Text Language

Overview

Text Language works by analyzing the text and comparing it to a database of languages and ai models. It uses advanced algorithms to detect the language of the text and returns the language.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

Parameters

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

{
  "status": "ok",
  "error": null,
  "data": {
    "language": "french",
    "iso": "fr"
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Use cases

Localized Helpdesk Queuing

Helpdesk software inspects inbound contact messages to route each ticket to an agent fluent in the detected language.

User Review Indexing

When customers submit feedback across regional app stores, marketplaces tag each comment with its ISO code for localized sentiment tracking.

Forum Post Moderation

Community platforms check new discussion submissions to assign posts to regional moderators based on the returned language name.

Speech Engine Selection

Before generating synthetic audio, narration tools check input snippets to select the voice model matching the detected ISO code.

Other ways to use Text Language

Set up Text Language on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
