Resolve a batch of codes

Bearer token with your API key. Keep the key server-side.

Makes a retry count once. 8 to 128 letters, digits and . _ : / + -, starting with a letter or digit. For 24 hours the key is bound to your workspace and the exact request; reusing it for different work is refused with 409.

1 to 100 codes, each any code CODE-LOOKUP accepts. Results keep their order and duplicates. An empty list, an empty string or an item over 512 characters is 400; more than 100 is 413. Any other code gets its own row.

The code exactly as you sent it, untrimmed.

What the code is: ndc, barcode, rxcui, unii, set_id or application.

What the code names, as CODE-LOOKUP reports it, plus ambiguous, not_found, unrecognized, unavailable, historical (a retired RxCUI with no single successor), unresolved (an RxCUI or UNII with no drug) and unsupported (an RxCUI that is not a drug) in place of an error. A package NDC that several products carry is products.

Why a row is unavailable: package_matches_exceed_limit (a package NDC in more than 1000 catalog rows), product_labels_exceed_limit (a product NDC on more than 64 labels) or product_list_exceeds_limit (the batch’s product lists passed 5,000 catalog rows; send that code alone). Only that row is affected.

The product summary when the code names one product.

The package NDC when the code names a package.

The drug’s RxCUI and preferred name when the code names a drug. A redirected row always has it: the successor.

For an NDC DailyMed no longer lists but RxNorm does: the RxCUI it names.

For an NDC neither DailyMed nor RxNorm lists: the ingredient it belongs to, not a product.

The product NDCs when the code names several products, or the products an ambiguous code could be, in ascending order, at most 25.

True when more products than those listed may carry the code.

The RxCUIs to choose from when the code is ambiguous or retired with no single successor, including a code whose layouts reach different RxNorm concepts or clinical profiles. A redirected row lists its one successor. An ambiguous row always has this or product_ndcs, never both.
