Versioning and what changed.
Versioning
The API is versioned in the path (/api/v1). Within v1 we only make additive changes: new endpoints, new optional fields, new enum values and new error codes. Write your code to ignore fields it doesn't know. Anything breaking would ship as /api/v2 with notice here first.
Changes
| Date | Change |
|---|---|
| 2026-10-29 | Pay-as-you-go billing: the API is paid from a USD API balance (per second of video, per image), with top-ups, auto-recharge and a Console. API keys can start 200 generations an hour. New errors insufficient_balance, concurrency_limit, developer_account_suspended; billing fields on jobs, images and /developer/me. |
| 2026-10-29 | Developer API launch: API keys, rate limits, signed webhooks, OpenAPI spec, playground and the MCP connector for ChatGPT and Claude. |
