## 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 78
- Agent ergonomics, 82 against 69
- Security & auth, 75 against 68

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

### Crowdin (B)

Good for: Teams that keep product strings and files in Crowdin and want an agent to upload sources, check progress, apply pre-translation, manage glossaries and pull builds.

Ahead on:
- Payments & pricing, 30 against 20
- Maintenance & community, 82 against 70

Watch for: The terms forbid accessing the service to monitor availability, performance or functionality, or for benchmarking, without Crowdin's prior written consent

## 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.

**Crowdin.** The REST API has a public OpenAPI document with 374 operations, and tokens can be limited by scope, access level and project. Translation runs inside Crowdin projects and connected engines, so it is not a stateless per-character translation API. No Retry-After guidance, idempotency keys or SLA were found in the reviewed documentation.

## 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

### Crowdin

1. Send `Authorization: Bearer <token>` to `https://api.crowdin.com/api/v2`. Crowdin Enterprise uses `https://<organization_domain>.api.crowdin.com/api/v2`
2. Use the MCP V2 endpoint `https://mcp.crowdin.com/v2/mcp` and set `crowdin-tool-sets`, because the server loads all 33 tool sets by default
3. Set `crowdin-read-only: true` on the MCP connection for exploration. It exposes only list and get tools
4. Keep to 20 concurrent requests an account across all tokens, and add your own backoff on 429
5. Upload a file to `/storages` first, then pass the `storageId` to the add-file call. Builds, exports and reports are asynchronous and need a status poll
6. `/mts/{mtId}/translations` takes at most 100 strings a call and needs the `mt` scope and a configured engine
