heygen/starfish, served by Comfy Router from HeyGen.
Quick start
Create a key at platform.comfy.org/profile/api-keys and export it asCOMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP.
Model ID: heygen/starfish
Endpoint: POST https://api.comfy.org/v2/models/heygen/starfish
Schema
Input
string
Type of the input: ‘text’ for plain text, ‘ssml’ for SSML markup. Defaults to ‘text’
string
Base language code (e.g. ‘en’). Auto-detected from text when omitted
string
BCP-47 locale tag (e.g. ‘en-US’). When set, language is inferred from locale
number
Speed multiplier (0.5-2.0)Range:
0.5 to 2Format: doublestring
required
Text to synthesize (1-5000 characters)
string
required
Voice ID to use. The voice must support the starfish engine
GET /v2/models/heygen/starfish/openapi.json, the same document it validates a call against before the request reaches the provider.
Output
Router does not publish an output schema for this model.Examples
Input
Before you ship
The snippets above are the shortest working call. Three things are the same for every model and are documented once on the Comfy Router headers page: send anIdempotency-Key on every paid call and reuse it when you retry, expect the connection to be held up to Router’s 10 minute deadline, and keep X-Comfy-Request-Id from every response. The SDKs do all three for you; the cURL tab does none of them. On failure, X-Comfy-Error-Type names the bucket, and a 422 means the body failed the model’s schema and was never billed.
Headers
Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.
Quick Start
Typed error handling in Python and TypeScript, reading the 422, walking the catalog.
Limitations
What Router does not do today, and what to use instead.
