## 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-coffee-ethical-sourcing-check-8634392c
```

Example prompt: Is Stumptown Coffee ethically sourced? I want to know their Fairtrade and Rainforest Alliance certification status, whether they publish farm-gate prices, any red flags, and if there are better-sourced roasters I should consider instead.

## When to prefer this

Choose this endpoint when you specifically need ethical sourcing intelligence for a coffee brand, including certification cross-referencing across Fairtrade, Rainforest Alliance, and direct trade sources, plus farm-gate price transparency signals. Prefer this over generic ESG endpoints when the query is specifically about coffee roasters or coffee brands rather than broader commodity sustainability or general brand ethics.

## Known failure modes

- Brand or roaster not found in sourcing databases — returns empty or null certification fields
- Brand name is ambiguous or misspelled — may return results for a different brand or no match
- Data may be stale if certification status recently changed — certifications can lapse
- Small or ultra-local roasters may have no indexed data in Transparent Trade Coffee, Cup of Excellence, Fairtrade, or Rainforest Alliance datasets
- Payment failure (x402 protocol) if USDC balance is insufficient — returns 402 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 a JSON object with the queried roaster or brand name, a list of certification statuses (Fairtrade, Rainforest Alliance, etc.), a price transparency signal indicating whether farm-gate prices are published, evidence of direct trade transparency, any sourcing red flags, and a list of better-sourced roaster alternatives with explanations of why they rank higher.
