How this service works
Look up medical terms in the NLM MeSH vocabulary - descriptor IDs, preferred label, entry-term synonyms, allowable qualifiers and related headings
Output
Returns a JSON object with the interpreted query, data source attribution, total count, a top_match object (descriptor ID, preferred label, entry terms, allowable qualifiers, see-also links), and an array of additional matching MeSH descriptors each with ID, label, and a link to the MeSH browser.
Example use cases
Standardize clinical term for research
“I need to standardize the term 'heart attack' using the NLM MeSH vocabulary — can you get me the official descriptor ID, preferred label, and any entry-term synonyms?”
Find allowable subheadings for indexing
“What subheadings or qualifiers am I allowed to use with the MeSH descriptor for 'diabetes mellitus'? I'm trying to index a medical article correctly.”
Resolve drug name to MeSH descriptor
“Look up 'aspirin' in the MeSH vocabulary and give me its descriptor ID, canonical label, synonyms, and any related headings — limit the results to 3.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/bio/mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative NLM MeSH-controlled vocabulary lookups for biomedical terms — ideal for indexing medical literature, standardizing clinical terminology, resolving synonyms to canonical descriptors, or finding allowable MeSH subheadings. Prefer this over general-purpose medical APIs when you specifically need MeSH descriptor IDs, qualifiers, and synonym entry terms from the official NLM vocabulary.
Side effects
- Term not found in MeSH vocabulary — returns empty descriptors array and null top_match fields
- Invalid or missing 'q' query parameter — returns error response
- Limit parameter outside 1-25 range — may return default of 8 results or validation error
- Very general or ambiguous terms may return unrelated descriptors
- Non-English medical terms may not match MeSH entries which are primarily English
