## 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 penny402-oblique-strategy-card-generator-5b4a3c87 -d '<json body>'
```

Example prompt: I'm totally stuck on my product naming process — can you generate an original oblique strategy card about branding to shake things up?

## When to prefer this

Choose this endpoint when you need a single, fresh, never-repeated oblique strategy card generated on demand — especially when you want topic-steering without cache pollution. Prefer it over static card decks or pooled systems when novelty and originality on every call matter, or when you want to integrate a pay-per-use creative constraint into an agentic workflow without storing or reusing previous cards.

## Known failure modes

- Topic exceeds 140 characters — card may not be generated or topic may be truncated
- Body payload exceeds 4 KB limit — request rejected
- Payment not settled (unpaid 402) — card not produced, 402 response with pricing terms returned
- Model fails to produce a card — no result returned and nothing is settled
- Malformed JSON body — request rejected

## How this service works

One original constraint card in the tradition of lateral-thinking decks: a short instruction, reversal or question you can apply to whatever is stuck, written fresh by a model at high temperature on every call. The cards are ours, never a card from any published deck. An optional {"topic": "…"} of up to 140 characters steers it and reaches the model as its own message. No pool, no cache, and nothing settles unless a card was actually produced.

## Output

A single original lateral-thinking constraint card returned as JSON — a short instruction, reversal, or question generated fresh at high temperature by a model, never cached, never sourced from any published deck. If a topic was provided it will be reflected in the card's angle.
