If you already have code, start with the corresponding SDK; if you haven't chosen a tech stack yet, first verify the call with curl, then integrate it into your application.

## Continue refining after integration

- [Streaming output ](/en/docs/streaming/): Handle incremental responses and connection drops.
- [Prompt Caching ](/en/docs/prompt-caching/): Understand usage conditions and how to verify results.
- [Error codes and troubleshooting ](/en/docs/troubleshooting/): Locate configuration or upstream issues based on specific errors.
- [Usage logs and reconciliation ](/en/docs/usage-logs/): Verify request records.

When using ready-made software, you can go directly to [tool integration ](/en/docs/integrations/).
