POST/orders/{order}/items/{item}/regenerate

Regenerate Order Item

Regenerates an already completed chunk with new text — the way to fix a typo without redoing the whole order.

Paid: this is a new generation. Your key's token quota is checked first (429 on excess). Do not confuse it with retry, which is free and applies to failed chunks.

Not available for sfx/music.

Required key permission: orders.write.

POSThttps://api.lumean.app/api/public/orders//items//regenerate
  • stringim Pfaderforderlich

    Order UUID — 36 characters shaped like 9f8b2c1a-4d3e-4f5a-8b9c-0d1e2f3a4b5c, not a number.

    Take it from the id field: POST /orders returns it on creation and GET /orders lists it. Someone else’s order will not open with your key — you get a 404.

    Der Wert wird direkt in die Anfragezeile oben eingesetzt.

  • stringim Pfaderforderlich

    Order chunk UUID — 36 characters; neither a number nor a position.

    Take it from an item’s id field: GET /orders/{order}/items returns the list, and the same set sits in items[] of the detailed order response. The chunk’s position is the neighbouring chunk_index field, which does not go into the path.

Anfragekörper

application/jsonerforderlich

Redoing an already finished fragment with new text. The operation is paid — tokens are charged as for a fresh generation.

text is required. The length ceiling is the fragment capacity (max_billable_length from GET …/items/{item}/text); a longer text gets 422 with reason: text_over_capacity. The price is based on the whole new length. Only our own pauses {{pause=2s}} are free: <break/> and any narrator direction in square brackets ([whisper], but also [1], [sic]) are the provider’s syntax — they are billed and take room in the fragment.

New fragment text

  "text": "Новая редакция фрагмента."

texterforderlich

New text for a completed chunk — required. Regenerating an already finished fragment is billed as a new generation (the key's token quota is checked first, 429 on excess).

The chunk was queued for regeneration. This is a paid operation: a fresh token quota is charged.

Felder der Antwort
successerforderlich

Success flag. Branch on the HTTP status code instead: any 2xx response carries true here, while an error comes back in a different shape that need not contain this field at all.

boolean
messageerforderlich

A human-readable note in the account language. Fine to show to a user; do not parse it — the wording changes without notice and is not an error code.

string
dataerforderlich

A new regeneration record with its own id. The operation is paid: tokens are charged again, and the previous version stays in the history.

OrderItemOrderItem
iderforderlich

Chunk UUID. Use it in /orders/{order}/items/{item}/… paths.

string
order_iderforderlich

UUID of the order this chunk belongs to.

string
item_typeerforderlich

What the record is: chunk is an original fragment, retry a free re-run of a failed one, regeneration a paid redo of a finished one.

Retries and regenerations are separate records sharing the same chunk_index: the full attempt history is kept, and the last one is what the result plays.

string
chunk_indexerforderlich

Zero-based position of the fragment within the order. It defines the order in which the final file is assembled.

darf null sein
integer
paragraph_indexerforderlich

The paragraph this fragment belongs to — filled in only for the original fragments of a paragraph-mode order. It is null both in ordinary mode and on retry or regeneration records: those carry no paragraph link of their own and inherit it from the parent fragment via parent_item_id. The mode is switched on by the generation_mode key in the order's config_override.

string
parent_item_iderforderlich

UUID of the source chunk — present on retry and regeneration records. null on an original chunk.

string
original_text_lengtherforderlich

Length of the text the fragment was created with. It is the ceiling for text in regenerate.

integer
current_text_lengtherforderlich

Length of the fragment’s current text: after a regeneration it differs from original_text_length.

integer
price_unitserforderlich

Cost of the fragment in tokens — not money. The monetary amount lives on the order itself, in its own price_units field (LMC there, tokens here; the names match, the units do not).

integer
consumed_unitserforderlich

How many tokens were actually charged for this fragment. Zero while the fragment is unfinished.

integer
remaining_lockederforderlich

How many tokens are still reserved for the fragment. Drops to zero once the fragment finishes or is cancelled.

integer
statuserforderlich

Fragment state: pending waits for a worker, processing is in flight, completed is done, failed hit a technical error, and policy_flagged was rejected by the content policy.

The difference between the last two dictates the fix: failed is cured by retrying as is, whereas policy_flagged requires rewording — retrying the same text is rejected again.

string
result_fileerforderlich

The finished fragment’s file: an absolute path, or a structure carrying path and size. Download it via POST /storage/url, same as order files. null until the fragment is ready.

darf null sein
object | string | null
duration_mserforderlich

Duration of the produced audio in milliseconds — the length of the recording, not the generation time. null for non-audio tasks.

darf null sein
integer
attempt_numbererforderlich

Attempt number for this fragment, starting at 1. It grows with every retry.

integer
can_retryerforderlich

Whether a free retry is allowed right now. It already accounts for status, task type and exhausted attempts, so you need not re-check the conditions.

boolean
can_regenerateerforderlich

Whether a paid regeneration is allowed right now. Available for finished fragments only.

boolean
created_aterforderlich

When the fragment was created, ISO 8601.

darf null seindate-time
string
updated_aterforderlich

When the fragment last changed, ISO 8601.

darf null seindate-time
string
failure_reasonoptional

Machine-readable failure reason — present only on failed and policy_flagged. Everything else gets null.

darf null sein
string
400

Any other refusal without a machine code (rare): the reason is only in message. Refusals with a reason come as 402/422/503.

Beispiel für den Body
{
  "success": false,
  "message": "The operation could not be completed."
}
Felder der Antwort
successerforderlich

Always false in error responses.

boolean
messageerforderlich

The reason for the rejection in words, in the account language. Meant for display; do not branch on it, the wording changes.

string
errorserforderlich

A per-field breakdown — present only on validation errors (422): the key names a request field, the value lists the complaints about it. Other codes send null, since there is nothing to break down and the whole reason is in message.

darf null sein

401

The key is missing, unknown, disabled or expired.

Machine-readable reason of a business refusal (for example, input_expired, insufficient_balance). Branch on it, not on the message text.

string
403

The key lacks the required permission, or the object belongs to another user.

Felder der Antwort
messageerforderlich

Error overview.

string
422

The required text field is missing, or regeneration is not possible (reason): invalid_status — the chunk is not completed, text_over_capacity, text_not_voiceable, content_blocked, generative_not_supported (sfx/music), retry_config_outdated — the order's settings no longer pass the service's current schema, create a new order.
