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 suverse-health-covid-vaccine-country-timeline-5f12ad93 -d '<json body>'
```

Example prompt: Can you pull up the daily cumulative COVID-19 vaccine doses administered in Germany for the last 60 days so I can see how their vaccination rollout progressed?

## When to prefer this

Use this endpoint when you need a daily cumulative COVID-19 vaccination timeline for a single country without managing API keys. It wraps disease.sh/OWID data behind a simple pay-per-call x402 interface, ideal for agents that need public-health vaccination coverage data on demand without pre-registering for upstream API access.

## Known failure modes

- Unknown or misspelled country name returns an error or empty result
- Requesting more days than available historical data may return partial results
- OWID/disease.sh upstream unavailability may cause degraded or stale responses
- Payment failure (x402 protocol) blocks the request before data is fetched

## How this service works

COVID-19 vaccine doses administered for one country as a daily cumulative timeline (last N days). Keyless disease.sh / OWID. For agents tracking public-health vaccination coverage.

## Output

A daily cumulative timeline of COVID-19 vaccine doses administered for the requested country, covering the last N days. Each data point includes the date and the running total of doses given, sourced from disease.sh and Our World in Data (OWID).
