Provide via

GRSAI_API_KEY

environment variable.

Troubleshooting

Symptom	Resolution
`Error: No API key provided.`	Set `GRSAI_API_KEY` env var or pass `--api-key`
`Error: Image not found:`	Wrong path or unreadable file; verify the path exists
HTTP 401	Wrong or expired API key
`Unexpected response format`	API error; check prompt for policy violations
`uv: command not found`	Install: `curl -LsSf https://astral.sh/uv/install.sh \| sh` , then restart terminal

For transient errors (HTTP 429, network timeouts), the script retries automatically up to 3 times. If retries are exhausted, surface the error to the user.

Output

Print the response to stdout. Optionally save to file with

--output

. Do not pipe output unless the user asks.

Examples

bash

uv run scripts/query_gemini.py --prompt "Explain the difference between TCP and UDP in simple terms"

bash

uv run scripts/query_gemini.py --prompt "What objects are in this image?" --image "photo.jpg" --output "analysis.md"
