Secretary of State API: Instant Access to Primary Source Documents

Instant access to primary source documents via Secretary of State (SOS) APIs revolutionizes how businesses verify entities, assess risk, and ensure compliance. By directly interfacing with state databases, these APIs eliminate reliance on outdated or aggregated data, providing lenders and institutions with authoritative, real-time insights. Below, we break down the critical aspects of this capability.

What Constitutes a Primary Source?

In SOS API contexts, primary source records refer to data retrieved directly from official state Secretary of State websites in real time. This contrasts with cached databases, which store periodic snapshots of this information. For example, Cobalt Intelligence’s API dynamically fetches data like business registration status, filing history, and officer details directly from state portals, ensuring the most current records.

Live Data vs. Cached Data: Tradeoffs

Live Data

  • Accuracy: Reflects real-time updates (e.g., a business dissolved hours ago).

  • Latency: Retrieval times vary by state (e.g., Delaware takes 2–3 minutes).

  • Use Case: Critical for time-sensitive decisions like loan approvals or fraud checks.

Cached Data

  • Speed: Responds in seconds using pre-collected data updated monthly.

  • Limitations: May miss recent changes (e.g., new registrations or status updates).

Most APIs default to live data but allow users to prioritize cached results for speed. Cobalt’s API, for instance, offers configurable fallback to cached data if state websites are unresponsive.

Ensuring Data Freshness and Coverage

  • Live Data Currency: APIs like Cobalt’s interact directly with SOS websites, bypassing third-party aggregators. Screenshots with timestamps validate retrieval timing.

  • Cached Data Updates: Refreshed monthly, covering all 50 states and D.C. While comprehensive, cached databases may exclude businesses registered after the last update.

Latency Management

  • State Variability: Response times range from seconds (e.g., California) to minutes (e.g., Delaware) due to differences in state website infrastructure.

  • Mitigation Strategies:


    • Webhooks/Callbacks: Notify systems once live data is ready, avoiding polling delays.

    • Retry Logic: Automatically switches to cached data if live retrieval fails.

Data Accuracy and Reliability

  • Source Integrity: Direct integration with SOS websites ensures alignment with official records.

  • Verification Tools: Timestamped screenshots and source documents (e.g., articles of incorporation) serve as audit-proof evidence.

  • Downtime Handling: If a state website is offline, the API defaults to cached data or retries later.

State Coverage and Data Normalization

  • Full Coverage: All 50 states and D.C. are supported, though document availability varies (e.g., 18 states provide downloadable filings).

  • Normalization: Standardizes field names (e.g., “Active” vs. “Good Standing”) and formats across states, simplifying integration.

Cost and Integration

  • Pricing: Live data requests typically consume more credits (e.g., 3 credits for multi-state searches) due to higher operational costs.

  • System Integration:


    • APIs: RESTful endpoints with SDKs (Python, Java, Node.js) enable seamless CRM or underwriting platform integration.

    • Automation: Triggers live searches upon new lead creation in tools like Salesforce, with results posted via webhooks.

Use Cases and Data Points

  • Due Diligence/KYB: Verify active status, officer details, and UCC liens in real time.

  • Fraud Prevention: Flag inactive businesses or mismatched officer names using live screenshots.

  • Preferred Scenarios:


    • Live Data: Loan underwriting, audit trails, or high-risk transactions.

    • Cached Data: Batch processing or non-critical checks.

Retrievable Data:

  • Entity name, status, registration date.

  • Officer/director details (varies by state).

  • Historical filings, UCC liens, and court judgments (NY, Miami-Dade).

  • Screenshots of SOS search results with timestamps.

Error Handling

  • State Website Errors: API returns HTTP status codes (e.g., 503 for downtime) and automatically retries or uses cached data.

  • Missing Data: Distinguishes between “no records found” and technical failures, providing clear error messages.

The Bottom Line

For lenders, auditors, and compliance teams, SOS APIs with primary source access eliminate manual verification bottlenecks while ensuring regulatory adherence. By prioritizing live data’s accuracy and pairing it with cached backups for resilience, platforms like Cobalt Intelligence empower businesses to make faster, evidence-based decisions.

“Cobalt’s API lets us automate SOS checks that used to take hours. Now we process 5,000+ loan apps/month with confidence.”
