## Which one, for what

### Azure Translator (BB)

Good for: Azure shops that want cheap NMT at volume, Entra ID auth and a choice of an LLM per request for tone and gender.

Ahead on:
- Reliability, 83 against 56
- Schema & documentation, 83 against 67
- Agent ergonomics, 82 against 57
- Security & auth, 75 against 42

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: The 2026-06-06 schema breaks v3.0 clients and drops BreakSentence and dictionary lookups from the spec

### Smartcat (C)

Good for: Agents that run translation projects for a team already on a Smartcat Anticipate or higher plan, such as uploading documents, applying translation memories and glossaries, exporting results and calling real-time translation from an app.

Ahead on:
- Payments & pricing, 25 against 20

Also in its favour:
- Free to start without a card

Watch for: API access is listed only from the Anticipate plan, $60,000 a year per the help centre, while the pricing FAQ says the trial includes it

## Verdicts

**Azure Translator.** $10 per million characters pay as you go, 2 million free a month on F0, commitment overage down to $5.50. The 2026-06-06 schema breaks v3.0 clients and drops BreakSentence and dictionary lookups from the spec.

**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

### Azure Translator

1. Send `Ocp-Apim-Subscription-Region` with the key for a regional resource
2. Pin `api-version=3.0` until your client handles the 2026-06-06 `inputs` and `value` shape
3. Batch up to 1,000 strings a call rather than one call per string
4. Spread load across the hour, since the character caps are hourly and bursts get 429
5. Treat 403001 as the free quota running out, not a permissions error

### 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.
