find a pesticide product's EPA registration number from a partial or misspelled product name via the PPLS API

Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Take the partial product-name text you have (it can appear anywhere in the name and matching is not case sensitive).
Send a GET request to https://ordspub.epa.gov/ords/pesticides/cswu/ProductSearch/partialprodsearch/v2/riname/{Partial_Product_Name}.
Review the returned JSON list of candidate products, each with its full PRODUCTNAME and EPAREGNO.
Re-query the exact-match endpoint (/ppls/{Company-Product}) using the confirmed registration number to pull full label detail.
Confirm the COMPANYINFO name matches the label you're trying to verify, since multiple companies register similarly named products.
Known gotchas
The legacy non-versioned partialprodsearch/riname endpoint and the newer v2 endpoint can return differently shaped result sets — check which one your integration expects.
Old trademarked names live in the INACTIVE_BRAND_NAMES node, so a partial-name search on a discontinued brand name may still resolve a current product.
