Enterprise plans work the same way as self-serve — the difference is the unit. Where self-serve bills in USD, Enterprise plans are billed in credits, and 1 credit costs $0.50. To map an enterprise rate to the self-serve page, multiply the credit rate by $0.50: for example, Photo Avatar video at 0.1 credits / sec is the equivalent of $0.05 / sec.
OAuth vs API Key: If you authenticate with an OAuth bearer token, usage is billed against your web plan, not the API tier.Using an API Key is recommended for automation and integration workflows. API key authentication provides higher concurrency limits and is more flexible and powerful for programmatic use.
This is the older Avatar III engine on the legacy v1/v2 endpoints — a different pipeline from the avatar_iii engine above. It is available to existing customers only and is not offered on the new developer platform. For all new integrations use the v3 engines: Avatar IV, Avatar V, or Avatar III.
Concurrent jobs include any asynchronous generation in progress: Video Agent sessions, avatar video renders, and video translations. Exceeding the limit returns 429 Too Many Requests with a Retry-After header.
Maximum file size: 32 MB. The same limit applies to files provided by URL. For larger files, use the direct upload flow (POST /v3/assets/direct-uploads).
Supported types: Image (PNG, JPEG), video (MP4, WebM), audio (MP3, WAV), and PDF.
All endpoints enforce rate limits. When exceeded, the API returns 429 Too Many Requests with a Retry-After header indicating the number of seconds to wait before retrying.
