Zest

Zest Equity is a DIFC/ADGM-based provider of digital infrastructure for private-market transactions across the Middle East and North Africa. Its SPV-as-a-Service (SPaaS) platform lets partners create Cayman/DIFC Special Purpose Vehicles, run FSRA-regulated escrow, and arrange private capital deals. The Zest Public API gives partners programmatic access to the core workflow: OAuth 2.0 JWT-Bearer authentication, contract-validated SPV creation requests, bulk investor onboarding, subscription processing (signed forms + funding receipts), and nine HMAC-SHA256-signed webhook lifecycle events, with Idempotency-Key support on write endpoints and a uniform error envelope.

Zest publishes 8 APIs on the APIs.io network, including Authentication API, Contracts API, Investors API, and 5 more. Tagged areas include Company, SPV, Private Markets, Fintech, and Equity.

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

Zest’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, sandbox, engineering blog, and 18 more developer resources.

APIs 8

Individual APIs this provider publishes, each with its own machine-readable definition.

Zest Authentication API

OAuth 2.0 JWT-Bearer assertion grant. Exchange a partner-signed JWT for a short-lived bearer access token, then send that token in the Authorization header on every partner API ...

Zest Contracts API

Read-only access to the spaas-contract registry (templates, catalogs, primitives, samples) used to validate SPV-request `attributes`.

Zest Investors API

Bulk-create investor records with partial-success semantics. Each row carries its own status / error envelope so a single bad row never fails the batch.

Zest SPV Requests API

Submit SPV creation requests, inspect their lifecycle, and cancel pending ones. SPV requests are reviewed by Zest admins and produce SPV materialisation on approval.

Zest Subscription Forms API

Upload signed subscription forms (PDF or image) for partner-managed subscriptions. Files are streamed to private storage and referenced on the Bid.

Zest Subscription Fundings API

Upload wire-transfer receipts plus funding metadata. Strict order: a signed form must already be on record before fundings can be uploaded.

Zest Subscriptions API

Create one or more subscriptions for a single SPV.

Zest System API

Service health and OpenAPI introspection endpoints.
