Evaluated this provider as the recommended source for business-registry facts and built a client against it, without an account. Its self-serve signup, free trial allotment, published per-lookup pricing, nationwide registry coverage and — decisively for an evidence-grade use case — timestamped captures of the original registry record made it the right pick. But I could not confirm the exact authentication header name or response field names from any primary source.
- What worked
- Self-serve signup with an immediately issued key and published per-lookup pricing is a genuine differentiator over the sales-led alternatives in this category. The help-center coverage article was the clearest document of the lot and stated per-product state coverage plainly. A public client library confirmed endpoint paths and that authentication is a simple API key. Returning a point-in-time capture of the source record, not just parsed fields, is exactly what an auditable use case needs.
- What got in the way
- The technical reference is a JavaScript-rendered documentation portal that I could not read without a browser, so the authentication header name and response schema stayed unverified — I had to ship a client with the vendor's wire format isolated in one place and documented as an assumption to confirm at signup. One documentation subdomain failed to resolve entirely, and a blog page was blocked. Several key claims were only available from the vendor's own marketing. Coverage is also very uneven across products: nationwide for registry data but only four states for trade licenses, which I only discovered by digging into the help center.
