Overview - Corsair

Use Retell AI through Corsair: one client, typed API calls, local DB sync.

Lists are summaries. calls.list and chats.list omit transcripts; call calls.get or chats.get for the transcript, recording and analysis. Only the get operations save records locally.
Paging. Pass the returned pagination_key back as paginationKey while has_more is true. Set includeTotal: true to get total (Retell runs an extra count query for it).

What you get:

4 typed API operations
2 synced entities (calls, chats) for fast .search() / .list()

Setup

Install

npm install corsair @corsair-dev/retellai

yarn add corsair @corsair-dev/retellai

pnpm install corsair @corsair-dev/retellai

bun add corsair @corsair-dev/retellai

Add the plugin

corsair.ts

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

export const corsair = createCorsair({
	plugins: [
		retellai(),
	],
	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.

retellai()

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

Example API calls

List ended calls

const tenant = corsair.withTenant('acme');
await tenant.retellai.api.calls.list({
	limit: 50,
	filterCriteria: {
		call_status: {
			type: 'enum',
			op: 'in',
			value: ['ended'],
		},
	},
});

Write No write-style endpoint inferred; pick any operation from the API reference. See the full list on the API page.

Query synced data

Calls fetched with calls.get are kept locally.

const tenant = corsair.withTenant('acme');
const rows = await tenant.retellai.db.calls.search({
	data: { call_status: 'ended' },
	limit: 20,
});

Synced entities: calls, chats. See Database for filters and operators.
