Create project

POST /api/projects

Save a new editor draft project. Provide the project JSON under payload (project is accepted as an alias). The draft becomes editable at https://editor.zvid.io?project=<id>.

Authentication

Option 1: x-api-key: YOUR_API_KEY (header). API key for authentication. Create one in your dashboard.
Option 2: Authorization: Bearer YOUR_ACCESS_TOKEN. Dashboard JWT in Authorization: Bearer <token>, only on operations that explicitly list this scheme. Prefer x-api-key for REST integrations. OAuth for hosted MCP is a separate connection at https://mcp.zvid.io/mcp.

Create API keys at app.zvid.io/api-keys. Keep credentials on your server.

Parameters

This operation has no path, query, or additional header parameters.

Request

The shell examples read credentials from ZVID_API_KEY (or ZVID_ACCESS_TOKEN for Bearer authentication). Set that variable in your environment. Replace sample project, template, job, and asset identifiers with values from your own account.

A request body is required.

Schema definitions

The following definitions describe the fields referenced above. Expand a definition to inspect its complete contract.

RenderPayload

The payload accepted by render requests and stored templates, before variable substitution, conditions and scene iteration. Whole placeholders preserve the variable's type. Run authenticated validation to resolve values, enforce semantic rules and apply your account limits. Stored video templates require explicit positive scene durations.

Unknown properties are rejected. All listed constraints apply.
