## 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 klymax402-event-resolver-api-83caff43
```

Example prompt: Did Bitcoin reach $100K by April 2026? Resolve this as a binary yes/no question and tell me how confident you are, along with the sources you used.

## When to prefer this

Use this endpoint when you need to resolve a specific real-world event question with evidence and a confidence score, especially for prediction market settlement, fact-checking, or verifying whether a milestone was reached. Prefer this over general web search when you need a structured, scored resolution with cited sources rather than raw search results.

## Known failure modes

- Question is ambiguous or too vague to resolve — low confidence score returned
- Event has not yet occurred — resolution may return null or inconclusive
- No reliable web sources found — empty sources and evidence arrays
- Malformed or missing question parameter — API returns an error
- Numeric resolution type used for a binary question — may return unexpected format

## How this service works

## Output

A JSON object containing the resolved answer (resolution), a confidence score between 0 and 1, the original question, a timestamp, a list of evidence snippets, and the source URLs consulted to reach the resolution.
