## 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 climateassured-sb-253-coverage-check-0dd186a1 -d '<json body>'
```

Example prompt: Can you check whether Acme Manufacturing is likely covered by California SB 253? They're a US-incorporated company, not based in California, with over $1 billion in annual revenue, California sales above the threshold, and no applicable exemptions like nonprofit or government status.

## When to prefer this

Use this endpoint when you need a fast, structured, rule-based assessment of California SB 253/SB 261 coverage for a specific company based on known facts about its incorporation, revenue, domicile, and sales. Prefer this over manual legal research when building compliance workflows, screening large numbers of portfolio companies, or automating regulatory triage. Use the free human checker at climateassured.com/am-i-covered/ for one-off manual checks; always verify conclusions with CARB for final compliance decisions.

## Known failure modes

- Missing required enum fields (ex, us, dom, rev, sales) result in validation errors
- Ambiguous inputs (e.g. 'u' for unsure on domicile) may yield an inconclusive verdict
- Regulatory changes not yet reflected in rule tree may produce outdated verdicts
- Payment failure (insufficient USDC) results in no response
- Result is informational only and may not reflect CARB's official determination

## How this service works

Neutral directory of GHG assurance providers and a planning guide for California SB 253 2027 assurance.

## Output

A JSON object with a verdict object indicating whether the company is likely covered by SB 253 and/or SB 261, a list of plain-English reasons explaining the determination, a coverage code, an unsure flag, and the input echo. Also includes a disclaimer, links to the free human checker and CARB verification page, and payment metadata.
