Create project Read docs

✅ Redis L2 cache ✅ Bulk endpoint ✅ Async jobs ✅ Quotas & Plans

Bulk = instant win

Translate dozens or thousands of keys in one request. Dedupe + Redis pipeline = minimal latency.

Cache-first performance

Redis L2 + Mongo L3 give stable p95 and reduce translation service load dramatically.

UGC-ready

Async queue for peaks, write-behind storage, rate limits, quotas, and audit logs.

How it works

Create a project in Console and get an API key.
Call the API from your app (single or bulk).
Manage overrides and quotas from the console.

Quick Start (60 seconds)

1) Create a project in Console → copy API key

2) Translate:

curl -sS -X POST https://translate.multilang.store/v1/translate \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "scope":"your-scope",
    "key":"ui:hero:title",
    "text":"Welcome to Corporate Multilang",
    "source_lang":"auto",
    "target_lang":"ru",
    "format":"text"
  }'

Bulk:

curl -sS -X POST https://translate.multilang.store/v1/translate/bulk \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "scope":"your-scope",
    "items":[
      {"key":"ui:hero:title","text":"Welcome","target_lang":"ru"},
      {"key":"ui:hero:subtitle","text":"Built for SaaS","target_lang":"ru"}
    ]
  }'

FAQ

What is a unit?

Single request = 1 unit. Bulk = min(10, items) units.

What happens if I exceed quota?

API returns HTTP 402 with quota headers. Upgrade plan or reset quota via admin.

Do you support human overrides?

Yes. Overrides have priority over machine translations and update Redis instantly.
