Arkestro

Arkestro is a predictive procurement orchestration platform for enterprise sourcing teams, applying negotiation science, supplier science and process science to run competitive sourcing events at scale. The platform covers sourcing events and their schedules, supplier organizations and contacts, corporate item and category catalogs, purchase orders, document and quote submissions, awards, and event analytics. It serves automotive, oil and gas, high-tech manufacturing, construction, financial services and food and beverage buyers. Arkestro publishes a public OpenAPI 3.1.1 contract for its API V2 at api.arkestro.com and operates an OAuth 2.1 remote MCP server, though its developer documentation portal sits behind a customer sign-in wall.

Arkestro publishes 13 APIs on the APIs.io network, including Awards API, business unit API, corporate categories API, and 10 more. Tagged areas include procurement, sourcing, supply-chain, spend-management, and e-sourcing.

The Arkestro catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Arkestro’s developer surface includes documentation, API reference, support, engineering blog, authentication, and 25 more developer resources.
