Nitro Translate - Online Human Translation Service

# Nitro (NitroTranslate) > Professional human translation as an API. Real native-speaking translators — not > machine translation — in 80+ languages, with no minimum order (translate as little > as one word) and typical turnaround of 2-24 hours. AI agents can order and pay for human translations per request via > the Machine Payments Protocol (MPP), without creating an account or holding a balance. The API base URL is `https://api.nitrotranslate.com/v1`. Full reference, request and response schemas, and the authoritative OpenAPI specification live on the docs site below — prefer those over this file for field-level detail. ## API endpoints - `GET /v1/rates`: Current pricing rates for all supported language pairs (per 1000 characters, USD). - `POST /v1/calculate`: Estimate translation cost per target language before ordering. - `POST /v1/translate`: Submit content for translation and create orders. - `GET /v1/orders`: List orders, newest first by default, with pagination. - `GET /v1/orders/{id}`: Fetch a single order with its full details, including translated text. - `DELETE /v1/orders/{id}`: Remove an order (only while in QUEUE status). - `GET /v1/account`: Retrieve account details (balance and reserved funds). Orders move through `QUEUE` -> `PROGRESS` -> `DONE`. `REVISION` marks a completed order the customer reopened; once rework resumes it reports as `PROGRESS` again. Translated text is delivered asynchronously — poll `GET /v1/orders/{id}` until `status` is `DONE` and read `target_text`. Content is submitted as a `resource` with a MIME `type` of `text/plain`, `text/html`, `application/json`, or `text/x-objcstrings`, plus the payload in `data`. ## Authentication - [Authentication](https://docs.nitrotranslate.com/authentication.md): Three schemes — Basic (API key as username), Bearer (API key as token), and Payment (MPP credential). - [Agentic Flow](https://docs.nitrotranslate.com/agentic-flow.md): Pay per request with the Machine Payments Protoc
