```sh
zero fetch --capability pharos-atlas-wastewater-plant-work-review-e2302e03
```

Example prompt: Pull the Pharos Atlas wastewater plant work review snapshot — I need the structured reference material on clarifier solids carryover and low aeration-basin dissolved oxygen, including the review workflow questions and subject descriptions.

## When to prefer this

Choose this endpoint when you need a structured, provenance-documented editorial reference specifically about wastewater plant operations — particularly clarifier solids carryover and aeration-basin dissolved oxygen — with defined scope, source dating, and usage rights. It is best suited for AI agents, researchers, or developers who need a citable, versioned knowledge snapshot rather than a live data feed or general web search. Prefer this over open-web search when auditability and defined limitations matter.

## Known failure modes

- Payment not completed — endpoint returns 402 requiring $0.01 USDC payment before content is delivered
- Invalid HTTP method — only GET, HEAD, DELETE are accepted; POST or PUT will fail
- Unexpected query parameters — schema forbids additional properties on queryParams, causing validation errors
- Resource unavailable — snapshot may be temporarily inaccessible returning 5xx
- Network or billing gateway timeout

## 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 pharos.trade-review.v1 schema, containing: review workflow steps, review questions scoped to clarifier solids carryover and dissolved oxygen topics, subject descriptions with definitions, site metadata, provenance details (source URL, release date, SHA256 checksums), and usage rights. The snapshot is dated and versioned for traceability.
