# ESGPulse Conflict Minerals & Responsible Sourcing Check

> ESGPulse Conflict Minerals & Responsible Sourcing Check is a paid API for AI agents from esgpulse.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Checks whether a smelter or company is RMI-conformant for conflict minerals (tin, tantalum, tungsten, gold, cobalt, lithium, mica) and returns Kimberley Process status for diamonds plus country-risk context.

## Facts

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 esgpulse-conflict-minerals-responsible-sourcing-check-2d4e5ab7
```

Example prompt: Can you check if Example Refining Co is RMI-conformant for cobalt and whether they have any country risk flags, particularly around DRC?

## When to prefer this

Use this endpoint when an agent needs to verify whether a specific smelter or company meets RMI conflict mineral standards for 3TG metals, cobalt, lithium, or mica, or needs Kimberley Process status for diamond suppliers. Ideal for supply chain due diligence, ESG reporting workflows, procurement compliance checks, and sourcing audits where regulatory conformance evidence is required.

## Known failure modes

- Unknown smelter or company name returns no match or empty result
- Metal type not supported returns an error or null verdict
- RMI database may lag behind real-world conformance updates, causing stale results
- DRC and other high-risk countries may return multiple overlapping risk categories requiring interpretation
- Ambiguous company names may return results for a different entity

## 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 a JSON object with the metal queried, a verdict rating (e.g. conformant or non-conformant), the smelter or company name, RMI conformance status, and an array of country risk context entries listing countries and their risk categories (e.g. conflict-affected). For diamonds, also includes Kimberley Process participant status.
