Quickstart

Fetch your first multichain balances in under a minute.

1. Create an API key

Head to the API Keys page and create a key. Copy it immediately — it's shown only once.

2. Call the Balances endpoint

curl "https://chainkit.ai/v1/balances/0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045?chains=ethereum,base" \
  -H "Authorization: Bearer thw_live_xxxxxxxx"

3. Read the response

You get normalized balances plus credit and rate-limit headers on every response.
