## 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-rail-track-work-review-c1e06cb4

Example prompt: Pull up the Pharos Atlas rail track work editorial reference — I need the structured inspection guidance on rail-head wear and surface defects, including the review workflow and subject definitions.

## When to prefer this

Choose this endpoint when you need a structured, provenance-tagged editorial reference for rail track work topics — specifically rail-head wear, surface defects, and track fastener inspection — with clearly stated source dates, SHA256 integrity hashes, and usage rights. Prefer it over general web search when you need citable, scoped, machine-readable trade reference material with defined limitations rather than unstructured web content.

## Known failure modes

- Payment not completed — endpoint requires $0.01 USDC x402 payment before content is served
- Snapshot not found — if the resource identifier is invalid or retired
- Rate limiting or access restrictions on the billing endpoint
- Network errors reaching billing.pharosatlas.com
- Response may be a cached snapshot from a specific dated release (2026-10-19) and not reflect more recent track standards

## 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 object containing: the resource schema identifier (pharos.trade-review.v1), product name (railtrackwork-review), language, a snapshot ID, a primary review question about rail subjects, subject definitions (e.g. rail-head wear condition records), a workflow array of ordered steps, provenance metadata (source URL, release date, file SHA256, rights statement, kind of editorial release), and site context. The response is a static editorial snapshot from a specific dated release.
