## 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-concrete-sealer-review-08e2aaa0
```

Example prompt: Pull up the Pharos Atlas concrete sealer reference — I need the diagnostic questions and workflow steps for figuring out how to approach a driveway concrete sealing job.

## When to prefer this

Choose this endpoint when you need structured, citable, trade-level reference material specifically about concrete sealing — including pre-job diagnostic workflows, surface-type context, and safety notes — rather than general web search results or unstructured DIY content. Particularly useful for AI agents that need to guide contractors or homeowners through concrete sealing decisions with defined scope and stated limitations.

## Known failure modes

- Payment not completed via x402 protocol — returns 402 Payment Required
- Invalid HTTP method used (only GET/HEAD/DELETE accepted)
- Snapshot may be dated if not refreshed; source_date indicates when editorial content was last updated
- No live site inspection data — provenance explicitly notes this is editorial reference only
- Redistribution or training use is prohibited per rights 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 structured JSON snapshot including: a list of diagnostic questions to ask before sealing (e.g. whether concrete is bare, previously sealed, stained, or coated), an ordered workflow array, subject-specific descriptions for surface types (driveway, patio, pool deck, garage floor), optional safety guidance, a summary, and full provenance metadata including source URL, release date, and file hashes. The snapshot is identified by a versioned snapshot ID (e.g. pharos-concreteseal-20261019-r1).
