## 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 climate-action-reserve-carbon-offset-project-registry-066cfb41
```

Example prompt: Show me all registered forest carbon projects in California from the Climate Action Reserve registry, sorted by credits — I want to see the project names, owners, verifiers, and how many offset credits each one has registered.

## When to prefer this

Use this endpoint when you need structured data about carbon offset projects registered specifically with the Climate Action Reserve (CAR) — including ARB and Washington ECO compliance status, verifier identity, and credit volumes — especially for North American voluntary and California compliance market research. Prefer this over general web searches when you need machine-readable, filterable registry data rather than narrative summaries.

## Known failure modes

- Invalid or unsupported filter values may return empty result sets
- Limit out of range (not 1–200) may return an error or be clamped
- Upstream APX report unavailable may cause service errors or stale data
- Very broad queries with no filters may hit default limit of 50 results requiring pagination
- Country codes or state names must match exact registry formats or filtering will not work

## How this service works

Carbon offset projects registered with the Climate Action Reserve (CAR, the North American voluntary and California compliance registry) from its public APX project report: project ID, name, developer/owner, verifier, project type, status, compliance (ARB/WA ECO) status, location, offset credits registered, listed and registered dates, SDG tags. Filter by type, status, state, country or text; sorted by credits.

## Output

A JSON object containing the total number of matching projects, the current offset for pagination, the source URL (APX report), a checkedAt timestamp, and an array of project objects each with: projectId, name, type, status, owner, operator, developer, verifier, location, state, country, website, listed date, registered date, complianceId, complianceStatus, creditsRegistered, and SDG tags.
