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 pharos-atlas-cold-chain-work-review-62260a1b
```

Example prompt: Pull the Pharos Atlas cold chain work review so I can see the structured workflow steps and questions for matching products to their correct temperature requirements.

## When to prefer this

Choose this endpoint when you need a structured, versioned editorial reference on cold chain logistics work — specifically covering product-to-temperature-requirement identity and compliance workflows — with explicit provenance and sourcing. Prefer it over generic web search when you need a stable, citable snapshot with defined scope and limitations, particularly for AI agents that need reliable reference material without hallucination risk. Not suitable for real-time shipment tracking, live temperature monitoring, or regulatory compliance certification.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid HTTP method used (only GET/HEAD/DELETE accepted) — returns 405 Method Not Allowed
- Resource identifier not found — returns 404
- Network or upstream timeout — returns 503
- Unauthorized redistribution attempt is not enforced at the API level but violates licensing terms

## 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 snapshot (schema: pharos.trade-review.v1) containing: workflow steps for cold chain temperature compliance, key reference questions about product and temperature-requirement identity, subject definitions, a safety summary, provenance metadata (source URL, release date, SHA256 hashes), and licensing/rights restrictions. The snapshot is pinned to a specific release date (2026-10-19) and is intended for internal single-use reference only.
