​
Overview

Retrieve ranked document chunks for RAG (Retrieval-Augmented Generation) integration. This endpoint returns the top chunks after reranking, allowing you to merge them with your own LLM responses.

​
Request

​
query
string
required
The search query string
​
filters
object
Filter search results by specific criteria
​
top_k
number
default:10
Number of chunks to return (1-100)
​
rerank
boolean
default:true
Apply reranking to improve relevance of results

​
Request Example

curl -X POST https://api.fintool.com/v1/search \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "Tesla autonomous driving progress",
    "filters": {
      "tickers": ["TSLA"],
      "doc_types": ["10-K", "10-Q", "8-K", "EARNINGS_CALL"]
    },
    "top_k": 10,
    "rerank": true
  }'

​
Response

​
chunks
array
Array of document chunks matching the search query
​
total_chunks
number
Total number of chunks returned
​
processing_time_ms
number
Processing time in milliseconds

​
RAG Integration Example

Here’s how to use the Search endpoint with your own LLM: 
import requests
import openai

# Step 1: Search for relevant chunks
search_url = "https://api.fintool.com/v1/search"
headers = {
    "Authorization": "Bearer YOUR_FINTOOL_API_KEY",
    "Content-Type": "application/json"
}

search_payload = {
    "query": "What is Tesla's autonomous driving strategy?",
    "filters": {"tickers": ["TSLA"]},
    "top_k": 5,
    "rerank": True
}

search_response = requests.post(search_url, headers=headers, json=search_payload)
chunks = search_response.json()["chunks"]

# Step 2: Build context from chunks
context = "\n\n".join([
    f"Source: {chunk['document_title']}\n{chunk['text']}"
    for chunk in chunks
])

# Step 3: Use with your own LLM
openai.api_key = "YOUR_OPENAI_API_KEY"

completion = openai.ChatCompletion.create(
    model="gpt-4",
    messages=[
        {
            "role": "system",
            "content": "You are a financial analyst. Use the provided context to answer questions."
        },
        {
            "role": "user",
            "content": f"Context:\n{context}\n\nQuestion: What is Tesla's autonomous driving strategy?"
        }
    ]
)

print(completion.choices[0].message.content)

​
Reranking

When rerank: true is set, the API applies a two-stage retrieval process:
1

Initial Retrieval

Vector similarity search retrieves candidate chunks
2

Reranking

A reranking model scores candidates for better relevance
3

Top-K Selection

Returns the top K chunks based on rerank scores
Reranking significantly improves result quality but adds ~200ms latency. Disable for faster responses when speed is critical.

​
Filtering Best Practices

Always include ticker symbols when searching for company-specific information to reduce noise and improve relevance.
  • Use 10-K for annual comprehensive data
  • Use 10-Q for quarterly updates
  • Use EARNINGS_CALL for management commentary
  • Use 8-K for material events
Specify date ranges to focus on recent or historical information:
"dates": {
  "start": "2024-01-01",
  "end": "2024-12-31"
}
