Overview - Corsair

Use Qdrant through Corsair: one client, typed API calls. Works with self-hosted Qdrant and Qdrant Cloud. Each account stores its cluster URL as base_url next to its API key. The URL is never taken from endpoint input. A stored URL must use https and a public host; pin a local or private cluster such as http://localhost:6333 or http://qdrant:6333 with the baseUrl option. What you get:

29 typed API operations

Setup

Install

npm install corsair @corsair-dev/qdrant

yarn add corsair @corsair-dev/qdrant

pnpm install corsair @corsair-dev/qdrant

bun add corsair @corsair-dev/qdrant

Add the plugin

corsair.ts

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

export const corsair = createCorsair({
	plugins: [
		qdrant({
			baseUrl: 'https://xyz-example.eu-central.aws.cloud.qdrant.io:6333',
		}),
	],
	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.

API Key (Recommended)

No setup required yet. When you make your first request as a tenant, Corsair prompts for the API key.Pass baseUrl to pin one cluster for every account, or leave it out and store base_url per account.

qdrant({
	baseUrl: 'https://xyz-example.eu-central.aws.cloud.qdrant.io:6333',
})

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: 'qdrant',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

Find the nearest neighbours of a vector

const tenant = corsair.withTenant('acme');
await tenant.qdrant.api.query.points({
	collectionName: 'docs',
	query: [0.12, 0.08, 0.91, 0.33],
	filter: {
		must: [{
			key: 'lang',
			match: { value: 'en' },
		}],
	},
	limit: 5,
	with_payload: true,
});

Store embeddings with their payload

const tenant = corsair.withTenant('acme');
await tenant.qdrant.api.points.upsert({
	collectionName: 'docs',
	points: [{
		id: 1,
		vector: [0.12, 0.08, 0.91, 0.33],
		payload: { url: 'https://example.com/guide', lang: 'en' },
	}],
});
