## 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 dealpulse-subscription-cancellation-letter-generator-c2b2d031
```

Example prompt: Can you draft a formal subscription cancellation demand letter for me? I'm in California, the seller is Acme Streaming Co., they charged me $89.97 total without my consent, and they've been blocking my attempts to cancel.

## When to prefer this

Use this endpoint when a consumer needs a formal, legally-inflected written demand to send to a subscription company — particularly when cancellation has been obstructed or charges were made without affirmative consent. Prefer this over generic letter generators because it is state-aware, referencing jurisdiction-specific consumer protection law. Best for US-based subscription disputes in the supported states.

## Known failure modes

- Missing required 'state' parameter returns an error
- State code not in the supported list (CA, NY, DC, VA, IL, VT, OR, HI, DE, FL) may produce a generic or empty letter
- Empty response schema means output structure may vary unexpectedly
- Payment failure via x402 micropayment returns 402 status before letter is generated
- Invalid or missing total_charged may produce a placeholder amount in the letter
