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 stealthguard-deep-web-dossier-de71bb23 -d '<json body>'
```

Example prompt: Put together a deep intelligence dossier on Anthropic's recent model releases — pull from multiple web sources and make sure the report is scrubbed clean of any prompt injection attempts before you give it to me.

## When to prefer this

Choose this endpoint when you need a multi-source web intelligence synthesis that is explicitly hardened against prompt injection — especially when the research output will be fed directly into an AI agent context window. Prefer it over raw web scrapers or general search APIs when agent safety and structured markdown output are priorities, particularly for OSINT, due diligence, or crypto/protocol research tasks.

## Known failure modes

- Empty or vague body payload returns incomplete or generic dossier
- Target topic has insufficient indexable web presence, yielding sparse results
- CanaryGuard may over-sanitize legitimate content that resembles injection patterns
- Slow response times on render.com free-tier cold starts
- Malformed input schema (missing required type, method, or bodyType fields) returns 400 error
- Rate limiting or payment failure on x402 protocol returns 402 or 429

## How this service works

Multi-source stealth web synthesis + CanaryGuard injection firewall + structured markdown intelligence dossier.

## Output

A structured markdown intelligence dossier synthesized from multiple web sources, with all content pre-screened and sanitized by the CanaryGuard injection firewall. The response includes a status field, tool identifier, and agent_continuation object, along with the cleaned markdown report safe for direct ingestion into AI agent context windows.
