## Which one, for what

### Lingvanex Translation API (F)

Good for: Bulk translation of non-sensitive text where price per character matters most, or buyers who want an on-premise server later.

Watch for: Product pages disagree on bulk and on-premise prices

### 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:
- Reliability, 84 against 40
- Schema & documentation, 76 against 48
- Agent ergonomics, 69 against 50
- Security & auth, 73 against 37
- Payments & pricing, 30 against 15
- Maintenance & community, 84 against 6
- Transparency & trust, 81 against 48

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

**Lingvanex Translation API.** $5 per million characters list price. Product pages disagree on bulk and on-premise prices.

**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

### Lingvanex Translation API

1. Call the https:// server, not the http:// one the spec also lists
2. Send `platform` as api on every call, since the spec marks it required
3. Use locale codes such as en_GB and de_DE, not two-letter codes
4. Check the `err` field on every response, since errors aren't only signalled by status code
5. Send an array in `data` to translate several strings in one call

### 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`.
