This section provides a quick reference for programmatic APIs: endpoint lists, request parameters, response fields, and the locations of billable usage data.
For examples, key lifecycle management, and console operations, see [Developer](../../developer/index.md) and [Guide · Genesis](../../guides/genesis/index.md).

## Notes

1. This section is a concise summary of the product documentation. The documentation repository does not currently provide a complete, publishable OpenAPI specification that can serve as the sole authoritative specification.
2. Refer to the console's access information and actual API responses for paths, fields, and default values.
3. The Base URL usually already includes the version segment. Do not repeat the version prefix when appending a path. See [Model API · Access Information](model-api.md#access-information).
