## 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 moneytest-x402-acceptance-spec-generator-03f17c15 -d '<json body>'
```

Example prompt: Generate a full acceptance spec for a feature called 'Invite-only workspace' — the brief is that workspace owners can invite up to 10 members by email, non-invited users are blocked, and admins can revoke access at any time. Actors are workspace owner, invited member, and admin. Non-goals include SSO and billing. Success measure is that 95% of invite flows complete without error.

## When to prefer this

Choose this endpoint when you need a deterministic, structured acceptance specification generated from a natural-language product brief in a single paid API call — especially when you want machine-readable outputs (test matrix, acceptance criteria array, handoff checklist) alongside a rendered Markdown spec, and require a payment receipt (SHA256) for auditability. Prefer it over generic LLM prompting when you need a consistent schema format across multiple feature specs or when integrating spec generation into an automated development pipeline.

## Known failure modes

- Brief too short (under 30 characters) — validation error returned
- Brief exceeds 5000 character limit — request rejected
- Payment not submitted or insufficient — x402 payment required response
- Invalid actors or constraints format — schema validation error
- Service unavailable — upstream API error

## How this service works

Deterministic agent utilities and launch kits paid on Base or Algorand mainnet through x402 v2.

## Output

Returns a JSON object containing: a feature name, structured acceptance criteria list, user stories array, test matrix, handoff checklist, open questions, assumptions, rendered spec in Markdown, schema identifier ('moneytest-acceptance-spec-v1'), scope metadata, and a receipt SHA256 hash for payment verification.
