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.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Zest Equity the way a machine reads it — 23 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Zest Equity scores 47.4/100 (developing), with a separate agent-readiness read of 36/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Zest Equity
Each block below is one kind of artifact we hold for Zest Equity. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 8
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
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.

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Arazzo Workflows 2
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
Zest — authenticate and create an SPV request
Mint an access token then submit and read back a contract-validated SPV creation request.
ARAZZOZest — onboard investors and record a subscription
Bulk-create investors, subscribe one to an SPV, then upload the signed form and funding receipt in strict order.
ARAZZOEvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Zest Equity Webhooks
ASYNCAPISecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Zest Equity, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
