Checks whether a business activity qualifies as environmentally sustainable under the EU Taxonomy Regulation, including DNSH criteria, technical screening criteria, green asset ratio implications, and Article 8/9 fund classification impact.

## 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 esgpulse-eu-taxonomy-alignment-checker-23f2e544
```

Example prompt: Can you check whether our commercial real estate construction activity qualifies as sustainable under the EU Taxonomy — specifically whether it passes the DNSH criteria and technical screening, and what that means for our Article 9 fund's green asset ratio?

## When to prefer this

Use this endpoint when you need to determine whether a specific economic activity qualifies as environmentally sustainable under the EU Taxonomy Regulation, particularly for green asset ratio calculations, SFDR Article 8/9 fund disclosures, or green bond eligibility. Prefer this over general ESG scoring endpoints when the question is specifically about EU regulatory taxonomy alignment rather than broader ESG ratings or CSRD disclosure requirements.

## Known failure modes

- Activity described too vaguely to map to a NACE code — returns ambiguous or no match
- Activity falls outside EU Taxonomy covered sectors — returns not eligible with explanation
- Insufficient detail to assess DNSH criteria — partial results returned
- Payment not received — 402 Payment Required response
- API unavailable on Vercel — 500 or timeout error

## How this service works

ESGPulse delivers real-time ESG intelligence: CSRD compliance roadmaps, EU Taxonomy alignment checks, supply chain due diligence, emissions analysis, greenwashing risk, and more. x402 micropayment API.

## Output

Returns an assessment of whether the specified business activity qualifies as EU Taxonomy-aligned, detailing which environmental objectives it may contribute to, the applicable DNSH (Do No Significant Harm) criteria, technical screening thresholds, and the implications for green asset ratio reporting and Article 8/9 fund classification under SFDR.
