## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability disease-ontology-lookup-mondo-mydisease-80b24827 -d '<json body>'
```

Example prompt: Look up 'amyotrophic lateral sclerosis' in the MONDO disease ontology and give me its canonical label, official definition, and all known synonyms.

## When to prefer this

Use this endpoint when you need to standardize, validate, or enrich a disease name against the MONDO biomedical ontology — ideal for clinical NLP pipelines, EHR normalization, bioinformatics workflows, or any task requiring authoritative disease terminology with definitions and synonyms.

## Known failure modes

- Disease name not found in ontology — returns empty or null results
- Ambiguous query matches multiple diseases — may return top hit or list
- Malformed query string — HTTP 400 or empty response
- Ontology data not available for rare/novel diseases
