Common Error Codes
In addition to API-specific error codes, the following error codes may be returned by any API endpoint:
Plan Error Codes (PlanErrorEnum)
These errors are related to your subscription plan's credit and capacity limits. Your API usage consumes credits and counts against your plan's capacity.
| Error Code | Description |

capacity_not_enough |
Storage capacity exceeded. Delete unused documents or upgrade your plan. |
app_count_not_enough |
Maximum number of apps allowed by your plan has been reached. |
member_count_not_enough |

System Error Codes (SystemErrorEnum)
These are general system-level errors that may occur during API operations.
| Error Code | Description |

Rate Limiting
API calls are subject to rate limits based on your subscription plan. HTTP 429 status code will be returned when limits are exceeded.
Getting Started
Basic Workflow
- Obtain an API Key from the ChatDOC Studio console
- Configure environment variables
- Review the module's documentation and examples
- Upload documents (for Chat/Agent/RAG/Extract Apps) using the Uploads API
- Immediately create your app or task using the upload IDs (processing is auto-triggered when referenced)
- Wait for the app or task to become ready before using downstream features
- Integrate into your application
Quick Start Examples
PDF Parser: Upload and parse → Get JSON/Markdown/Excel
Chat App: Upload documents → Create Chat App → Send messages
Agent App: Upload required documents → Create Agent task with documents grouped by slot label → Poll status → Get final result
RAG App: Upload documents → Create RAG App → Query content
Extract App: Create Extract App with schema → Upload document → Get extracted data
