Choosing Your Verification Partner: Cobalt vs Middesk vs Trulioo

Executive Summary: Business verification isn't one-size-fits-all. Different lenders have different requirements: some need deep U.S. Secretary of State data, others need global coverage, some want a full identity platform, and some need to confirm that the people behind the business are who they say they are. Understanding how Cobalt, Middesk, Trulioo and iDenfy differ helps you choose the right checks for your underwriting needs.

This best business verification API comparison breaks down the key differences so you can make an informed decision based on your actual requirements, not marketing claims.

Cobalt Intelligence: Direct-to-Source SOS Specialist

Cobalt focuses specifically on Secretary of State verification with a direct-to-source approach.

Core strengths

Live SOS lookups: Cobalt can query state websites directly in live mode. It also has a separate cached mode. Check the mode and source timestamp before interpreting a result as current state evidence.^[1]

Timestamped screenshots: A completed live SOS lookup can include a timestamped screenshot when requested in a supported state. Keep the source URL and retrieval time with the result. Cached results and interim cached matches do not include a new live screenshot.^[1]

Flexible response modes: Cached mode uses stored results. Live mode queries the state and can remain pending while the lookup continues. An available cached match may accompany a pending live response; its updatedAt indicates its age, and it has no new live screenshot. Use retryId or the configured callback to retrieve the eventual live result.^[1]

UCC lien data: UCC data can be requested with a supported SOS search. Confirm the current state, debtor-name and filing coverage before using a result for lien review.^[1]

Limitations

Geographic scope: Verify current coverage for each requested state and product. Workflow scope: An SOS result is entity evidence; identity checks, credit decisions and a complete ownership review require the appropriate additional controls. State variation: Publicly available fields differ by state.

Best fit

Lenders who need state-record entity evidence, optional screenshots on completed live requests, and a workflow that keeps cached, pending and completed live results distinct.^[1]

Middesk: The Business Identity Platform

Middesk groups business identity and risk checks in one platform. Confirm which products are included in your proposed workflow.^[2]^[4]

Core strengths

Business verification: Middesk documents business-name and address checks, TIN verification, sanctions screening and configured KYC checks for people associated with a business. Its documentation also includes international business verification.^[2]

Credit assessment: Middesk documents UCC and tax-lien search, UCC filing and termination, and legal-record research.^[4]

Address risk insights: Middesk classifies address characteristics such as virtual or mailbox locations, deliverability and registered-agent use, and flags how often an address appears across business registrations.^[5]

Web analysis: Middesk documents analysis of website content, domain ownership and other web-presence indicators, with checks for consistency between submitted information and online sources.^[6]

Limitations

Evaluation points: Confirm which products, sources and refresh signals are included in the proposed workflow. Ask for sample exports, screenshot availability, exception handling and a quote for your actual volume. A wider product set needs a clearly defined scope.

Best fit

Organizations that need business and associated-person checks in a configured workflow, with optional credit-risk, lien and web-presence products. Confirm the included products and review steps.^[2]^[4]

Trulioo: Global Identity Platform

Trulioo documents person, identity-document and business-verification services through its platform API. Services can be called individually or combined for a configured workflow.^[7]

Core strengths

Country coverage: Trulioo's current Business Verification guide describes entity checks in 195+ countries. Coverage and source groups vary by country and jurisdiction; verify the markets relevant to your borrowers.^[3]

Combined KYC/KYB: Trulioo's platform offers person, identity-document and business-verification services, which can be called individually or combined for a selected workflow.^[7]

Source selection: Trulioo documents public records, government registries, credit agencies and international watchlist groups. The actual sources depend on the country and account configuration.^[3]

Market-specific integration: Supply the correct country and jurisdiction of incorporation. Ask the provider to confirm required registration identifiers and supported document and language combinations for those markets.^[3]

Watchlist screening: International watchlist sources are documented within the business-verification workflow, subject to country and source availability.^[3]

Limitations

Evaluation points: Check source availability, required identifiers and jurisdiction-specific fields for your target markets. Request example outputs and test your exception cases before choosing the configured workflow.^[3]

Best fit

Organizations that need business verification across multiple countries and jurisdictions, with account-configured sources and the appropriate person or document checks.^[3]^[7]

iDenfy: Owner and Guarantor Verification for KYB

iDenfy verifies the people behind a business and provides tailored KYB onboarding questionnaires for collecting company information. Its published feature list covers identity verification, AML screening and business verification.^[8]

Core strengths

Custom questionnaires: Teams can request company information and documents, then configure identity and AML checks for the people associated with the business.^[8]

U.S.-specific checks: iDenfy offers an optional U.S. criminal-background check; its documented automatic check applies to U.S.-issued documents.^[9] Its AAMVA driver-license database check runs only for approved identity verifications using a U.S. driver's license. It supports 42 states. Alaska, California, Delaware, Louisiana, Minnesota, New York, Pennsylvania and Utah are excluded, as are Washington, D.C., Puerto Rico and other U.S. territories. Database matching does not by itself authenticate the physical document or establish that its presenter is the legitimate holder; iDenfy recommends document-authenticity and biometric checks alongside it.^[10]

Company information checks: AI data comparison cross-checks company information for discrepancies. Ownership questionnaires, identity checks and AML screening support review of the people associated with the company.^[8]

UBO and AML coverage: The platform supports identity verification and sanctions/PEP screening, with monitoring options for company beneficiaries.^[8]

Pricing option: Approved-only identity-verification billing is available. Confirm which services and outcomes your agreement covers.^[8]

Limitations

SOS report workflow: Reports are ordered on demand and initially have an IN_PROGRESS status. The cited SOS documentation does not specify timestamped state-website screenshots. If your underwriting process requires that visual evidence, confirm the report outputs or add a completed live SOS lookup with screenshots.^[11]

UCC scope: For lien due diligence, confirm whether the selected service supplies registry search results or documents collected from an applicant. A completed questionnaire alone does not establish that a registry lien search was performed.

Applicant participation: An ID-and-selfie flow requires the owner or guarantor to participate. Plan an exception route for an incomplete identity check.

Best fit

Organizations that need identity verification for owners and personal guarantors, KYC/KYB and AML checks in a configured onboarding flow, or custom questionnaires to collect company information.^[8]

Decision Framework: Which Is Right for You?

Choose Cobalt if:

Your workflow requires a completed live state lookup, optional requested screenshots, and a clear distinction between cached screening and completed live evidence. Confirm state-specific fields and UCC coverage for the intended use.^[1]

Choose Middesk if:

You want configured business, TIN, sanctions or associated-person checks, and need to evaluate optional lien, credit-risk or web-presence products within that workflow.^[2]

Choose Trulioo if:

You need country-specific business verification and a configured combination of business, person or document services. Confirm the source groups and identifiers needed in each jurisdiction.^[3]

Choose iDenfy if:

Your loans require personal guarantees and you need identity evidence for the applicant; you want document and liveness checks for owners; you need AML screening of beneficial owners; or your applicant-identification flow includes supported non-U.S. documents.

The Hybrid Approach

Evaluate entity evidence, applicant identity and lien searches as separate requirements. The following are example workflow designs, not claims that the providers have a formal integration:

Example funding sequence: For a U.S. business-loan application, review the entity record and the applicant's identity as separate evidence. If the business record matches but the applicant cannot complete the required owner check, route that exception for review. An active entity record does not resolve the applicant question. For a secured loan, obtain the appropriate legal-name lien search as a separate step; an ID check or questionnaire is not a substitute for that search. Set the required review gate in your own funding policy. Include an unsupported AAMVA jurisdiction, such as California, in your pilot. Decide how an owner will complete the alternative identity flow; an unavailable database check is not a successful match.^[1]^[4]

Common combinations:

• Cobalt + iDenfy (or another KYC provider): Use Cobalt for completed live SOS verification with requested screenshots, and iDenfy to check the owners and guarantors behind the entity with ID, biometric and AML checks. Choose and validate the workflow for your own requirements.

• Middesk + a defined lien-search workflow: Check whether the documented UCC search meets your debtor-name and state-coverage requirements before adding another provider.^[4]

• Trulioo + a U.S. SOS source: Use the configured international workflow for relevant markets and a completed Cobalt live SOS lookup where your U.S. process calls for state-source entity evidence.^[3]^[1]

The right combination depends on your borrower profile, geographic focus, and compliance requirements.

Key Questions to Ask

When evaluating any verification provider, get specific answers to these questions:

Data sourcing

• Where does your business data come from?

• How often is it updated?

• Do you query state sources directly or use aggregated databases?

• What's your coverage for [your specific states/countries]?

Verification proof

• Can you provide screenshots or visual evidence of verification?

• What audit documentation is included with each verification?

• How long are verification records retained?

Pricing

• What's the per-verification cost?

• Are there volume tiers or minimum commitments?

• Which features are included vs. add-on pricing?

• What's the total cost for my expected volume?

Integration

• What's the API integration timeline?

• Do you offer sandbox/testing environments?

• What support is available during integration?

• What's your uptime SLA?

Specific capabilities

• What UCC lien coverage do you offer?

• Can you provide officer/beneficial owner data?

• What's your response time for [my priority states]?

• How do you handle entities not found in state databases?

Making the Decision

The "best" verification provider depends entirely on your requirements:

If live SOS data and visual proof matter most: Confirm that your selected workflow returns completed live results and the requested timestamped screenshots. Keep cached and pending results visibly distinct in your underwriting record.

If you want several checks in one platform: Evaluate Middesk's business-verification, credit-risk and lien products against the scope your team actually needs.^[2]^[4]

If you operate across countries: Evaluate Trulioo's configured sources and identifiers for the actual countries and jurisdictions in your borrower base.^[3]

If your risk sits with the people behind the business: iDenfy's identity and biometric checks can help verify who is applying. Combine the appropriate owner checks with a completed Cobalt live SOS lookup when you also need current entity evidence.

Choose the combination that supplies the evidence your underwriting process requires. Define who reviews a mismatch, how a pending result is handled, and what evidence permits the next step before rollout.

Questions for Your Verification Pilot

What if an owner name differs from records?

Route the mismatch for review. Record the legal entity, the applicant identity and the claimed role separately; request evidence connecting them before deciding. A completed identity check alone does not establish authority to act for the company.

How should teams handle a pending SOS report?

Keep the report pending until the selected evidence is available. Define who reviews unresolved cases and what permits the next underwriting step. A cached match may help review, but it should retain its own timestamp and evidence label.

What belongs in a combined verification audit trail?

Keep the entity identifier, source and retrieval time, applicant identity-check reference, relationship evidence and reviewer decision together. Record which vendor supplied each result so a later reviewer can reconstruct the decision.

How can teams test applicant handoff friction?

Run a controlled pilot with completed, abandoned and exception cases. Compare where applicants stop and how reviewers recover the case. Separate identity-flow completion from the business-record match so one result does not hide another bottleneck.

How should lenders compare verification providers in a pilot?

Give each provider the same permitted test cases and written acceptance criteria. Include ambiguous names, missing records, pending results and applicant exceptions. Compare the usable evidence and recovery path before expanding the workflow.
