# Lokalise (slim)

> Lokalise is a hosted translation management system for software strings, documents and marketing content. Agents reach it through a REST API, the lokalise2 CLI, SDKs in four languages and a hosted MCP server in beta.

Assessment: 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.

## Facts

- Kind: HTTP API · vendor: Lokalise, Inc. · category: Translation · legal entity: Lokalise, Inc. · provenance 98/100
- Endpoint: `https://api.lokalise.com/api2` (HTTP, Streamable HTTP)
- Auth: OAuth or key · pricing: Paid · x402: no · licence: Proprietary service under the Lokalise Master Service Agreement. The CLI and the Node SDK on GitHub are BSD 3-Clause
- Probe metrics: not measured yet (probes haven't run)
- API: REST at `https://api.lokalise.com/api2`, OpenAPI 3.0.3. Default projects (63 paths, 109 operations), projects with branches, and OTA. `GET /v1/audit-logs` sits outside `/api2`
- MCP server: Hosted, in beta. `https://mcp.lokalise.com/mcp/project-management` (22 documented actions) and `https://mcp.lokalise.com/mcp/software-development` (16). OAuth 2 with PKCE and dynamic client registration, or an API token in the `apikey` header
- Credentials: Personal API tokens, read-only or read/write, no expiry, revocable in the profile. OAuth 2 authorisation code grant for the API, with apps registered through Lokalise support and access tokens lasting about 60 minutes
- Rate limits: 6 requests a second per token and per IP, 10 concurrent requests per project. Responses carry `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` (observed on 8 October 2026)
- Pagination: `limit` (default 100, maximum 5,000, 500 on keys) and `page`, with `X-Pagination-*` headers. Cursor paging on keys, translations, projects and glossary terms
- Errors: JSON `error` object with `code` and `message`. Bulk calls return an `errors` array per failed item. 429 on rate limits
- Files: `/files/upload` queues an import and returns a process to poll. `/files/download` covers up to 10,000 key-language pairs, `/files/async-download` the rest
- Translation engines: `automatic_translation` tasks with `translation_engine` of `ai` (default), `deepl` or `google`. Human translation through `/teams/{team_id}/orders`
- SDKs and CLI: `@lokalise/node-api` 16.6.0 (21 September 2026), `python-lokalise-api` 4.3.0 (5 October 2026), Ruby and PHP clients per the docs, and the `lokalise2` CLI v3.1.7 (14 July 2026), BSD 3-Clause

- SLA: 99.5 per cent a calendar month in the Master Service Agreement, with service credits in Annex B. Trial access has no service levels
- Certifications: SOC 2 Type II, ISO 27001 and ISO 27017 per lokalise.com/product/security. Private bug bounty on YesWeHack and a disclosure policy at vdp.lokalise.com
- Data location: Customer data on AWS in EU regions per the security page. Sub-processor list updated 1 August 2026, with locations
- Status: status.lokalise.com on Statuspage, five components (Lokalise.com, API, App, OTA, Messages)
- Prices: Explorer $149 per month (plan); Growth $379 per month (plan); Advanced $1049 per month (plan)

## Before you call it

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`.
