API Integration Basics

Which fields are required for a Secretary of State lookup?

Can I integrate Cobalt’s API into my web application or platform?

How should we handle long-running SOS searches? What does “Incomplete” mean?

Can I search all 50 states at once?

Can we control which fields are returned in Cobalt’s API response?

Can we simplify reports for clients so they don’t see unnecessary details?

Can we change the names of fields returned by the API?

Can I search by a principal or owner’s name instead of the business name?

Can we use Cobalt to return Secretary of State screenshots instead of having staff capture them manually?

Can I specify the type of entity for an OFAC check (person vs. business)?

Testing & Trialing the API

How can I test the API before choosing a plan?

Do you provide a sandbox or test environment for API integration?

How long is the free trial API key valid? Can it be extended?

How many test calls are included in the trial?

Any guidance for large batch runs?

Any practical steps to boost NY batch hit rates?

How should we validate batch results when inputs are messy?

For batch work, should we track the “actual name searched” separately from the raw client input?

Matching & Confidence

How does Cobalt determine which record is the best match?

What’s a practical NY “waterfall” we can implement on our side?

What “waterfall” name-matching strategy works well for tight state searches (e.g., NY)?

How should we handle generic names?

If we have an entity suffix (e.g., “LLC”), should we include it in the query?

How does string length affect confidence scores?

Why did I see confidenceLevel = 1.0 when the names didn’t match?

How does the API handle messy or inconsistent entity names?

Do you treat “&” the same as “and”?

Why did shortening the name to a core form help?

How should we combine confidenceLevel with address signals?

We got a low-confidence result that shared the ZIP but not the name—why?

Fields (name/score/URL)? Can we get more?

Can we see more than just the top match when several are close? How should we use the alternatives list?

Will Cobalt’s API detect entity name changes (e.g., Pizza Inc → Pizza LLC)?

How does the API handle name disambiguation (e.g., punctuation, suffix differences)?

Do you provide DBA (fictitious name) information?

Can Cobalt return multiple possible matches with confidence scores?

Address & ZIP Handling

Why didn’t some results include address fields we expected?

We have extra context that you don’t—can we apply it to batch disambiguation?

Can we rely on address fields to help when names are imperfect?

Why doesn’t possibleAlternatives always include addresses?

If I include a ZIP code but it doesn’t match, what happens?

Does the system fall back to ignoring the ZIP code if no match is found?

New York feels stricter—plural vs. singular differences killed some results. Why?

Our client names often include location text. Should we clean that before searching?

Can we pass city/ZIP/street or “search by address” to improve matches? Will the API adjust its waterfall?

Why are responses slower when filtering by ZIP?
