Interactive demo · Decionis API × APIMatic

Watch a coding agent build agent spending on Decionis Shield from one prompt.

Install the Decionis APIs Context Plugin, ask your agent for SpendGate, and open what it builds: an AI purchasing agent that asks Shield before every spend, holds ASKs until you approve, executes only ALLOWs and keeps the signed Decision Dossier, all through the SDK APIMatic generated.

How it works

From install to a guarded spending agent

The plugin gives your agent the Decionis SDK's real client, auth, methods, models and error types, so the code it writes is right the first time.

1

Install the plugin

One command adds the Decionis SDK skills (30 skills and a planner agent) to Claude Code, Cursor, GitHub Copilot or Codex.

$ npx context-plugins install https://merge.decionis-apimatic-poc.pages.dev/__downloads/plugin.zip
2

Ask for SpendGate

One prompt. The agent plans first: it reads the plugin's skills and the SDK map, and writes a contract sheet before a line of code.

3

Open what it built

Ask Shield for the whole queue, approve the hotel on your "phone", execute it, and open the signed dossier behind the verdict.

Runs on demo data through the same SDK until a Decionis key is set.

Under the hood

The Decionis calls behind it

All through the APIMatic TypeScript SDK, decionis-apis 0.6.0, shipped inside the context plugin.

Everything a developer needs, from one spec

APIMatic built all three from the Decionis Policy Evaluation API 0.6.0 and the Shield Spending Authority API 0.1.0, merged: 191 operations across 23 groups, in Decionis's own branding.
