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 new-runtime-prior-coverage-checker-00dea18c -d '<json body>'
```

Example prompt: Before I write up this piece on agent payments, check New Runtime's prior coverage to see if the claim 'x402 enables machine-to-machine payments without OAuth' has already been reported — look back up to 90 days and topic it as 'agent payments'.

## When to prefer this

Choose this endpoint when you need to verify whether a specific URL, claim, or topic in the agentic software space has already been covered by New Runtime before publishing or referencing it. It is purpose-built for editorial deduplication and signal freshness checks in the agent-shaped software domain, rather than general web search or broad news retrieval.

## Known failure modes

- URL does not match expected https:// pattern — returns validation error
- Claim text shorter than 10 characters or longer than 300 — rejected with schema error
- Topic string outside 3-120 character range — rejected
- freshness_days outside 1-365 range — rejected
- No prior coverage found — returns matched:[] and verdict:'new'
- Service unavailable — HTTP 5xx with no coverage data returned

## 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 with a 'type' field (prior_coverage), a 'verdict' string (e.g. 'new' or 'duplicate'), a 'matched' array of previously matched articles or signals, and a 'clusters' array grouping related prior coverage by topic.
