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 scout-deep-21520fc8 -d '<json body>'
```

Example prompt: Do a deep research dive on whether Elon Musk's Neuralink has received FDA approval for human trials — I need exact quotes from public sources, any conflicting claims flagged, and source hashes for verification.

## When to prefer this

Choose Scout Deep over Scout Quick when you need thorough, high-confidence research with richer evidence, more source coverage, and conflict detection — particularly for fact-checking, investigative work, or producing verifiable receipts. Use when research quality and source breadth matter more than speed, and when you can supply specific seed URLs to focus the crawl. Scout Quick is better for fast, lightweight lookups.

## Known failure modes

- Invalid or empty goal string returns a validation error
- Supplied URLs exceed the 5-URL limit causing a 400 error
- Goal string exceeds 2000 character limit causing rejection
- Public sources are inaccessible or paywalled, resulting in incomplete evidence
- Payment authorization fails causing a 402 error before research begins
- Rate limiting or timeout from underlying web sources produces partial results

## How this service works

Deeper public web research with exact quotes, source hashes, conflicts, and a propose-only receipt.

## Output

Returns a structured JSON object containing a research brief with a title, an evidence array with exact quotes and source hashes, a conflict detection summary, a proposal object (status: proposed, applied: false indicating propose-only mode), the charge amount ($2 USD), and a receipt code (e.g. SC-XXXX) for auditing. The contract field identifies the service version as scout.paid-research.v1.
