Zest Equity

Zest Equity is the digital infrastructure for private-market transactions — built in MENA, used worldwide. Its SPV-as-a-Service platform lets partners create DIFC-regulated Special Purpose Vehicles, run FSRA-regulated escrow and deal-arranging, bulk-onboard investors, and process subscriptions. The Zest Public API exposes this workflow programmatically: OAuth 2.0 JWT-Bearer (RFC 7523, EdDSA) authentication, idempotent write endpoints, a versioned contract-template engine, and a nine-event HMAC-signed webhook surface — so fund managers, family offices, VCs, and PE firms can embed SPV setup, fund administration, and regulatory compliance directly inside their own product.

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

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

Zest Equity’s developer surface includes authentication, changelog, sandbox, documentation, API reference, getting-started guide, engineering blog, and 23 more developer resources.

APIs 8

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

Zest Equity 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 Equity Contracts API

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

Zest Equity 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 Equity 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 Equity 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 Equity 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 Equity Subscriptions API

Create one or more subscriptions for a single SPV.

Zest Equity System API

Service health and OpenAPI introspection endpoints.
