how it works

From query to dataset

Step 01

Query planning

Query rewritten into multiple retrieval prompts covering different phrasings and event types.

Step 02

Retrieval

50,000+ pages scanned per job at ~10,000 pages/min.

Step 03

Clustering

Related pages grouped into single event records using the Leiden algorithm.

Step 04

Validation

Each cluster scored by LLM validators against your query. Irrelevant clusters dropped.

Step 05

Structured output

One JSON object per event, with source citations and dynamic schema.

Output

Structured records, not ranked links

Each result is a validated, deduplicated event, with citations, schema, and no token billing.

Integration

In production in under an hour

One REST endpoint for every run, with the same API key as the News API.

import requests

run = requests.post(
    "https://api.newscatcherapi.com/agent/runs",
    headers={"x-api-key": "YOUR_API_KEY"},
    json={
        "query": "Bank M&A deals announced in the US in the last 30 days",
        "mode": "standard",
        "max_rows": 50,
    },
).json()

run_id = run["run_id"]
const res = await fetch('https://api.newscatcherapi.com/agent/runs', {
  method: 'POST',
  headers: { 'x-api-key': 'YOUR_API_KEY', 'Content-Type': 'application/json' },
  body: JSON.stringify({
    query: 'Bank M&A deals announced in the US in the last 30 days',
    mode: 'standard',
    max_rows: 50
  })
})

const { run_id } = await res.json()
curl -X POST "https://api.newscatcherapi.com/agent/runs" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "Bank M&A deals announced in the US in the last 30 days",
    "mode": "standard",
    "max_rows": 50
  }'

FAQ

Is the Web Search Agent the same as the News API?

No. They're two products with their own endpoints, and both use one API key and one credit balance. The Web Search Agent is a web search API focused on real-world events. News API is a general news search API.

Is the Web Search Agent free to use?

Yes, there's a free tier. You get 10,000 free credits every 30 days. Beyond that, you need to upgrade to a paid plan.

How does billing work?

You pay per search, in credits, by mode:

FastStandardMax
First 50 results1,0003,0006,000
Each 50 more5001,5003,000
Prices in credits. 1,000 credits = $1.
How long does a search take?

A Fast search takes about 1 to 3 minutes, and Standard about 10 to 30. Max depends on the request.

How do I write a good query?
