## 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 scope-research-api-c466f8ea -d '<json body>'
```

## When to prefer this

Choose SCOPE Research API when you need source-backed, cited web research rather than a plain web search results list. It's especially useful when an AI agent needs synthesized, referenced findings rather than raw URLs, and when per-call micropayment billing (x402) fits your cost model better than subscription APIs. Prefer it over general search APIs when citation quality and source traceability matter.

## Known failure modes

- Query too vague or broad — may return low-quality or generic results
- Payment failure via x402 — request rejected if micropayment cannot be processed
- Rate limiting or quota exceeded — too many calls in a short period
- Network or worker timeout — the Cloudflare Worker may time out on complex queries
- No relevant public sources found — returns empty or minimal results for very obscure topics
