NanoBananaPro for DeepSeek Harness

dsh-nanobananapro adds native image and video generation to DeepSeek Harness through the NanoBananaPro public API. It uses a user-owned NanoBananaPro API key; provider, billing, database, and storage credentials stay on the NanoBananaPro service.

Tools:

• nanobananapro_generate_image
• nanobananapro_generate_video
• nanobananapro_get_task
• nanobananapro_get_balance
• nanobananapro_account_help

中文说明

Account, API key, and recharge

1. Sign in at https://api.bananapro.site.

2. Buy API credits at https://api.bananapro.site/api-pricing.

3. Create an API key at https://api.bananapro.site/api-keys.

4. Keep the key private. Set it in the environment that launches Harness:

   export NANOBANANAPRO_API_KEY='sk-...'

5. Restart Harness and ask it to call nanobananapro_get_balance.

NanoBananaPro has separate web-playground and API wallets. This plugin consumes the API wallet, so purchasing ordinary web credits does not fund API calls. The balance tool returns both values and the correct recharge link.

Official API documentation: https://api.bananapro.site/api-docs

Install

npx -y @deepseek-ai/dsh plugin --profile web add dsh-nanobananapro
npx -y @deepseek-ai/dsh --profile web --dump-config
npx -y @deepseek-ai/dsh web --profile web

The config dump should contain a nanobananapro bundle layer.

To install a cloned checkout instead:

npx -y @deepseek-ai/dsh plugin --profile web add .

Try it

Check my NanoBananaPro API balance. Then create a 16:9, 2K cinematic hero
image of a transparent running shoe on chrome. Wait for the result.

Use NanoBananaPro Veo 3 Fast to create a cinematic 16:9 video of a yellow paper
airplane gliding through a clean blue studio. Wait for the final video link.

Reference media must be reachable through public HTTPS URLs. The plugin does not upload local files; upload them to a public object store or the product UI first, then pass the resulting URL.

Safety and billing behavior

• Paid image and video tools ask for approval by default.
• The API key is resolved through Harness credentials and is never a model tool argument.
• Every paid submission sends an Idempotency-Key; automatic retries reuse it.
• Retryable 429 and 5xx responses are retried with bounded backoff.
• Cancellation aborts requests and foreground polling.
• 401 errors point to API-key management; 402 errors point to API recharge.
• If the foreground wait expires, the task is returned with timed_out: true. Continue with nanobananapro_get_task; do not submit a duplicate request.

Configuration

Override the bundle in $DSH_HOME/profiles/web/cordis.patch.yml only when needed:

- id: nanobananapro
  config:
    apiBaseUrl: https://gateway.bananapro.site
    apiKeyEnv: NANOBANANAPRO_API_KEY
    requestTimeoutMs: 30000
    pollIntervalMs: 3000
    imageWaitTimeoutMs: 300000
    videoWaitTimeoutMs: 900000
    maxRetries: 2
    retryDelayMs: 500
    requireApproval: true
    allowLocalHttp: false

Harness config rows are replaced as a whole, so retain every setting when overriding the row. Disable requireApproval only for a trusted automation with an intentional spending limit.

Validate

npm run check
npm test
npm run pack:check

The package ships plain JavaScript and does not need an install-time build script.
