HTTP status codes

Code	Description
200	Default HTTP response for both success and many business errors. Only outer JSON code 0 indicates success or asynchronous acceptance; inspect data for the result.
429	Execution admission rate limit; honor Retry-After when present.
503	Execution admission is temporarily unavailable; honor Retry-After when present.
Opt-in	X-Nexscope-Http-Status: semantic maps controller-handled business errors to HTTP status on run and task routes. Pre-authentication failures, such as a missing or invalid API key (code 11209, including an incomplete or corrupted copy) or an expired website login session (code 12001), may still return HTTP 200 before this mapping. Always check the outer JSON code; malformed requests and infrastructure failures may also return non-200 HTTP responses.

Step 1 of 2 · Connect your MCP client

MCP

V2 recommended

Connect remote agents through the standard MCP 2025-11-25 Streamable HTTP endpoint. Use OAuth 2.1 Authorization Code with PKCE, or an API key for compatibility.

POST https://api.nexscope.ai/mcp
MCP-Protocol-Version: 2025-11-25
Content-Type: application/json

Authentication

OAuth clients request the mcp:tools scope. The endpoint's 401 response advertises protected-resource metadata for authorization discovery.

AI Guide

Question

What can the Nano Banana Image Generation API do?

AI answer

Nano Banana accepts a request to generate ecommerce images from text or reference images. It runs asynchronously: the immediate response identifies a task, and the shown example is pending with no image result. Retrieve the task result before using any media.

Returned field	What it tells you
`code`	`0` means the request was accepted or successful; a nonzero value is a platform error.
`data.taskId`	Identifies the task to retrieve later.
`data.status`	Reports the task state; the example shows `PENDING`.
`data.result`	The example is `null`, so this response does not establish that an image is ready.
`traceId`	Provides a trace value when present for troubleshooting.

Request a square product hero image from a reference photo, then retain data.taskId for retrieval.
- Prompt example: “I am preparing product creative for an online listing. Could you request a square product hero image from a reference photo, then retain data.taskId for retrieval? Ask me for required source images or text, and show the finished result only after the task completes.”
Submit a text-only request for a lifestyle scene and check data.status before using its result.
- Prompt example: “I am preparing product creative for an online listing. Could you submit a text-only request for a lifestyle scene and check data.status before using its result? Ask me for required source images or text, and show the finished result only after the task completes.”
Request several visual variations for a campaign and wait for the task result before reviewing them.
- Prompt example: “I am preparing product creative for an online listing. Could you request several visual variations for a campaign and wait for the task result before reviewing them? Ask me for required source images or text, and show the finished result only after the task completes.”
