## 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 stratalize-construction-cost-benchmark-76429f33
```

Example prompt: What are the hard cost per SF benchmarks, soft cost ratios, and escalation rates for a Class A multifamily concrete project in the northeast — I need this for a new construction underwriting?

## When to prefer this

Use this endpoint when a developer, lender, or underwriter needs authoritative, cryptographically verifiable construction cost benchmarks (hard cost per SF, soft costs, contingency, escalation) broken down by building type, region, and construction class, backed by NAHB, Turner CCI, and RSMeans sources. Prefer this over manual research or non-verified cost databases when auditability and source credibility are required.

## Known failure modes

- Invalid or missing region enum value returns 400 error
- Invalid building_type enum value returns 400 error
- Invalid construction_class enum value (not A, B, or C) returns 400 error
- Payment failure or insufficient USDC balance results in 402 Payment Required
- No data available for a specific combination of region and building type may return empty or partial results

## How this service works

Stratalize — attested finance, legal, healthcare, and compliance intelligence. Signed, independently verifiable receipt on every call (trust.stratalize.com/verify). Use when a developer or lender is underwriting a new construction project. Returns hard cost per SF by building type and region, soft cost ratios, contingency standards, and escalation rate. Source: NAHB + Turner CCI + RSMeans

## Output

Returns hard cost per square foot by building type and region, soft cost ratios, contingency standards, and escalation rate, all sourced from NAHB, Turner CCI, and RSMeans data. Each response is ML-DSA-65 cryptographically signed and includes a verifiable receipt link at trust.stratalize.com/verify.
