Get started

Your first request, how authentication works, and which way to integrate.

• Quickstart Get an API key, list your datasets, describe one, query it and read the answer, in about five minutes.
• Authentication Every credential Halo issues, which to use when, the header they go in, what scopes do, and how an API key acts as its person.
• API keys Turn on the API, make a key, pick its scopes and expiry, store it, roll it with a 24-hour overlap, revoke it, and know what stops it and what to do if one leaks.
• Choose an integration REST API, signed embed, public link or MCP server. A decision table for what each is for and who it reads as, with one example of each.
