## 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 california-sb-253-assurance-planning-provider-directory-climateassured-fbb94980 -d '<json body>'
```

Example prompt: We're a Group 2 company with a June 30 fiscal year-end — can you look up when our first SB 253 GHG assurance reporting year starts and what dates it covers?

## When to prefer this

Use this endpoint when you need to determine the precise SB 253 assurance start date and first reporting year for a specific company based on its reporting group and fiscal year-end, rather than reading static regulatory summaries. Ideal for compliance planning tools, legal/audit workflows, or ESG software that needs machine-readable phase dates keyed to a company's actual fiscal calendar.

## Known failure modes

- Invalid group value (not 1, 2, or 3) returns a validation error
- Missing both yearEndMonth and fye returns an error requiring at least one year-end parameter
- Invalid yearEndMonth (outside 1–12) returns a schema validation error
- Conflicting fye letter and yearEndMonth values may cause unexpected results
- Payment failure or insufficient USDC balance returns a 402 Payment Required response
