Verdicts

Lara Translate API

Glossaries, translation memories, styles and instructions on every translate call. Texts may be used for model improvement unless a request sets noTrace.

Smartcat

Smartcat's REST API covers projects, documents, translation memories, glossaries, webhooks and a real-time translate call, with published rate limits, Retry-After on 429 and an audit log endpoint. Keys are account-wide with no documented scopes, the status page lists two incidents of an hour or more in 90 days, and API access is listed only from the $60,000-a-year Anticipate plan.

Before you call either

Lara Translate API

  1. Set noTrace on every request that carries private text, since storage for model improvement is the default
  2. Leave reasoning off unless the text needs it. It moves the call to Lara Think at $2,499 per million characters
  3. Resolve glossary and memory names to gls_* and mem_* IDs with the list tools before translating
  4. Send one target language per translate call
  5. Merge short documents, since each file bills at least 20,000 characters

Smartcat

  1. Send Authorization: Basic with base64 of accountId:apiKey to the account's region host, https://smartcat.ai, https://us.smartcat.ai or https://ea.smartcat.ai.
  2. On 429, wait the seconds in Retry-After before retrying. The 429 itself carries no x-rate-limit-* headers.
  3. Create a smart translation profile in the web app first and pass its ID as profile to smartTranslation/translate.
  4. Store each requestUid and look charges up later with smartTranslation/charges, since the translate response doesn't include the cost.
  5. Treat callbacks as hints and poll project, document or export status as a fallback, because failed deliveries are dropped after the last retry.
