## 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 locus-before-you-sign-address-due-diligence-bundle-b800689a -d '<json body>'
```

Example prompt: I'm about to sign a lease on a apartment at 412 Elm Street, Austin TX 78701 — can you run a homebuyer due diligence check on it covering the last 24 months and flag any local changes, ordinances, or property issues I should know about before I commit?

## When to prefer this

Use this endpoint when you need a single convenience call that bundles parcel, local-change, and ordinance analysis together for one US street address, especially in pre-signing real estate scenarios (renting, buying, or siting a business). Prefer this over calling individual locus.report sub-endpoints when you want a holistic, citation-backed snapshot without orchestrating multiple API calls yourself. Choose a specialized sibling endpoint instead if you only need one specific data type (e.g., only environmental data or only ordinance analysis).

## Known failure modes

- Address not found or unresolvable — component status will reflect low readiness with no parcel data returned
- Address is outside supported US coverage area — returns coverage caveat with partial or empty results
- Component readiness too low to trigger paid analyses — only free parcel checks run, paid modules skipped
- Invalid intent enum value — request rejected with validation error
- lookbackMonths out of allowed range (1–60) — request rejected
- Payment failure via x402 protocol — call does not complete

## How this service works

Convenience due-diligence bundle for one street address. Runs free coverage-aware parcel checks plus paid local-change and property bill/ordinance analysis when component readiness is strong. Returns componentStatus, citations, caveats, and verify-next steps. Not inspection, appraisal, valuation, screening, or legal advice. Install agent skill: npx @velinussage/locus-agent-skill add.

## Output

Returns a structured JSON response with componentStatus (indicating which sub-analyses ran and their readiness), cited local-change signals, property bill and ordinance findings, parcel metadata, caveats about data coverage, and suggested verify-next steps for the user to pursue. Does not constitute an inspection, appraisal, valuation, tenant screening, or legal advice.
