List All Domains
Get the OMOP domain catalog. The result is wrapped under domains and the endpoint is not paginated server-side - the full ~20-row catalog comes back in a single call:
const { data, error } = await client.domains.list();
if (error) throw new Error(error.message);
for (const domain of data.domains) {
console.log(domain.domain_id);
}
Include concept counts and stats:
const { data } = await client.domains.list({ includeStats: true });
for (const domain of data?.domains ?? []) {
console.log(`${domain.domain_id}: ${domain.stats?.total_concepts ?? 'N/A'} concepts`);
}
Get Domain Concepts
Retrieve concepts within a specific domain. Wrapped under concepts; pagination on outer meta:
const { data, error, meta } = await client.domains.concepts('Condition', {
pageSize: 100,
});
if (error) throw new Error(error.message);
for (const concept of data.concepts) {
console.log(`${concept.concept_name} (${concept.concept_id})`);
}
console.log(`Page ${meta?.pagination?.page} of ${meta?.pagination?.total_pages}`);
console.log(`Total: ${meta?.pagination?.total_items} concepts`);
Filter by vocabulary:
await client.domains.concepts('Condition', {
vocabularyIds: ['SNOMED', 'ICD10CM'],
pageSize: 50,
});
Standard concepts only:
await client.domains.concepts('Drug', {
vocabularyIds: ['RxNorm'],
standardOnly: true,
pageSize: 100,
});
Include invalid / deprecated concepts:
await client.domains.concepts('Procedure', {
includeInvalid: true,
page: 1,
pageSize: 50,
});
Parameters
| Parameter | Type | Default | Description |
|---|
domainId (positional) | string | required | Domain identifier (e.g. 'Condition', 'Drug') |
vocabularyIds | string[] | - | Filter to specific vocabularies |
standardOnly | boolean | false | Only return standard concepts |
includeInvalid | boolean | false | Include deprecated concepts |
page | number | 1 | Page number |
pageSize | number | 50 | Results per page (max 1000) |
client.domains.list() returns the canonical OMOP domain catalog from GET /domains. The vocabulary-scoped version client.vocabularies.domains() queries GET /vocabularies/domains - different endpoint, different shape.
