Reference

The interfaces Orca Agent Engine exposes - the CLI, TypeScript, Python, and Go SDKs, and their API specifications.

Use the ork command-line interface, the TypeScript, Python, or Go SDK, or the registry HTTP API to work with Agent Engine. The CLI also manages StreamNative Cloud streaming resources such as connections, functions, and connectors; the SDKs provide typed clients for application code.

Credential names are not interchangeable across clients. The CLI reads ORCA_REGISTRY_URL and either ORCA_API_KEY for x-api-key or ORCA_ACCESS_TOKEN for Bearer authentication. All three SDKs use ORCA_BASE_URL; TypeScript and Python send their ORCA_API_KEY setting as Bearer, while Go sends it as x-api-key. Go also accepts ORCA_ACCESS_TOKEN for Bearer authentication.
