Quickstart

ISTARI gives you three ways to work with the Global Organization Index (GOI): a curated dataset of ~20 million active, web-verified organizations across 232 countries. Pick the path that fits how you work.

No code

Use the GOI dashboard to search, filter, and export.

API

Query GOI programmatically over HTTP.

AI agent

Connect GOI to Claude, Cursor, or any MCP client.

Create an account

Create an account at index.istari.ai. The same login works for the GOI dashboard, the API, and GOI MCP.

Choose your path

Explore visually in the GOI dashboard, or generate an API key to go programmatic.

Use the GOI dashboard

The fastest way to see what GOI can do. No setup required.

Sign in at index.istari.ai.
Describe what you’re looking for in the search bar, or switch to keyword or similarity search.
Narrow with location and organizational filters.
Export the results or save them as a list.

See the GOI dashboard guide for the full walkthrough.

Use the API

Get an API key

In the GOI dashboard, open API keys and create a key. Keep it secret; it carries your plan’s quota.

Make your first request

Send a POST to /v2/search. The API auto-detects the search mode from your inputs. No mode name needed.

curl -X POST https://api.istari.ai/v2/search \
  -H "x-api-key: $ISTARI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "describe": "organizations that manufacture industrial heat pumps",
    "filters": { "country": ["Germany"] },
    "columns": ["domain", "name", "country"],
    "size": 25
  }'

import os, requests

resp = requests.post(
    "https://api.istari.ai/v2/search",
    headers={"x-api-key": os.environ["ISTARI_API_KEY"]},
    json={
        "describe": "organizations that manufacture industrial heat pumps",
        "filters": {"country": ["Germany"]},
        "columns": ["domain", "name", "country"],
        "size": 25,
    },
)
print(resp.json()["metadata"]["total"], "matches")

Read the response

Responses contain a data array of organization rows and a metadata object (total hits, mode, pagination cursor). See Search for every parameter and Reference for columns, limits, and errors.

Use an AI agent

GOI MCP is not yet listed in connector directories. Request access, then add it as a custom connector.

Request access

Submit the GOI MCP access request. We email you your Client ID, Secret, and MCP URL when your account is enabled.

Add GOI MCP

Add GOI MCP as a custom connector in Claude, ChatGPT, Cursor, or another MCP client. See Connect for client-specific steps.

See the GOI MCP overview for the available tools.
