Get Started in Minutes

from tango import TangoClient

client = TangoClient(api_key="your-api-key")

agencies = client.list_agencies(limit=10)
print(f"Found {agencies.count} agencies")

agency = client.get_agency("GSA")
print(f"Agency: {agency['name']}")

Most endpoints require an API key. You can obtain one from the Tango API portal.

const { TangoClient } = await import("@makegov/tango-node");

const client = new TangoClient({
    apiKey: process.env.TANGO_API_KEY,
});

async function main() {
    const agencies = await client.listAgencies({ limit: 5 });
    console.log("Found", agencies.count, "agencies");

    const dod = await client.getAgency("9700");
    console.log("Agency:", dod.name);
}

main();
