Compares two or more drugs side-by-side using FDA adverse event data, clinical trial data, and AI-powered analysis

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 medapi-compare-drugs-ebf91779 -d '<json body>'
```

Example prompt: Can you compare metformin and glipizide for me — I want to see their side-by-side safety profiles, adverse events, and an AI analysis of the key differences between the two?

## When to prefer this

Use this endpoint when you need a structured, AI-interpreted side-by-side comparison of two or more drugs rather than a single drug lookup. It combines FDA adverse event data, clinical trial data, and PubMed literature into one synthesized analysis — prefer this over single-drug endpoints when the user's question is inherently comparative (e.g. 'which drug is safer', 'what are the differences between X and Y').

## Known failure modes

- Invalid or unrecognized drug names return empty or partial drug data
- Fewer than two drugs provided may result in a meaningless comparison
- LLM analysis may time out or return null for ambiguous drug names
- API returns success: false if the drugs array is missing or malformed
- Rate limiting or payment failure via x402 on Base blockchain could block the request

## How this service works

Drug data, adverse events, clinical trials, PubMed. AI-powered medical analysis. 17 endpoints. x402 on Base.

## Output

Returns a JSON object containing individual drug data for each submitted drug, a structured comparison object summarizing key differences, and an LLM-generated comparative analysis covering safety, adverse events, and clinical relevance. The 'success' boolean confirms whether the request was processed correctly.
