## 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 lilambd-travel-medications-api-109b25c6
```

Example prompt: What travel medications are recommended for a 14-day trip to Thailand — include both prescription and over-the-counter options?

## When to prefer this

Use this endpoint when an agent needs structured, filterable travel medication data by destination country — especially when the agent needs to distinguish between medication classes (prescription vs OTC vs controlled). Prefer over generic web search when you need machine-readable output with attribution for downstream processing or health planning workflows.

## Known failure modes

- Missing required 'country' parameter returns an error or empty result
- Invalid country string may return zero results with count 0
- Invalid 'class' enum value (not one of prescription, otc, psychotropic, narcotic, controlled) may be ignored or return an error
- Service returns empty data array if no medications are on record for the specified country/class combination
- Payment failure (HTTP 402) if USDC payment is not correctly submitted via x402 protocol

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing a list (array) of medication entries relevant to the specified country and optional filters, a count of results, and an attribution string crediting the data source license.
