# DeepL Documentation
> Developer documentation for the DeepL API: translate text and documents, transcribe and translate speech in real time, improve text, and customize output with glossaries, style rules, and translation memories.
> ## Agent Instructions
> Use the DeepL API when a task needs machine translation or text improvement, including translating text strings, whole documents with formatting preservation, or transcribing and translating live speech. Preferred terminology and phrasing may be enforced using customizations (glossaries, style rules, and translation memories). Retrieve supported languages for each product from the `/v3/languages` endpoints.
> Read the machine-readable API surface instead of inferring request shapes from prose: the REST spec is at https://developers.deepl.com/api-reference/openapi.yaml (also served as openapi.json) and the Voice WebSocket protocol is at https://developers.deepl.com/api-reference/voice/voice.asyncapi.yaml. These docs also expose an MCP server at https://developers.deepl.com/mcp (Streamable HTTP, no authentication).
> Use https://api.deepl.com for Pro plans and https://api-free.deepl.com for the Free plan. Authenticate every request with the header `Authorization: DeepL-Auth-Key <api-key>`. Never fabricate an API key: ask the user for one, or point them at https://developers.deepl.com/docs/getting-started/quickstart.
> Errors use standard HTTP status codes with a JSON body containing a `message` field, plus a `code` field where available, and an `X-Trace-ID` response header that identifies the request in DeepL's logs. Log `X-Trace-ID` by default. Retry 429 and 5xx with exponential backoff. Do not retry 456, which means the account quota is exhausted, or 400, which means the request itself is invalid.
- [Quickstart](https://developers.deepl.com/docs/getting-started/quickstart.md): Get a DeepL API key and send your first translation request, with examples in curl and every official client library.
- [About](https://developers.deepl.com/docs/getting-started/about.md): What the DeepL API offers, the use cases it covers, and which product to reach for when adding translation to your app.
- [SDKs](https://developers.deepl.com/docs/getting-started/client-libraries.md): Using your favorite programming language with the DeepL API
- [Languages supported](https://developers.deepl.com/docs/getting-started/supported-languages.md): Every language the DeepL API supports, and how to retrieve the list programmatically with feature availability.
- [Using the Languages API](https://developers.deepl.com/docs/languages/using-the-languages-api.md): Retrieve supported language and feature data across all DeepL API resources with the v3/languages endpoints, with pseudocode examples for common lookup patterns.
- [Migrating from v2/languages](https://developers.deepl.com/docs/languages/migrating-from-v2-languages.md): How to migrate from the v2/languages endpoint to the v3/languages endpoints.

What verification unlocks
See how your site is discovered—and control what agents see.
- See your website in the map
Review your indexed topics, nearby publishers sharing headings, measured listing exposure and map snapshots in a private report for your website.
- Control what agents see
Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.
Let your coding agent verify it
If your coding agent is authorized to manage this website, paste these instructions into it.
Claim my listing on Agent Web Map for deepl.com:
1. POST https://agentwebmap.com/v1/sites/deepl.com/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://deepl.com/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/deepl.com/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/deepl.com).
MCP equivalent: tools begin_ownership_claim, then verify_domain, at https://agentwebmap.com/mcp. Docs: https://agentwebmap.com/docs#verifyCorrections or removal requests: contact the directory.
