## 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 pharos-atlas-drywall-work-structured-trade-review-e26f3b9c
```

Example prompt: Pull the Pharos Atlas structured trade review for drywall work — I need the wallboard and assembly identification guidance, workflow steps, and whatever safety and provenance notes come with it.

## When to prefer this

Choose this endpoint when you need a structured, provenance-backed editorial reference specifically about drywall work topics such as wallboard and assembly identification, and you require explicit scope, source context, and limitations. Prefer this over generic web search when you need a stable, versioned snapshot with SHA256-verifiable provenance for reproducible agent workflows or research pipelines.

## Known failure modes

- Payment not completed via x402 protocol — returns 402 Payment Required
- Invalid or missing HTTP method — request rejected
- Resource temporarily unavailable — upstream editorial data not accessible
- Network timeout — slow response from billing endpoint
- Snapshot not found — product identifier mismatch

## How this service works

Pharos Atlas provides structured editorial references for trade and blue-collar topics. Its paid x402 resources give researchers, developers, and AI agents defined reference material with stated scope, source context, and limitations. Each listing describes the specific resource being purchased.

## Output

A JSON object conforming to the pharos.trade-review.v1 schema, including: site metadata (domain, subjects, intents, contexts), a review object with workflow steps, guiding questions, safety notes, avoid items, and proof references, subject definitions (e.g. wallboard-and-assembly-identification), a snapshot identifier, source date, and detailed provenance (source URL, rights statement, SHA256 hashes of source file and projection).
