Common Status Codes

These status codes apply to all parse endpoints.
Status CodeNameDescriptionWhat to Do
401UnauthorizedMissing or invalid API key.Check that your apikey header is present and contains a valid API key.
402Payment RequiredYour account does not have enough credits to complete processing.If you have multiple accounts, make sure you’re using the correct API key. Add more credits to your account.
429Too Many RequestsRate limit exceeded.Wait before retrying. Reduce request frequency and implement exponential backoff.

​
ADE Parse and ADE Parse Jobs

This section covers errors for both ADE Parse and ADE Parse Jobs.

​
Status Codes

Status CodeNameDescriptionWhat to Do
200SuccessADE Parse: Document parsed successfully and returned immediately.Continue with normal operations.
202AcceptedADE Parse Jobs: Job created successfully and queued for processing.Use the returned job_id to check job status. See Get Async Job Status.
206Partial ContentADE Parse: Document parsed but some pages failed during processing.Review the failed_pages field in the metadata. See Status 206.
400Bad RequestInvalid request due to document download failure, unsupported model version, or Zero Data Retention constraints.Review error message for specific issue. See Status 400.
422Unprocessable EntityInput validation failed.Review your request parameters. See Status 422.
500Internal Server ErrorADE Parse: All pages failed to process.
ADE Parse Jobs: Server error during job creation or enqueuing.		Retry. If the issue persists, contact support@landing.ai. See Status 500.
504Gateway TimeoutADE Parse: Request processing exceeded the timeout limit (475 seconds).Reduce document size or number of pages. See Status 504.

​
Status 206: Partial Content

Applies to: ADE Parse only This response occurs when the document was parsed successfully but some pages failed during processing. The API returns a 206 status code with the parsed content for successful pages and a failed_pages array in the metadata that lists which pages failed. Because the API returns at least partial results, the API call consumes credits. What to do:
  • Review the failed_pages field in the metadata to identify which pages failed.
  • Check if the failed pages are corrupted or have unusual formatting.
  • If the issue persists with specific pages, contact support@landing.ai.

​
Status 400: Bad Request

This status code indicates invalid request parameters or client-side errors. Review the specific error message to identify the issue.

​
Error: Failed to download document from URL

This error occurs when the API cannot download the document from the provided document_url. Error message: 
Failed to download document from URL: {error_details}
What to do:
  • Verify the URL is accessible and returns valid content.
  • Check network connectivity and URL permissions.
  • Ensure the URL points to a supported document type.

​
Error: Unsupported model

This error occurs when an invalid or unsupported model version is specified. Error message: 
Unsupported model: {version}
What to do:
  • Check the API documentation for supported model versions.
  • If you don’t specify a version, the API uses the latest version by default.
  • Verify the model version string is formatted correctly.

​
Error: output_save_url must be present if zeroDataRetention is enabled

Applies to: ADE Parse Jobs only This error occurs when Zero Data Retention (ZDR) is enabled but no output save URL is provided. Error message: 
output_save_url must be present if zeroDataRetention is enabled
What to do: When using Zero Data Retention (ZDR), you must provide an output_save_url where the parsed results will be saved. The results will not be returned in the API response when ZDR is enabled.

​
Error: Only document_url is accepted if zeroDataRetention is enabled

Applies to: ADE Parse Jobs only This error occurs when Zero Data Retention (ZDR) is enabled but a document file is uploaded instead of providing a URL. Error message: 
Only document_url is accepted if zeroDataRetention is enabled
What to do: When using Zero Data Retention (ZDR), you must use the document_url parameter to provide a URL to your document. Direct file uploads via the document parameter are not supported with ZDR.

​
Status 422: Unprocessable Entity

This status code indicates input validation failures. Review the error message and adjust your request parameters.

​
Error: Cannot provide both ‘document’ and ‘document_url’

This error occurs when both a document file and a URL to a document are provided in the same request. Error message: 
Cannot provide both 'document' and 'document_url'. Please provide only one.
What to do: Choose one input method:
  • Provide a document file using the document parameter, OR
  • Provide a URL to a document using the document_url parameter.

​
Error: Must provide either ‘document’ or ‘document_url’

This error occurs when your request does not include either the document or document_url parameter. Error message: 
Must provide either 'document' or 'document_url'.
What to do: Add one of these parameters to your request:
  • Use the document parameter to upload a document file, OR
  • Use the document_url parameter to provide a URL to a document.

​
Error: Invalid URL format

This error occurs when the document_url parameter contains an invalid URL. Error message: 
Invalid URL format: {url}
What to do:
  • Verify the URL is properly formatted with a valid protocol (http:// or https://).
  • Check for typos or missing characters in the URL.
  • Ensure the URL is properly encoded if it contains special characters.

​
Error: PDF must not exceed X pages

This error occurs when the PDF page count exceeds your account’s page limit. Error message: 
PDF must not exceed {limit} pages.
What to do:
  • Reduce the PDF page count. To see the maximum number of pages allowed, go to Rate Limits.
  • Consider using the ADE Parse Jobs API, which allows you to process longer documents.

​
Error: PDF contains zero pages

This error occurs when the PDF file has no pages. Error message: 
PDF contains zero pages. Please provide a PDF with at least one page.
What to do: Use a valid PDF file that contains at least one page of content.

​
Error: Failed to open or read PDF

This error occurs when the PDF file is corrupted or cannot be opened. Error message: 
Failed to read PDF document: {error_details}
or 
Failed to open PDF. Ensure it is a valid PDF file.
What to do:
  • Use a valid, non-corrupted PDF file.

​
Error: Unsupported format

This error occurs when the uploaded file format is not supported. Error message: 
Unsupported format: {mime_type} ({filename}). Supported formats: {supported_formats}
What to do:
  • Check the list of supported file types.
  • Convert your document to a supported format before uploading.
  • Verify the file extension matches the actual file content.

​
Status 500: Internal Server Error

This error indicates a server-side failure. ADE Parse: All pages in the document failed to process. Error message: 
Failed to process the document
What to do:
  • Retry the request.
  • Check if the document has unusual formatting or corrupted content.
  • Try processing individual pages if the document is very large.
  • If the error persists, contact support@landing.ai.
ADE Parse Jobs: Server error during job creation or processing. Error message: 
Failed to enqueue job for processing
or

Get Async Job Status

Use this section to troubleshoot issues encountered when calling the Get Async Job Status API.

​
Status Codes

Status CodeNameDescriptionWhat to Do
200SuccessJob status retrieved successfully.Check the status field. If completed, results are in the data field (for small results) or output_url field (for large results or ZDR).
404Not FoundJob with the specified ID not found.Verify the job ID is correct. The job may belong to a different API key.
500Internal Server ErrorServer error during job status retrieval.Retry. If the issue persists, contact support@landing.ai.

​
Job Status Values

The status field in the response indicates the current state of the job:
StatusDescription
pendingJob is queued and waiting to be processed.
processingJob is currently being processed.
completedJob completed successfully. Results are available in the response.
failedJob failed during processing. Check the failure_reason field for details.
cancelledJob was cancelled.

​
Understanding the Response

For completed jobs:
  • If results are less than 1MB, they appear in the data field as a ParseResponse object.
  • If results are 1MB or larger, the output_url field contains a presigned S3 URL (expires after 1 hour).
  • If Zero Data Retention is enabled, results are always saved to your output_save_url and not included in the response.
For failed jobs:
  • Check the failure_reason field for error details.
  • Common failure reasons include document processing errors or timeout.
Progress tracking:
  • The progress field shows completion as a decimal from 0 to 1 (e.g., 0.5 = 50% complete).
  • Progress is based on the number of pages processed.

​
