}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 via character_id on POST /v1/images or POST /v1/videos.
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 inspectedrefs[]— 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.
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_01HXMQ7Z3K8Y2VNABCDEFGHJKM/save \
-H "X-Api-Key: $AUROUS_API_KEY"
const character = await fetch(
`https://api.aurous-labs.com/v1/characters/${id}/save`,
{ method: "POST", headers: { "X-Api-Key": process.env.AUROUS_API_KEY! } },
).then((r) => r.json());
console.log(character.status); // "ready"
import os, requests
r = requests.post(
f"https://api.aurous-labs.com/v1/characters/{character_id}/save",
headers={"X-Api-Key": os.environ["AUROUS_API_KEY"]},
).json()
print(r["status"]) # "ready"
Limits
- Rate limit: bucket
characters_post— 30 requests/min sustained, 60 burst per team.
Errors
| Code | HTTP | When |
|---|---|---|
invalid_request | 400 | Character is in a non-savable state (e.g. synthesizing, failed). |
resource_not_found | 404 | Unknown ID, soft-deleted character, or cross-team. |
Common pitfalls
- Save is idempotent on already-
readycharacters — calling it twice returns 200 both times withstatus: readyunchanged. Use this property to retry confidently. - A
synthesizingcharacter returns400— don’t call save until you’ve polled and seenstatus: reviewing. - After save, the character cannot be returned to
reviewing. To retry refs, callregenerate-ref(single pose) orresynthesize(all four).

Machine-readable failure code from the most recent synthesize/resynthesize attempt. One of synthesis_failed, synthesis_timeout, provider_unavailable — a closed set to switch on, not customer-facing prose. Null when the most recent attempt succeeded (or none has run yet). Set on failed, but NOT failed-exclusive: a failed resynthesize restores the character to its prior working status (reviewing) rather than overwriting a good generation, so a reviewing row can carry a non-null code here — check this field for failure, not status. Cleared on the next resynthesize attempt and on success.
null
API contract version applied at the time this row was minted (D25 — frozen for replay across future version bumps).
