## Which one, for what

### Amazon Translate (B)

Good for: Operators already on AWS who want translation inside IAM and CloudTrail, with S3 batch jobs and terminology files.

Ahead on:
- Reliability, 90 against 84
- Schema & documentation, 90 against 76
- Agent ergonomics, 80 against 69

Watch for: AWS may store and use text to improve Amazon AI services unless the organisation sets an opt-out policy

### 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 25
- Transparency & trust, 81 against 69

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

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

## Verdicts

**Amazon Translate.** IAM policies scope access per action and resource, with a `TranslateReadOnly` managed policy, and CloudTrail logs each call. AWS may store and use text to improve Amazon AI services unless the organisation sets an opt-out policy.

**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

### Amazon Translate

1. Chunk real-time text under 10,000 bytes, not characters, so multibyte scripts fit less per call
2. Pass `SourceLanguageCode` auto to detect the source language, and handle `DetectedLanguageLowConfidenceException`
3. Read `AppliedSettings` in the response, since unsupported formality or profanity settings are dropped without an error
4. Retry `TooManyRequestsException` with backoff, which the AWS SDKs do by default
5. Set the AI services opt-out policy before sending private text

### 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`.
