## 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-tree-care-work-review-db48d28d
```

Example prompt: Pull up the Pharos Atlas tree care work reference snapshot so I can see the inspection workflow steps, key questions about tree condition and surrounding targets, and any safety notes included in the editorial release.

## When to prefer this

Use this endpoint when you need a provenance-backed, scoped editorial reference for tree care and arboriculture topics — specifically when you require defined workflow steps, standardized subject terminology, safety notes, and verifiable source metadata. Prefer this over general web search when reproducibility, stated limitations, and citable provenance are important for the use case.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Snapshot temporarily unavailable — returns 5xx server error
- Unsupported HTTP method used — returns 405 Method Not Allowed
- Resource identifier mismatch or endpoint moved — returns 404 Not Found

## 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 containing a structured editorial reference for tree care work, including: an array of workflow steps (e.g. recording tree observations and surrounding targets), an array of review questions (e.g. assessing tree condition), subject definitions with scope notes, safety guidance text, provenance metadata (source URL, release date, SHA256 hashes, rights statement), a snapshot identifier, source date, and site context including domain and intent clusters.
