## 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:
- Schema & documentation, 83 against 76
- Agent ergonomics, 82 against 69

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

### Lokalise (BB)

Good for: Agents that manage localisation work, such as adding keys, uploading and exporting string files, keeping a glossary and starting AI or machine translation tasks for a team that already uses Lokalise.

Ahead on:
- Payments & pricing, 30 against 20
- Maintenance & community, 84 against 70

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

Watch for: The Master Service Agreement forbids using the service for benchmarking or competitive analysis

## 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.

**Lokalise.** The REST API has public OpenAPI files, Markdown docs, published rate limits, read-only tokens, scoped OAuth and an audit log endpoint. Access needs a paid plan after a 14-day trial, a person signs up in a browser, and the Master Service Agreement forbids benchmarking. No idempotency keys or deprecation policy 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

### Lokalise

1. Send the token in the `X-Api-Token` header to `https://api.lokalise.com/api2`. OAuth access tokens go in `Authorization: Bearer` and expire after about 60 minutes.
2. Stay under 6 requests a second per token and 10 concurrent requests per project. On 429, back off exponentially and read `X-RateLimit-Reset`.
3. Use a read-only token for reads. A read/write token can call `PUT /projects/{project_id}/empty`, which deletes every key and translation.
4. Use `pagination=cursor` on `/keys` and `/translations`, with `limit` at most 500 on keys, and follow `X-Pagination-Next-Cursor`.
5. Projects above 10,000 key-language pairs need `/files/async-download`. Poll `/processes/{process_id}` for the bundle URL, and do the same after `/files/upload`.
