How this service works
Purchase: DocQA - Document Extraction Verifier
Output
Returns a job_id, status string, and thread_id representing the newly created document extraction verification job on the402 platform, which can be polled for results using the job status endpoint.
Example use cases
Audit invoice data extraction accuracy
“I've got a batch of invoices that were processed by our AI extraction pipeline — can you kick off a DocQA verification job on them? I need to make sure the vendor names, amounts, and line items actually match what's in the original PDFs before we push anything to accounting.”
Validate OCR output before processing
“We just ran OCR on a stack of scanned medical forms and I'm nervous about errors slipping through. Can you start a document extraction verification job on the results so I can confirm the extracted fields are accurate before we load them into the patient database?”
QA check on parsed legal documents
“Before we sign off on this contract review, I need to verify that all the clauses and key terms our AI pulled from the source document are actually correct. Can you run a DocQA check on the extraction output and give me a job ID I can track?”
Technical details
Endpoint
POSThttps://api.the402.ai/v1/services/svc_a0260f914fb440ad/purchaseWhen to prefer
Use this endpoint when you need to programmatically verify or audit the accuracy of AI-extracted data against source documents, especially in pipelines where extraction errors are costly. Prefer this over generic document parsing services when you specifically need a verification/QA layer rather than raw extraction.
Side effects
- Payment failure if USDC balance is insufficient (payment error)
- Invalid or missing document/extraction payload returns 400 bad request
- Service unavailable or timeout returns 5xx error
- Job creation may succeed but extraction verification may fail asynchronously — check job status endpoint for final result
- Unsupported document format may result in failed job status
