Credentials Setup

1. Get your API key from Typecast Dashboard
2. In n8n, add new credentials of type Typecast API
3. Enter your API key

Usage Example

1. Add the Typecast node to your workflow
2. Select a resource and operation (e.g., Speech > Text to Speech)
3. Provide required parameters (e.g., Voice ID, Text)
4. Connect and run your workflow

Quick Cloning Example

1. Add a node that outputs an audio file as binary data, such as Read/Write Files from Disk or an HTTP download node.
2. Add Typecast > Voice > Clone Voice.
3. Set Audio Binary Property to the binary property name from the previous node, usually data.
4. Set Voice Name and Model, then run the node.
5. Use the returned voice_id (uc_...) in a following Typecast > Speech > Text to Speech node by selecting Voice ID By ID.
6. When the cloned voice is no longer needed, pass the same uc_... ID to Typecast > Voice > Delete Cloned Voice.

Release validation

The release workflow validates and publishes a separate package manifest without development dependencies or development-only overrides. Source development pins are retained. The published package must pass the unchanged official community lint, build, request regression tests, and runtime dependency audit.

For a fresh local release check after installing dependencies:

npm run build
node --test tests/*.test.cjs
node scripts/prepare-release.cjs
npm --prefix .release-package run lint
npm --prefix .release-package run build
(cd .release-package && node --test tests/*.test.cjs && npm pack --dry-run)

The staging directory must not already exist. Only a version-matching v* tag triggers publication; PR and main builds validate without publishing.
