Quoting is free. The price is per new target language: adding a language to an existing project charges only for the language being added.

​

Header

accessKey · string · required

Your API key. See Authentication.

​

Path

projectId · string · required

The project identifier. The source must already be ready.

​

Body

settingsVersion · number

Optional. If present and different from the current version, the request is rejected with 47109.

targetLanguages · array · required

The languages to price. Must not be empty.

​

Response

quoteId · string | null

Pass this to the generation endpoint. null when state is ALL_TARGETS_EXIST.

projectId · string

Project identifier.

settingsVersion · number

Draft version the quote was based on.

sourceDurationMs · string

Source duration, as a string.

planKey · string

The plan the rate came from.

rateVersion · string

Rate version label.

charactersPerMinutePerLanguage · number

The rate applied, per language.

perTargetCharacters · string | null

Characters per new language, as a string.

requestedLanguages · array

The languages you asked for.

existingTargets · array

Languages that already exist for this source: { language, characters, targetId, state, action }.

newTargets · array

Languages that will be created and charged.

targets · array

The languages a submission would create and reserve now. This field is the same content as newTargets, kept under its pre-decision name — it is not a union of existingTargets and newTargets, and it excludes languages the project already carries.

totalCharacters · string

Total charge, as a string. "0" for ALL_TARGETS_EXIST.

availableCharacters · string | null

Available balance, as a string.

estimatedRemainingCharacters · string | null

Projected balance, as a string.

balanceState · string | null

AVAILABLE or LEDGER_UNAVAILABLE for this response, or null. It describes the balance fields of this response only; a LEDGER_UNAVAILABLE value means availableCharacters and estimatedRemainingCharacters are null rather than guessed.

state · string

ACTIVE, ALL_TARGETS_EXIST or CHANGED.

expiresAt · string | null

When the quote expires (time to live quoteTtlSeconds, normally 600 seconds).

ALL_TARGETS_EXIST is a successful quote, not an error. quoteId is null and totalCharacters is "0" — read existingTargets and never call the generation endpoint with a null quoteId. All Characters values are JSON strings; convert them before comparing.
