Run an API

Generate ecommerce images with the Nano Banana 2 model.

Slug	`banana-2-image-generation`
Headers	`Authorization: Bearer nk-...` `Content-Type: application/json`
Request body	API-specific JSON object.
Response body	Platform envelope: code, msg, data, ts, time, cost, traceId. Inspect data.status for asynchronous completion.

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 API key (code 11209), 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.
