## 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-insulation-work-review-5a558d75
```

Example prompt: Pull the Pharos Atlas insulation work review snapshot so I can see how building insulation materials are identified and configured across wall, roof, and floor assemblies, along with the recommended installation workflow questions.

## When to prefer this

Choose this endpoint when you need a citable, structured editorial reference on building insulation trade topics — specifically material identification, assembly positioning, installation workflow, and safety considerations — with full provenance metadata. Prefer it over web scraping or general LLM knowledge when you need a versioned, auditable snapshot with checksums for research or compliance purposes.

## Known failure modes

- Payment not completed — endpoint returns 402 if x402 payment of $0.01 USDC is not supplied
- Invalid HTTP method — only GET, HEAD, DELETE are accepted; POST or PUT will be rejected
- Snapshot may reflect a fixed editorial release date (2026-10-19) and not current field conditions
- No live site inspection is performed — content is editorial and may not reflect real-time site status
- Network or billing gateway errors may return 5xx responses

## 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 structured JSON snapshot (schema: pharos.trade-review.v1) containing: the insulation work subject definitions keyed by topic, a list of review workflow steps, guiding questions for material identification and configuration, safety notes, a summary, items to avoid, and full provenance metadata including source URL, release date, and SHA-256 checksums for integrity verification.
