import Endpoint from '../../../components/Endpoint.astro';

<Endpoint method="GET" path="/api/developer/v1/knowledge" title="List knowledge sources" />
<Endpoint method="POST" path="/api/developer/v1/knowledge" title="Create a text knowledge source" />
<Endpoint method="GET" path="/api/developer/v1/knowledge/{knowledge_id}" title="Get knowledge details" />
<Endpoint method="PUT" path="/api/developer/v1/knowledge/{knowledge_id}" title="Update knowledge" />
<Endpoint method="DELETE" path="/api/developer/v1/knowledge/{knowledge_id}" title="Delete knowledge" />

Knowledge creation accepts `name`, `text`, and optional `is_active`. Attach the returned knowledge ID to an agent, then test retrieval with real customer phrasing.

<Endpoint method="GET" path="/api/developer/v1/tts-config" title="List valid TTS configuration" />
<Endpoint method="POST" path="/api/developer/v1/tts/generate" title="Generate speech" />

Use the configuration endpoint rather than hardcoding provider voices. Voice availability and supported languages can vary by provider and account.
