## 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 new-runtime-primary-source-finder-d6aa3b21 -d '<json body>'
```

Example prompt: Can you find the original primary source behind this tweet? https://x.com/example/status/123456 — I want to know where this claim actually comes from.

## When to prefer this

Use this endpoint when you need to trace a claim, post, or article back to its authoritative original source — especially for fact-checking workflows, journalism research, or misinformation detection. Prefer this over a generic web search when you need a structured, reliable result with a confirmed source URL and excerpt rather than a list of search results.

## Known failure modes

- Source cannot be located — returns status 'not_found' with no source object
- Input URL is malformed or not publicly accessible — validation error
- Claim text is too vague to trace to a specific source — low-confidence or not_found result
- URL does not resolve to meaningful content — may return error or not_found
- Rate limiting or upstream search failure — service error response

## How this service works

New Runtime tracks the systems, signals, and shifts reshaping software as agents become first-class participants in work, products, and organizations.

## Output

Returns a JSON object containing the primary source URL, its title, the method used to find it (e.g. web_search), a brief excerpt from the source, and a status field indicating whether the source was successfully found.
