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.

Example use cases

Spec from product brief for new onboarding flow

“Turn this brief into a full acceptance spec for 'Guided Onboarding': new users must complete a 3-step setup wizard before accessing the dashboard, skipping is not allowed, and success is measured by 80% wizard completion rate. Actors are new user and support agent; non-goals are in-app chat and video tutorials.”

Test matrix for payment feature

“Generate an acceptance spec for a feature called 'One-click checkout' — users can save a payment method and reuse it in one tap, actors are returning buyer and fraud system, constraints are PCI compliance and 3DS support, non-goals are crypto payments, and success is checkout time under 10 seconds for 90% of users.”

Handoff checklist for access control overhaul

“I need a structured acceptance spec for 'Role-based access control' — the brief is that admins can assign viewer, editor, or owner roles per project, actors are admin and team member, non-goals are LDAP and SSO, constraints are GDPR data minimization, and success is zero privilege escalation incidents in the first 30 days.”

When to prefer

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.

Side effects

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
