Certificates Of Documentation API

Certificates of Documentation OCR & Data Extraction

A US Coast Guard Certificate of Documentation establishes a vessel's nationality, ownership, and admissibility to trade. Renewals, lien searches, and compliance checks still mean rekeying the vessel name, official number, hailing port, and owner from each certificate. ByteIt reads digital and scanned certificates into structured JSON. Examples include certificate number, vessel name, hull identification, owner name and address, tonnage, and many more. Operators use the sample record to renew documentation or check a vessel before it is chartered or financed.

Eliminate manual keying errors across owner names, hull numbers, and tonnage figures

Accelerate registration and renewal workflows with turnaround measured in seconds, not days

Scale document processing without adding headcount during peak boating seasons

How it works

  1. Step 1

    Upload

    Send the document to the API as a file or a URL no special formatting required.

  2. Step 2

    The engine reads the document

    The engine analyzes the page layout and identifies the content that matters. ByteIt's extraction engine reads the layout of USCG Certificate of Documentation forms, detecting labelled fields such as certificate number, official number, vessel name, hailing port, HIN, owner details, tonnage, dimensions, propulsion type, endorsements, and issuing authority from both digital PDFs and scanned images.

  3. Step 3

    Structured JSON is returned

    Every extracted element comes back as structured JSON, positioned and typed, ready to feed into downstream systems.

  4. Step 4

    Confidence-based review

    Each field carries a confidence score, so low-confidence results can be routed for human review instead of trusted blindly.

Features

Reads both digital PDFs and scanned images of USCG-issued Certificates of Documentation

Extracts certificate number, official number, vessel name, hailing port, hull identification number (HIN), owner name and address, managing owner, and endorsements

Captures technical vessel data including gross tonnage, net tonnage, length, breadth, depth, and propulsion type

Outputs structured JSON with per-field extraction for direct integration into vessel management or compliance systems

Use cases

Marine Vessel Registration & Renewal

A marina operator or vessel registry receives hundreds of COD renewals each month. Instead of clerks manually typing vessel and owner data into a registration database, ByteIt extracts the certificate number, expiration date, owner name, and vessel details in seconds. The structured output can be forwarded directly into a registry management system, reducing processing time per certificate from minutes to a few seconds.

Lien & Title Search Automation

Financial institutions and marine insurers need to verify vessel ownership and outstanding liens before underwriting or financing. ByteIt extracts owner name, official number, HIN, and endorsements from each COD, enabling automated cross-checks against title databases without manual document review.

Compliance & Coast Guard Audit Preparation

Fleet operators and commercial vessel owners must maintain current certificates for every vessel in service. ByteIt extracts issue and expiration dates, vessel type, and endorsements from CODs across the fleet, feeding a compliance dashboard that flags upcoming renewals and expired documents before they become audit findings.

Vessel Inventory & Asset Management

Companies managing multiple vessels for charter, transport, or logistics need a centralised inventory of vessel specifications. ByteIt extracts technical fields such as gross tonnage, length, breadth, depth, propulsion type, and many more from each COD, populating an asset register that can be queried by capacity, size, or vessel type.

Downstream System Integration

Extracted COD data can be connected to your marina management software, fleet ERP, or compliance tracking platform using workflow automation tools like n8n, Zapier, or Make, eliminating manual data re-entry between systems.

How do I integrate ByteIt into my vessel management system?

ByteIt provides a REST API that returns structured JSON. You can connect the output to your registry, ERP, or compliance platform either via direct API calls or through no-code workflow tools such as n8n, Zapier, and Make.

Does the API support multi-page Certificates of Documentation?

Yes. ByteIt processes multi-page documents and extracts fields from all pages, consolidating the results into a single structured JSON output.

How is ByteIt priced?

ByteIt offers a usage-based pricing model with no upfront commitment. You pay per document processed. Check the pricing page on byteit.ai for current rates and credit pack options.
