Getting started

Get your first result in three API calls

  1. Get a key

    One call creates a free key, with no card needed. The key is shown only once.

  2. Look up hazard data

    Get hazard levels at a location, past events nearby and the datasets they come from.

  3. Run a model

    Start a run with any of the nine open models on your locations, then check its status.

For developers

Plain HTTP and open formats

An open schema

Locations, values and perils are described in one documented JSON format.

Agent tools

An MCP server lets an AI agent sign up, look up hazard data and run models.

Repeatable results

Data is versioned, so the same request next year gives the same result.

Make your first call

The quickstart takes about ten minutes.
