}Built for production check extraction
Everything you need to parse remote-deposit and scanned check images at scale.
MICR routing + account number
Extract the MICR line: routing number, account number, and check number. Routing numbers are validated with the standard mod-10 checksum so bad reads are flagged programmatically.
Courtesy + legal amount reconciled
The numeric (courtesy) amount and the written (legal) amount are extracted independently and cross-checked. Mismatches surface a flag so you can route the check to manual review.
Payee, date, memo, and signature presence
Get the payee name, the issue date as ISO, the memo line, and a boolean indicating whether a signature is present in the signature region.
Async with webhooks
Upload returns a documentId immediately. Subscribe to a webhook or poll the job endpoint. Designed for batch ingestion and remote-deposit pipelines.
Bearer-token auth, deletable images
Personal Access Tokens scoped to your account. Check images encrypted at rest. Hard-delete via API or UI. Audit log per account.
Curl, Python, Node, anything HTTP
REST + JSON. Multipart upload. No SDK lock-in. Works from cron jobs, Lambdas, mobile backends, or your own service.
Who uses the check API
Remote deposit, lockbox, forensic accounting, AP, and audit teams use DocuClipper to turn check images into structured data.
Remote deposit capture
Embed check capture in your mobile or web app. Push the image to the API, get back MICR fields and amounts to validate before posting the deposit.
Forensic accounting + check matching
Bulk-process scanned checks and match each one to bank statement Check #N rows by amount and check number. Build a flow-of-funds view across accounts.
Lockbox + AP receipts
Lockbox vendors and AP teams scan paper checks for deposit. The API returns structured fields so the deposit, payee, and memo can be auto-posted to your AP or AR system.
Bookkeeping + petty cash workflows
Import paper-check receipts alongside bank statements and invoices using the same DocuClipper account. Push to QuickBooks, Xero, or NetSuite.
Fraud + dual-amount validation
The reconciled flag programmatically identifies checks where the courtesy and legal amounts disagree, often a strong signal for tampering or low-quality scans that need human review.
Audit + records retention
Long-term retention with searchable, structured metadata. Look up checks by payee, date range, or amount band without re-scanning images.

Start free trialCheck OCR API FAQ
DocuClipper has a 14-day free trial with full API access, including check extraction. No credit card required. After the trial, plans start at $39/month for 200 pages with API access on every paid plan.
MICR routing number (with mod-10 validation), account number, check number, payee, issue date, courtesy amount, legal amount, amount reconciliation flag, memo, and signature-presence boolean.
Yes. The API accepts JPEG, PNG, HEIC, TIFF, and PDF. Smartphone photos and remote-deposit-quality scans both work as long as the MICR line is in-frame and reasonably in-focus.
MICR fields extract at 99%+ on remote-deposit-quality images. The routing number is validated against the federal mod-10 checksum so bad reads are caught programmatically before they propagate downstream.
Checks have two amounts: the numeric ($1,250.00 in the courtesy box) and the written (One thousand two hundred fifty and 00/100). DocuClipper extracts both, compares them, and sets amountReconciled to true only when they agree. Mismatches usually mean a tampered check, a poor scan, or an OCR error worth human review.
Both. Upload returns a documentId immediately. You can poll the document endpoint until status is completed, or subscribe to a webhook that fires when extraction finishes. Most checks complete in under 10 seconds.
Bearer-token auth using a Personal Access Token (PAT) scoped to your account. Generate tokens in your account settings; rotate or revoke any time.
Yes. DocuClipper supports matching extracted check images against the Check #N rows on a bank statement so the bank-statement transaction inherits the payee and memo from the check image. See the bank statement page for the matching workflow.
The API auto-detects multiple checks on a single page and returns one structured check per detected document. Stubs and remittance advice are extracted separately.
Yes. The DocuClipper MCP server lets Claude Desktop, Cursor, and other agent runtimes call the check API directly via the convert_document tool.
