llm"]["replies"][0])Pricing
