## 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-checker-2c6ba351
```

Example prompt: Can you check if Blue Bottle Coffee is ethically sourced — I want to know their Fair Trade, direct trade, and Rainforest Alliance certification status, whether they're transparent about farm-gate prices, any red flags, and if there are better-sourced roaster alternatives?

## When to prefer this

Use this endpoint when you need to specifically verify the ethical sourcing credentials of a coffee brand, including certification status and price transparency signals. Prefer this over generic ESG endpoints when the query is narrowly about coffee supply chain ethics rather than broad corporate ESG scores.

## Known failure modes

- Unknown or very small coffee brand with no data in reference databases — returns null or low-confidence result
- Brand name ambiguity causes misidentification (e.g. generic name matching multiple roasters)
- Stale certification data if a brand's status changed recently
- HTTP 402 if payment not attached
- HTTP 400 if brand name parameter is missing or malformed

## How this service works

Ethical sourcing check — is this coffee brand ethically sourced? Fair trade, direct trade, and Rainforest Alliance certification status, farm-gate price-transparency signal, red flags, and better-sourced roaster alternatives, grounded in Transparent Trade Coffee, Cup of Excellence, Fairtrade, and Rainforest Alliance data.

## Output

Returns the coffee brand's Fair Trade, direct trade, and Rainforest Alliance certification status, a farm-gate price transparency signal, any ethical sourcing red flags, and a list of better-sourced roaster alternatives, grounded in Transparent Trade Coffee, Cup of Excellence, Fairtrade, and Rainforest Alliance data.
