Lara Translate API vs Lokalise

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.

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.

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

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.
