Paste your key, type a message
like kya kar rahe ho bhai, and hit send.

Why it's different

Most translation APIs choke on how India actually texts. This one was built for it.

THE SPECIALTY

Hinglish & Indian languages, natively

Romanized Hindi like "kal milte hain" is detected and translated with the slang, tone, and code-switching intact — not mangled into nonsense. Real understanding of how Indians actually chat.

scene kya hai→ what's up

bahut badhiya→ awesome

पैसे भेज दो→ send money

Blazing fast

Sub-100ms compute on GPU; ~2ms on cache hits. Built for real-time chat, not batch jobs.

Dead simple

One key in your call metadata. No SDK lock-in, no setup ceremony. Ship it in an afternoon.

Self-hostable

Run it on your own infra when you need to. MIT-licensed model — your data stays yours.

Get your API key

One active key per account — signing in again regenerates your key and replaces any existing one.

Request body (JSON)

Field	Type	Notes
text	string	Required. Max 200 chars — longer is rejected with a 400.
tgt_lang	string	Required. Target code (see languages below).
src_lang	string	Optional. `""` = auto-detect. Pass `"hi"` for short Hinglish.

Response (200)

Field	Type	Notes
translated_text	string	The translation.
detected_src	string	Resolved source language code.
cached	bool	`true` if served from cache (~2ms).
latency_ms	int	Server-side engine time.

Errors — all `{"error": "…"}`

400	Empty / too-long text, or unsupported `tgt_lang`.
401	Missing or invalid API key.
402	Monthly quota exhausted (also returns `used`/`cap`).
429	Rate limit hit — back off by the `retry-after` header (seconds).
503	Backend busy / auth unreachable — retry with backoff.

Rate limit & cold starts

Free tier: 10 requests / min per key (fixed window). The API scales to zero when idle, so the first request after ~5 idle minutes cold-starts (~50s) — set a client timeout of ≥ 90s and don't retry-storm it.

Languages (tgt_lang)
