For Agents

Upload and download localization files, create branches, and check translation status against a Localizely project from CI or agent workflows.

Install Jentic One Beta

Connect the Localizely API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Localizely API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

View OpenAPI Document

Jentic publishes the only available OpenAPI specification for Localizely API, keeping it validated and agent-ready. Localizely is a translation management platform built around uploading and downloading localization files, with branch and project organisation. The API is intentionally narrow: it covers file upload, file download, branch creation, and translation status checks, designed to be wired into curl scripts and CI pipelines that move translation files in and out of the platform. Authentication is by per-account API token in the X-Api-Token header.

Use Cases

Patterns agents use Localizely API for, with concrete tasks.

★ Translation File CI Pipeline

Engineering teams that ship localised apps want translations pulled into the build at CI time. Localizely's download endpoint returns the latest translation file in the source format, and the status endpoint exposes per-language completion. A CI step calls download for each release and optionally fails the build if a key language is below threshold.

Call GET /v1/projects/{project_id}/files/download for each language in the build, check GET /v1/projects/{project_id}/status, and fail if completion is below the configured threshold.

Source String Upload from Source Control

When developers add new strings to the codebase, those strings need to land in Localizely so translators can pick them up. POST /v1/projects/{project_id}/files/upload accepts the source localization file. Combined with the branch endpoint, teams can isolate new strings on a feature branch until they are ready for production translators.

Call POST /v1/projects/{project_id}/branches/{branch} to create a feature branch then POST /v1/projects/{project_id}/files/upload with the new source strings.

AI Agent Release Gate

An AI agent running release checks can call Localizely through Jentic to confirm translations are complete before approving a deployment. The agent searches Jentic for the status operation, executes it with the project ID, and reports back per-language completion. The API token stays in the Jentic vault.

Use Jentic to call GET /v1/projects/{project_id}/status and report any language below 95% complete to the deployment workflow.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Localizely admin tokens are stored encrypted in the Jentic vault. The X-Api-Token header is injected at execution time, so the raw token never enters agent context, logs, or LLM traces.

Intent-based discovery

Agents search Jentic for intents like 'download translated files' or 'check translation status' and Jentic returns the matching Localizely operation with its input schema, so the agent can run release checks without consulting documentation.

Time to first call

Direct Localizely integration: half a day for auth, file upload and download, and status polling in a CI job. Through Jentic: under 30 minutes to search, load, and execute.

FAQs

Specific to using Localizely API through Jentic.

Why is there no official OpenAPI spec for Localizely API?

Localizely does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Localizely API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Localizely API use?

Localizely uses an API token sent in the X-Api-Token header. The token must belong to a user with the Admin role in the project. Through Jentic, the token is stored encrypted in the vault and injected at execution time, so the raw value never enters agent context.

Can I work on translations in a feature branch instead of the main project?

Yes. POST /v1/projects/{project_id}/branches/{branch} creates a branch inside a project. Subsequent file upload and download calls scoped to that branch keep work-in-progress translations isolated until you merge them back.

What are the rate limits for the Localizely API?

Rate limits are not declared in the spec. Localizely applies plan-level limits at the account level; check your plan or contact support for the exact thresholds.

How do I check translation completion before shipping a release through Jentic?

Search Jentic for 'check translation completion status'. Jentic returns the GET /v1/projects/{project_id}/status operation. Load the schema, supply the project ID, and execute. The response is per-language completion that you can gate the deployment on.

Which file formats can I upload and download?

Localizely supports a range of localization file formats including JSON, YAML, .properties, .strings, and Android XML. The upload and download endpoints accept the file format you configured at the project level on the Localizely dashboard.
