Steps
Request access via Kelly Registration Systems' API quote form (kelly-products.com/kelly-registration-systems/kelly-pesticide-product-registrations-api) — pricing is pay-as-you-go at $0.25 per query, with high-volume pricing available on request.
Confirm the target state is among the 39 states Kelly currently supports (e.g., includes CA, FL, TX, NY; does not cover all 50 states).
Submit a query keyed on the product's EPA registration number.
Parse the JSON response for State Abbreviation, State Specific Product Number, Registration Expiration Date, and State/Federal Restricted RUP Status.
Check the 'Date Since Last Uploaded Data' field per state, since data freshness depends on how recently that state submitted data to Kelly.
Known gotchas
Kelly is a private data aggregator, not the state agency itself — currency of the data depends entirely on each state's upload cadence to Kelly.
11 states are outside the documented 39-state coverage list; confirm coverage before assuming all-50-state support.
Pricing is metered per query on the pay-as-you-go tier, so unbounded or looped queries can get expensive quickly.
