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 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. |
