# EU Taxonomy Alignment Check (ESG Pulse)

> EU Taxonomy Alignment Check (ESG Pulse) is a paid API for AI agents from esgpulse.theaslangroupllc.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-16).

Checks whether a business activity qualifies as EU Taxonomy-aligned sustainable finance, returning DNSH criteria, technical screening results, green asset ratio, and Article 8/9 fund implications.

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 eu-taxonomy-alignment-check-esg-pulse-3da6320f
```

Example prompt: Can you check whether a solar energy generation activity qualifies as EU Taxonomy-aligned sustainable finance — specifically whether it meets the DNSH criteria, passes the technical screening, and what that means for Article 9 fund classification?

## When to prefer this

Use this endpoint when an agent needs to determine EU Taxonomy alignment specifically — including DNSH criteria, technical screening thresholds, and SFDR Article 8/9 fund implications — rather than general ESG scoring or carbon footprint analysis. Ideal for sustainable finance compliance workflows, green bond due diligence, and regulatory reporting under SFDR or EU Taxonomy regulations.

## Known failure modes

- Unrecognized or ambiguous economic activity returns an error or low-confidence result
- Activity description too vague for technical screening — may require a NACE code
- Activity falls outside EU Taxonomy-covered environmental objectives — returns not eligible
- Missing required activity or sector parameters — returns 400 or validation error
- Service unavailable or payment not processed — returns 402 or 503

## How this service works

EU Taxonomy alignment check for sustainable-finance and compliance agents. Returns whether an activity qualifies as sustainable: DNSH criteria, technical screening, green asset ratio, and Article 8/9 fund implications.

## Output

Returns a structured response indicating whether the queried activity is EU Taxonomy-aligned, including a pass/fail on Do No Significant Harm (DNSH) criteria, technical screening criteria results, the applicable green asset ratio, and implications for Article 8 and Article 9 SFDR fund classification.
