POST /v1/characters/{id}/save is the publication step of the synthesize flow. It moves a reviewing character to ready, cleans up temporary upload bytes from the synthesis pipeline, and makes the character referenceable on POST /v1/images via character_id. This endpoint costs no credits and dispatches no inference — it is purely a state transition.

​
When to use

  • The synthesize flow finished (status: reviewing) and you’ve inspected refs[] — the four poses look right and you’re ready to use the character.
  • You want to convert an idempotent intent (“create the character”) into a usable resource without doing extra work.
If the refs don’t look right, call POST /v1/characters/{id}/refs/regenerate (one pose) or POST /v1/characters/{id}/resynthesize (all four) instead. To discard, call DELETE /v1/characters/{id}.

​
Examples

curl -X POST https://api.aurous-labs.com/v1/characters/char_01HXMQ7Z3K8Y2ABCDEFGHJKM/save \
  -H "X-Api-Key: $AUROUS_API_KEY"

​
Limits

  • Rate limit: bucket characters_post — 30 requests/min sustained, 60 burst per team.

​
Errors

CodeHTTPWhen
invalid_request_error400Character is in a non-savable state (e.g. synthesizing, failed).
resource_not_found404Unknown ID, soft-deleted character, or cross-team.

​
Common pitfalls

  • Save is idempotent on already-ready characters — calling it twice returns 200 both times with status: ready unchanged. Use this property to retry confidently.
  • A synthesizing character returns 400 — don’t call save until you’ve polled and seen status: reviewing.
  • After save, the character cannot be returned to reviewing. To retry refs, call regenerate-ref (single pose) or resynthesize (all four).
