API

WEBOT API · Chatterbox

Generate from your server with your WEBOT account credits.

Use your 120-character WEBOT customer key (a–z, A–Z, 0–9). Send Authorization: Bearer YOUR_KEY. Keys are secrets: call from a server, never from public frontend code. Results come from verified webhooks and remain saved if your stream disconnects.
1. Configure your server
WEBOT_BASE_URL=https://webot.online
WEBOT_API_KEY=<your-server-side-WEBOT-key>

This base URL is resolved from verified domain mappings and your direct creator reseller. Forwarded Host headers are not trusted. New custom reseller domains need DNS, TLS and platform verification before activation.

2. Quote, then generate
MethodEndpointPurpose
POSThttps://webot.online/api/v1/models/creative_67acb9fd26e11a7334b00830/quoteValidate input and calculate credits (no deduction).
POSThttps://webot.online/api/v1/models/creative_67acb9fd26e11a7334b00830/requestsReserve quoted credits and queue an asynchronous job.
GEThttps://webot.online/api/v1/models/creative_67acb9fd26e11a7334b00830/requests/{request_id}/resultRead your saved result: 202 pending, 200 terminal.
GEThttps://webot.online/api/v1/models/creative_67acb9fd26e11a7334b00830/requests/{request_id}/eventsAuthenticated SSE: generation / terminal events.

Send JSON {"input":{…}} to quote. Send the same input plus integer quoted_credits to generate, with Authorization: Bearer … and Idempotency-Key. Use a unique 16–128 character key per new job; persist it and reuse the same key and input on any uncertain response. Never retry with a new key: that creates a second chargeable job.

Credits are reserved only after validation and a durable request is saved. A changed quote or insufficient balance returns 409. Credits exclude purchase taxes. The quoted amount is an initial reservation. After generation, the final charge replaces it using confirmed usage. Any verified unused allocation becomes available automatically; additional usage may require more credits. Missing billing stays pending, including for failed jobs.

3. Input example

Save this as input.json. Replace sample prompts, files and media URLs with your own. Schemas do not guarantee provider acceptance of the content.

5. Receive all results

The response includes a stable WEBOT request_id, events_url and result_url. Subscribe with a Bearer-authenticated HTTP stream. Nonterminal streams end after 25 seconds; reconnect to the same URL after at least 1.5 seconds. Current saved state is replayed immediately, including completion that happened while disconnected. A terminal event contains the result envelope. The JSON terminal flag describes generation completion. Keep reconnecting while financial_pending is true; stop after the terminal event confirms financial settlement. Never poll provider status/results. Native browser EventSource cannot send a Bearer header; keep the key on your server.

Completed output contains the full model result, including every generated media/document item, not just the first URL. Failed output is null with error and refund_state. Results are strictly limited to the key owner, including on reseller domains. Model-independent aliases: /api/v1/requests/{request_id}/result and /events. Revoking a key blocks subsequent reads and streams; saved results remain accessible with another valid key of the same account.

6. Schemas and parameter defaults

Required fields are marked with *. Required text must contain non-whitespace content. Defaults apply when an optional parameter is omitted; null, false, 0 and an empty array are distinct values. “No documented default” means WEBOT does not invent one. Examples are sample inputs, not defaults. WEBOT generation constraints can require an explicit value even when the provider publishes an automatic default.

Input schema · fields, constraints and defaults

How to use Resemble AI Chatterbox — Chatterbox

Type the words you want spoken. The model reads them aloud using the voice and speech controls available here.

Required inputs

  • Text: The actual text to be read or processed. Put the content here, rather than instructions about what the voice or tool should do, unless the documentation says otherwise.

Workflow

  1. Prepare your source material and fill the required inputs above. Review the supported settings for this model.
  2. Sign in to calculate the credit estimate. Review the estimate before choosing Generate.
  3. Keep this model page open while the request runs. Completed results arrive in the result area; use the available player or download controls to review the output.

When to use this workflow

  • Create narration or a voice-over.
  • Turn a written passage into spoken audio.

Key settings

Text
The actual text to be read or processed. Put the content here, rather than instructions about what the voice or tool should do, unless the documentation says otherwise. Maximum characters: 300
Voice
The speaking voice or speaker identity to use. It changes who the speech sounds like; it does not translate your text automatically. Use the supported voices and languages.
Custom Audio Language
The language to recognise or produce, depending on the task. A source language is the input language; a target language is the desired output language. This setting is separate from the language of this help window. Supported choices: "english", "arabic", "danish", "german", "greek", "spanish", "finnish", "french", "hebrew", "hindi", "italian", "japanese", "korean", "malay", "dutch", "norwegian", "polish", "portuguese", "russian", "swedish", "swahili", "turkish", "chinese"
Exaggeration
How strongly the supported voice or expression is stylised. Stronger expression can sound more dramatic but may be less natural; try a short sample before a long run. Minimum: 0.25. Maximum: 2
Temperature
How varied or unpredictable a text model’s choices are. Lower values tend to be more consistent; higher values allow more variety and can increase mistakes. It is not a factual-accuracy slider. Minimum: 0.05. Maximum: 2
CFG Scale
How strongly the generation is guided by your instructions. Higher values can push it to follow the prompt more closely but may cause harsh colours or unnatural results in some models. Lower values allow more freedom. Keep the documented default for a first attempt. Minimum: 0. Maximum: 1
