Get started with our APIs, SDKs, and guides. ## Docs - [Authentication](https://docs.extend.ai/2026-02-09/api-reference/authentication.md): Authenticate Extend API requests with a Bearer token. Create an API key, store it in EXTEND_API_KEY, and send it via the Authorization header or an SDK. - [API Versioning](https://docs.extend.ai/2026-02-09/api-reference/api-versioning.md): Learn how to specify API versions and stay up to date with changes - [Deployments](https://docs.extend.ai/2026-02-09/api-reference/deployments.md): Extend's deployment environments and regional options for meeting data residency and regulatory requirements, including the base URL for each environment. - [API Error Handling](https://docs.extend.ai/2026-02-09/api-reference/error-handling.md): Handle Extend API errors using the structured error object — code, message, retryable, and requestId — with examples and guidance for each status code. ## API Docs -
