StackAI plugin

Use StackAI through Corsair: one client, typed API calls. Use a StackAI personal API key or supported user token. The hosted origin is https://api.stack-ai.com; configure baseURL for a private deployment. The key needs projects.read, projects.run, and analytics.read as appropriate. Replace example_input with a node ID from your project’s I/O schema. Start, cancel, and resume return the JSON body and the actual Location header; a successful response does not mean the run has completed. The plugin prevents Corsair retries from resending writes, though custom root handlers may delay and reprocess the failure. Reconcile ambiguous write failures before manually retrying. Never attach credentials to an untrusted Location URL. What you get:

Setup

Install

npm install corsair @corsair-dev/stackai better-sqlite3
npm install --save-dev @types/better-sqlite3

yarn add corsair @corsair-dev/stackai better-sqlite3
yarn add --dev @types/better-sqlite3

pnpm install corsair @corsair-dev/stackai better-sqlite3
pnpm install --save-dev @types/better-sqlite3

bun add corsair @corsair-dev/stackai better-sqlite3
bun add --dev @types/better-sqlite3

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { stackai } from '@corsair-dev/stackai';

export const corsair = createCorsair({
	plugins: [
		stackai(),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

With multiTenancy: true, scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

API Key (Recommended)

Store the StackAI API key before the first call: pnpm corsair setup --plugin=stackai --tenant=acme api_key=<your-key> (leave out --tenant without multiTenancy), or pass it as key in the plugin options. With Hub, each tenant enters their own key on the connect page. See API key auth.

stackai()

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'stackai',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

List runs

const tenant = corsair.withTenant('acme');
await tenant.stackai.api.runs.list({ page_size: 25 });

Start a project run

const tenant = corsair.withTenant('acme');
await tenant.stackai.api.runs.start({
	project_id: 'example-project',
	input: { example_input: 'Hello' },
});

See the full list on the API page.
