API: Vault media and signed uploads

The Vault holds a creator's photos, videos and voice notes, sorted in folders. Each item is Free, Teaser or Paid with a Stars price. Files never travel through the API: you ask for a signed upload URL, send the file there, then confirm.

  ],
  "next_cursor": null
}

Without creator_id the API answers 400.

Upload a file #

Three calls: ask for a signed URL, send the file there, confirm.

Step 1. POST /media/uploads · can_setup

curl -X POST https://api.lanachat.ai/v1/media/uploads \
  -H "Authorization: Bearer $LANACHAT_TOKEN" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"creator_id": "cr_lea", "file_name": "beach-01.jpg", "content_type": "image/jpeg", "size_bytes": 2483201, "folder_id": "vf_3"}'

{
  "upload_id": "up_7781",
  "url": "https://uploads.lanachat.ai/w/7Hq2/up_7781?X-Signature=…&X-Expires=1759760100",
  "method": "PUT",
  "headers": { "Content-Type": "image/jpeg" },
  "expires_at": "2026-10-06T14:35:00Z"
}

The URL is valid 15 minutes.

Step 2. Send the file with PUT to url, with exactly the headers given (no Authorization header there).

curl -X PUT "https://uploads.lanachat.ai/w/7Hq2/up_7781?X-Signature=…&X-Expires=1759760100" \
  -H "Content-Type: image/jpeg" --data-binary @beach-01.jpg

Step 3. POST /media/uploads/{upload_id}/complete · can_setup

curl -X POST https://api.lanachat.ai/v1/media/uploads/up_7781/complete \
  -H "Authorization: Bearer $LANACHAT_TOKEN" \
  -H "Idempotency-Key: $(uuidgen)"

{
  "id": "med_5521",
  "creator_id": "cr_lea",
  "type": "photo",
  "status": "processing",
  "folder_id": "vf_3",
  "access": "paid",
  "stars": null,
  "description": null,
  "preview_url": null,
  "created_at": "2026-10-06T14:21:40Z"
}

status goes from processing to ready (previews and the Telegram copy are made) or failed with a reason. A webhook media.ready tells you when, see Webhooks. Accepted: JPEG, PNG, HEIC, MP4, MOV, OGG and M4A, up to 2 GB.

Get a media #

GET /media/{id} · can_setup

curl https://api.lanachat.ai/v1/media/med_5521 \
  -H "Authorization: Bearer $LANACHAT_TOKEN"

The answer is the media object, with its preview and where it is used. An unknown id answers 404.

Price and describe #

PATCH /media/{id} · can_setup

curl -X PATCH https://api.lanachat.ai/v1/media/med_5521 \
  -H "Authorization: Bearer $LANACHAT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"access": "paid", "stars": 300, "description": "Beach, golden hour, white bikini"}'

The answer is the updated media. stars is required when access is paid (1 to 100,000), otherwise the API answers 400. The description helps the AI pick the right media; it is never shown to the fan.

Delete a media #

DELETE /media/{id} · can_setup

curl -X DELETE https://api.lanachat.ai/v1/media/med_5521 \
  -H "Authorization: Bearer $LANACHAT_TOKEN"

A media that a script step still uses is refused (409): take it out of the script first.

Folders #

List folders #

GET /media/folders · can_setup

curl "https://api.lanachat.ai/v1/media/folders?creator_id=cr_lea" \
  -H "Authorization: Bearer $LANACHAT_TOKEN"

Create a folder #

POST /media/folders · can_setup

curl -X POST https://api.lanachat.ai/v1/media/folders \
  -H "Authorization: Bearer $LANACHAT_TOKEN" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"creator_id": "cr_lea", "name": "Beach"}'

Rename or move a folder #

PATCH /media/folders/{id} · can_setup

curl -X PATCH https://api.lanachat.ai/v1/media/folders/vf_3 \
  -H "Authorization: Bearer $LANACHAT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "Beach, summer"}'

Delete a folder #

DELETE /media/folders/{id} · can_setup

curl -X DELETE https://api.lanachat.ai/v1/media/folders/vf_3 \
  -H "Authorization: Bearer $LANACHAT_TOKEN"

Only an empty folder can be deleted; otherwise the API answers 409.
