Instawork

Instawork is a flexible-staffing marketplace that connects businesses in hospitality, warehouse, events, retail, and food service with vetted hourly workers ("Pros") for short-term shifts across the USA and Canada. Businesses post or rebook shifts and Instawork's ML-driven "Smart assign" matching fills them, often within hours. Instawork's developer surface is agent-native: rather than a public REST API it ships a hosted Partner MCP server (finch.instawork.com/mcp/partner) secured with OAuth 2.1, plus a published Agent Skill (github.com/instawork/skills) that lets AI assistants such as Claude and Cursor search locations and positions, price shifts, and create bookings on a business partner's behalf. Backed by Craft Ventures, Greylock, GV, and Y Combinator.

Instawork publishes 1 API on the APIs.io network. Tagged areas include Company, Marketplace, Staffing, Gig Economy, and Hospitality.

Instawork’s developer surface includes authentication, documentation, support, engineering blog, pricing, signup flow, and 11 more developer resources.
