Responses
| 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. |
