# SiteCheck Trade & Energy – American Carbon Registry (ACR) Projects

> SiteCheck Trade & Energy – American Carbon Registry (ACR) Projects is a paid API for AI agents from api.tradeenergy-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Search and retrieve American Carbon Registry project records from ICE GreenTrace, including project type, status, methodology, developer, credits issued, and registry links.

## Facts

- Endpoint: GET https://api.tradeenergy-api.workers.dev/api/energy/american-carbon-registry?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-29
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/sitecheck-trade-energy-american-carbon-registry-acr-projects-9a40143b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_1OxU48ADjr2-xBPJ9xxZn

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sitecheck-trade-energy-american-carbon-registry-acr-projects-9a40143b
```

Example prompt: Search the American Carbon Registry on ICE GreenTrace for active forest carbon projects — show me the first 10 results including each project's ACR ID, developer, methodology, and how many credits have been issued.

## When to prefer this

Use this endpoint when you need structured, searchable data from the American Carbon Registry specifically — including project pipeline status, methodology details, and credit issuance history from ICE GreenTrace. Prefer it over general web search when you need machine-readable ACR project metadata for compliance research, carbon market analysis, or due diligence workflows.

## Known failure modes

- Invalid project type code returns no results or an error
- Page number out of range returns empty results array
- Search query with no matches returns total: 0 and empty results
- Rate limiting or payment failure returns 402 or 429 status
- ICE GreenTrace upstream unavailability causes timeout or 503

## How this service works

American Carbon Registry (ACR) projects from its public registry on ICE GreenTrace: search by text or project type (forest carbon, landfill gas, refrigerants, orphaned wells, CCS …); per project the ACR ID, name, status, type, methodology, developer, crediting program, country, credits issued, last status change and registry links, plus the total number of matching projects.

## Output

Returns a JSON object with the search query, page number, project type filter, total count of matching projects, the ICE GreenTrace source URL, a checkedAt timestamp, and an array of project records — each containing: internal key, GreenTrace URL, project name, ACR ID, status, type, country, crediting program, developer name, developer URL, methodology, public stage, credits issued, and last status change timestamp.
